если ты имеешь в виду птичку с лева в верху то делал... сторочка myGLCD.setBackColor(BLACK); делает затирание с другими цветами, но по чему не работает с черным.... вот это странно. ставлю RED и фон у цифр красный, цифры в png, но не моргает и затирается, а если BLACK то фон у цифр ясно что черный, но цифры не в png а белые и продолжают налипать, ПОЧЕМУ...... только с черным такое? вот в чем вопрос, по идеи черный должен работать как и другие цвета.....
Черный - это гашение всех rgb - может оно как то криво на аппаратном уровне работает. Сделай фон НЕ ЧЕРНЫМ для всех экранов проекта. Тогда правки во фруктовой библиотеке отменить надо скорее всего.
myGLCD.setTextColor(WHITE, BLACK);...... не моргает, не затирает
так .....myGLCD.setBackColor(BLACK);
myGLCD.setTextColor(WHITE, BLACK);......... не моргает, не затирает
наоборот ......... myGLCD.setTextColor(WHITE, BLACK);
myGLCD.setBackColor(BLACK);.........заголовки белые , данных нет
меняем цвет
myGLCD.setTextColor(WHITE, RED);....... не мигает, не затирает, фон черный
так ставим ....myGLCD.setBackColor(RED);
myGLCD.setTextColor(WHITE, BLACK);.......моргает, затирает, фон красный, цифры белые
так ставим......myGLCD.setTextColor(WHITE, BLACK);
myGLCD.setBackColor(RED);........ моргает, затирает, фон красный, цифры png
так и еще встертил на просторах инета что во фрукте
Функция фонового цвета обычно использовалась с «классическим» шрифтом для перезаписи старого содержимого экрана новыми данными.Это работает только потому, что эти символы имеют одинаковый размер;это неразумно делать с пропорционально разнесенными шрифтами с символами разных размеров (которые могут перекрываться).
стандартный шрифт который вообще не указывает только размер
myGLCD.setTextSize(3);
myGLCD.setTextColor(WHITE, BLACK);
и даже с myGLCD.setColor(WHITE);
работает отлично не моргает и затирает.
как я понял с описания выше, затирание со стандартным шрифтом происходит потому что он квадратные семитричные символы имеет, а мне они не подходят, мне нужны выше и ужи, да и он как из майн крафта , уродлив. вот и вся проблема. вообщем библа фрукта это та еще дрянь
Подозреваю что не ту либу тянет компилятор ! Просто удали файл либы с моими правками и проверь - ругнётся или нет ? В правках ЖЕСТКО указано 0xF800 (красный)
стапе. есть такая же библа Adafruit-GFX1. ща уберу. убрал теперь ругается. как ее переключить теперь на эту на Adafruit-GFX? ща гляну может версия старая. 1.5.6 последняя. ща перекачаю и заменю
короче оно использовало обе библы. но в одиночку 1.5.6 ругается. выкинул вернул старую она 1.5.3. теперь только одна , можно пробовать править вот(
ты правил 1.5.6 а она по ходу брала с 1.5.3. вот и не было результата)

// canvases, the address of which can be passed to drawBitmap() or
// pushColors() (the latter appears only in a couple of GFX-subclassed TFT
// libraries at this time). This is here mostly to help with the recently-
// added proportionally-spaced fonts; adds a way to refresh a section of the
// screen without a massive flickering clear-and-redraw...but maybe you'll
// find other uses too. VERY RAM-intensive, since the buffer is in MCU
// memory and not the display driver...GXFcanvas1 might be minimally useful
// on an Uno-class board, but this and the others are much more likely to
// require at least a Mega or various recent ARM-type boards (recommended,
// as the text+bitmap draw can be pokey). GFXcanvas1 requires 1 bit per
// pixel (rounded up to nearest byte per scanline), GFXcanvas8 is 1 byte
// per pixel (no scanline pad), and GFXcanvas16 uses 2 bytes per pixel (no
// scanline pad).
// NOT EXTENSIVELY TESTED YET. MAY CONTAIN WORST BUGS KNOWN TO HUMANKIND.

ругается на не совместимость с мега 2560 чет такое. так вот теперь реакция пошла:). это в сетупе myGLCD.setTextColor(WHITE, BLACK); . затирание идет но остается на фоне цифр мелкий не дотертый мусор. и цифра например обороты были 800 потом 1200 то 1 остается а за остальными мелкий не дотертый мусор. Подправил везде цвета, все ок. Не знаю че ты там на колдовал но затирание идет, но остается мелкий не дотерный мусор с зади цифр, и не вытерает первую цифру при увеличении цисла в 4ох на оборотах. я думаю со скоростью таже история будет, тока при увеличении до 3ех значного, 3ех значная улетает в право на надпись км/ч и там застывает.
в сетуп теперь нет нужды кидать цвет, кинул в пару мест где нужно и все что нужно стало красны и что нужно белым.
И не могу понять как прописать линимя цвет в Adafruit_GFX.cpp четко написано

// pushColors() (the latter appears only in a couple of GFX-subclassed TFT
// libraries at this time). This is here mostly to help with the recently-
// added proportionally-spaced fonts; adds a way to refresh a section of the
// screen without a massive flickering clear-and-redraw...but maybe you'll
// find other uses too. VERY RAM-intensive, since the buffer is in MCU
// memory and not the display driver...GXFcanvas1 might be minimally useful
// on an Uno-class board, but this and the others are much more likely to
// require at least a Mega or various recent ARM-type boards (recommended,
// as the text+bitmap draw can be pokey). GFXcanvas1 requires 1 bit per
// pixel (rounded up to nearest byte per scanline), GFXcanvas8 is 1 byte
// per pixel (no scanline pad), and GFXcanvas16 uses 2 bytes per pixel (no
// scanline pad).
// NOT EXTENSIVELY TESTED YET. MAY CONTAIN WORST BUGS KNOWN TO HUMANKIND.

This is the core graphics library for all our displays, providing a common
set of graphics primitives (points, lines, circles, etc.). It needs to be
paired with a hardware-specific library for each display device we carry
(to handle the lower-level functions).

// GFXcanvas1, GFXcanvas8 and GFXcanvas16 (currently a WIP, don't get too
// comfy with the implementation) provide 1-, 8- and 16-bit offscreen
// canvases, the address of which can be passed to drawBitmap() or
// pushColors() (the latter appears only in a couple of GFX-subclassed TFT
// libraries at this time). This is here mostly to help with the recently-
// added proportionally-spaced fonts; adds a way to refresh a section of the
// screen without a massive flickering clear-and-redraw...but maybe you'll
// find other uses too. VERY RAM-intensive, since the buffer is in MCU
// memory and not the display driver...GXFcanvas1 might be minimally useful
// on an Uno-class board, but this and the others are much more likely to
// require at least a Mega or various recent ARM-type boards (recommended,
// as the text+bitmap draw can be pokey). GFXcanvas1 requires 1 bit per
// pixel (rounded up to nearest byte per scanline), GFXcanvas8 is 1 byte
// per pixel (no scanline pad), and GFXcanvas16 uses 2 bytes per pixel (no
// scanline pad).
// NOT EXTENSIVELY TESTED YET. MAY CONTAIN WORST BUGS KNOWN TO HUMANKIND.

для оладки шрифта? наверное трудоемко, рисовать в ней весь шрифт. а почему именно для Gobold_Bold14pt7b, я вчера подобрал более подходящий шрифт, он и прорисовывается быстрее и цифры не вооружонным глазо раборчиво видно, а то гоболде 0869 не разборчивы, я вот этот подобрал Chosence_Bold16pt7b.
красавчик, все красиво затирает :). я и новый свой шрифт подложил, он чутка меньше, идеально работает. так а тепрь вот..... двоеточие почемуто мигает палочкой, при увеличении цифр до 4ех значно первая цифра не исчезает при падении до 3ох значной, ну и на последок данные обновляются каждые 2 секунды, в мониторе запросы так же затормозились до 1 запрос в 2 секунды (но это уже наврное по Макса чатси, тут уже нужно смотреть каким боком вывод данных и запросы связаны, почему вывод данных затормаживает запросы....) . Ты гений... за фишку с 1116 строкой спасибо, нужно запомнить..
Для ускорения надо сделать всем переменным копию с припиской last и обновлять только то что изменилось. С двоеточием - может оно так нарисовано в шрифте (потом посмотрю). С остающимся символом - надо использовать дополнительные возможности printNUM - с сделать что бы выводились нули, вместо первых цифр.
на страницах где меньше в половину инфы выводится достаточно быстро,первое, двоеточие вчера на этом шрифте были, второе, с ласт Маскс пробовал, говорит заметно мерцание, третье, printNUM уже испльзуется, чет перестала работать кнопка TouchCHECK, ну и не нашел пока что вариант дать линиям цвет и рамкам кнопок. вот сетч, пересмотри, может че увидешь

я не говорю что из за тебя, это гдето я уже накосячил, ща найду. с last.... правда, мне не хватит сала в голове, я даже не понимаю ни логику, ни как это правильно записать :(. уже испльзуется printNumI и printNumF
myGLCD.printNumF(FuelTrip, 1, 210, 145,'.',5);
myGLCD.printNumI(PumpRPM, 210, 180,5); забыл что делает 5 в конце.... отступление чтоли?
5 позиций - вот так ещё можно(или как то так) - myGLCD.printNumI(PumpRPM, 210, 180,5,"0"); Это же надо использовать там где выводится дата вместо проверки на <10 просто в конце поставить 2, "0"); и ведущий ноль сам появится.
Извините ,что в вашей теме спрашиваю.Решил себе собрать БК на свою Джили мк кросс из проекта OBduino32.Я в песочнице тему создал бортовой компьютер на ардуино.Там и скетч и схема есть.Брал из форума Джили.Человек который собирал его,тестировал ,пропал с форума.В ощем собрать собрал я,но не могу наладить вывод температуры.Может посмотрите ,подскажите.
да я ставил на 4 позиции сьезжает с места цифры , конечно можно просто координаты вывода подправить чтобы обратно на метсо посадить, это то не столь важно и не играет роли. я так думаю, и с четерьмя позициями таже фигня
увы, как налипали на кучу так и налипают, через секунду уже каша из цифр можно сказать белое пятно...
Может она не скомпилировалась ? Запусти полную пересборку.
если ты имеешь в виду птичку с лева в верху то делал... сторочка myGLCD.setBackColor(BLACK); делает затирание с другими цветами, но по чему не работает с черным.... вот это странно. ставлю RED и фон у цифр красный, цифры в png, но не моргает и затирается, а если BLACK то фон у цифр ясно что черный, но цифры не в png а белые и продолжают налипать, ПОЧЕМУ...... только с черным такое? вот в чем вопрос, по идеи черный должен работать как и другие цвета.....
Что то напутано значит в основном скетче с setColor, setTextColor. Можно попробовать оставить один setBackColor(BLACK) в setup.
Все остальные места где есть setTextColor(...) изменить на setColor(...) с одной переменной цвета.
Черный - это гашение всех rgb - может оно как то криво на аппаратном уровне работает. Сделай фон НЕ ЧЕРНЫМ для всех экранов проекта. Тогда правки во фруктовой библиотеке отменить надо скорее всего.
ща сек.
в сетапе
myGLCD.setTextColor(WHITE, BLACK);...... не моргает, не затирает
так .....myGLCD.setBackColor(BLACK);
myGLCD.setTextColor(WHITE, BLACK);......... не моргает, не затирает
наоборот ......... myGLCD.setTextColor(WHITE, BLACK);
myGLCD.setBackColor(BLACK);......... черный экран
перед выводом данных
myGLCD.setTextColor(WHITE, BLACK);...... не моргает, не затирает
так .....myGLCD.setBackColor(BLACK);
myGLCD.setTextColor(WHITE, BLACK);......... не моргает, не затирает
наоборот ......... myGLCD.setTextColor(WHITE, BLACK);
myGLCD.setBackColor(BLACK);.........заголовки белые , данных нет
меняем цвет
myGLCD.setTextColor(WHITE, RED);....... не мигает, не затирает, фон черный
так ставим ....myGLCD.setBackColor(RED);
myGLCD.setTextColor(WHITE, BLACK);.......моргает, затирает, фон красный, цифры белые
так ставим......myGLCD.setTextColor(WHITE, BLACK);
myGLCD.setBackColor(RED);........ моргает, затирает, фон красный, цифры png
так и еще встертил на просторах инета что во фрукте
Функция фонового цвета обычно использовалась с «классическим» шрифтом для перезаписи старого содержимого экрана новыми данными. Это работает только потому, что эти символы имеют одинаковый размер; это неразумно делать с пропорционально разнесенными шрифтами с символами разных размеров (которые могут перекрываться).
стандартный шрифт который вообще не указывает только размер
myGLCD.setTextSize(3);
myGLCD.setTextColor(WHITE, BLACK);
и даже с myGLCD.setColor(WHITE);
работает отлично не моргает и затирает.
как я понял с описания выше, затирание со стандартным шрифтом происходит потому что он квадратные семитричные символы имеет, а мне они не подходят, мне нужны выше и ужи, да и он как из майн крафта , уродлив. вот и вся проблема. вообщем библа фрукта это та еще дрянь
Сначала сделай так
в сетапе
myGLCD.setTextColor(WHITE, BLACK);...... не моргает, не затирает
И проверь так ли это.
Потом замени фруктовую библиотеку на исправленную из 1779 (я там ещё немного подправил) и проверь что изменилось ?!
да в сетапе так же как и перед выводом данных myGLCD.setTextColor(WHITE, BLACK); не моргает и не затирает. заменил библу , тот же результат
И цвет не поменялся ? я там типа внутри белый на красный заменил
я вообще убрал какое либо опредиление цвета из скетча, только название шрифта. не мигает, не затирает, цвет цифр и заголовков белый

Просто удали файл либы с моими правками и проверь - ругнётся или нет ? В правках ЖЕСТКО указано 0xF800 (красный)
нет не ругается если даже изменю его имя, его нет, то компилится ,а вот если изменить имя MCUFRIEND_kbv.cpp то да ругается
Где то лежит такая же (похожая) библиотека и он тянет именно её !
стапе. есть такая же библа Adafruit-GFX1. ща уберу. убрал теперь ругается. как ее переключить теперь на эту на Adafruit-GFX? ща гляну может версия старая. 1.5.6 последняя. ща перекачаю и заменю
Через менеджер библиотек... А я какую версию правил интересно ...
короче оно использовало обе библы. но в одиночку 1.5.6 ругается. выкинул вернул старую она 1.5.3. теперь только одна , можно пробовать править вот(

ругается на не совместимость с мега 2560 чет такое. так вот теперь реакция пошла:). это в сетупе myGLCD.setTextColor(WHITE, BLACK); . затирание идет но остается на фоне цифр мелкий не дотертый мусор. и цифра например обороты были 800 потом 1200 то 1 остается а за остальными мелкий не дотертый мусор. Подправил везде цвета, все ок. Не знаю че ты там на колдовал но затирание идет, но остается мелкий не дотерный мусор с зади цифр, и не вытерает первую цифру при увеличении цисла в 4ох на оборотах. я думаю со скоростью таже история будет, тока при увеличении до 3ех значного, 3ех значная улетает в право на надпись км/ч и там застывает.
в сетуп теперь нет нужды кидать цвет, кинул в пару мест где нужно и все что нужно стало красны и что нужно белым.
И не могу понять как прописать линимя цвет в Adafruit_GFX.cpp четко написано
void Adafruit_GFX::drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1, uint16_t color)
как бы я не ставил всегда ошибка компиляции
myGLCD.drawLine(1,35,479,35, так RED, или 0xF800); всегда ошибка компиляции

Можно подкорректировать будет ... Пока проверь с прежним шрифтом.
Для "нового" шрифта в строке 1116 надо обе цифры 30 заменить на 27 - это максимальное по модулю число из последнего столбца таблицы GFXglyph шрифта.
Этот "новый" шрифт лучше выводить на один-два пикселя выше, что бы хостик буквы Q не попадал на линию разметки.
красавчик, все красиво затирает :). я и новый свой шрифт подложил, он чутка меньше, идеально работает. так а тепрь вот..... двоеточие почемуто мигает палочкой, при увеличении цифр до 4ех значно первая цифра не исчезает при падении до 3ох значной, ну и на последок данные обновляются каждые 2 секунды, в мониторе запросы так же затормозились до 1 запрос в 2 секунды (но это уже наврное по Макса чатси, тут уже нужно смотреть каким боком вывод данных и запросы связаны, почему вывод данных затормаживает запросы....) . Ты гений... за фишку с 1116 строкой спасибо, нужно запомнить..
Для ускорения надо сделать всем переменным копию с припиской last и обновлять только то что изменилось. С двоеточием - может оно так нарисовано в шрифте (потом посмотрю). С остающимся символом - надо использовать дополнительные возможности printNUM - с сделать что бы выводились нули, вместо первых цифр.
на страницах где меньше в половину инфы выводится достаточно быстро,первое, двоеточие вчера на этом шрифте были, второе, с ласт Маскс пробовал, говорит заметно мерцание, третье, printNUM уже испльзуется, чет перестала работать кнопка TouchCHECK, ну и не нашел пока что вариант дать линиям цвет и рамкам кнопок. вот сетч, пересмотри, может че увидешь

Теперь не будет мерцания !!! У printnum есть ещё возможности !!! TouchCHECK я никаким боком не касался.
У нас сегодня дует (тьфу тьфу тьфу) - я сваливаю до вечера виндсерфить.
я не говорю что из за тебя, это гдето я уже накосячил, ща найду. с last.... правда, мне не хватит сала в голове, я даже не понимаю ни логику, ни как это правильно записать :(. уже испльзуется printNumI и printNumF
myGLCD.printNumF(FuelTrip, 1, 210, 145,'.',5);
myGLCD.printNumI(PumpRPM, 210, 180,5); забыл что делает 5 в конце.... отступление чтоли?
ПРИКОЛЬНО, УДАЧНО ПРОВЕСТИ ДЕНЬ ;)
5 позиций - вот так ещё можно(или как то так) - myGLCD.printNumI(PumpRPM, 210, 180,5,"0"); Это же надо использовать там где выводится дата вместо проверки на <10 просто в конце поставить 2, "0"); и ведущий ноль сам появится.
ок, ща буду пробовать
Извините ,что в вашей теме спрашиваю.Решил себе собрать БК на свою Джили мк кросс из проекта OBduino32.Я в песочнице тему создал бортовой компьютер на ардуино.Там и скетч и схема есть.Брал из форума Джили.Человек который собирал его,тестировал ,пропал с форума.В ощем собрать собрал я,но не могу наладить вывод температуры.Может посмотрите ,подскажите.
Нужно у MaksaVV спрашивать. Он у нас спец по машинам.
не могу я побороть затирание первых цифр.
myGLCD.printNumI(RPM, 210, 215,5, "0"); не работает
myGLCD.printNumI(RPM, 210, 215,5, '0'); заламывает появляется много цифр штук 8
if (RPM>=10 && RPM<100) {myGLCD.print(" ", 210, 215); }; не работает
А почему 5 позиций ? Обороты могут быть выше 9999 ?
из описания:
printNumI(2000,50,50); // результат: "2000"
printNumI(2000,50,50,0); // результат: "2000"
printNumI(2000,50,50,5); // результат: " 2000"
printNumI(2000,50,50,6,'0'); // результат: "002000"
да я ставил на 4 позиции сьезжает с места цифры , конечно можно просто координаты вывода подправить чтобы обратно на метсо посадить, это то не столь важно и не играет роли. я так думаю, и с четерьмя позициями таже фигня
Вообщем надо увидеть ... фото хотя бы ... что именно не так с '0' в крайнем параметре ...
ок. ща сделаю
не стал делать фото, долго это. вообщем при такой строке
myGLCD.printNumI(RPM, 210, 215,5, '0');
показывает 00800 оборотов. да когда поднимаю до 1200 допустим то выглядит так 01200, при падении до 800 сново так 00800.
оно то затирает нулями, но во первых два нуля почемуто, во вторых не красиво выглядит с нулями
два нуля потому что ты задал 5 позиций, а 800 это три позиции - значит впереди два нуля.
можно перерисовать какой-нибудь символ в шрифте на пустоту и выводить его вместо '0'
пробел библиотека принципиально не выводит
подходяший символ для перерисовки # - он вроде нигде не используется
