Здравствуйте. Может кто подсказать как управлять STA309A, или TAS5508 с arduino? Управление идет по i2C, а вот какие данные отправлять не совсем понятно. Например, для STA309A нужно отправить массив значений только на эквалайзер

};
А там параметров намного больше.
А Вы дэйташит на него внимательно изучали?
Даташиты не очень умею читать в части управления, многого не понимаю. Просто есть программа для конфигурирования этих чипов, это из нее.
Так что Вы хотите, чтобы кто-то внимательно изучил дэйташит и пересказал Вам?
Но если Вы не понимаете сам дэйташит, то почему думаете, что сможете понять пересказ?
Не так. Просто я не понимаю, мне все эти массивы слать туда, или как-то проще можно сделать.
Это из даташита громкость, с программной конфигурацией совсем не похожи. Как это понять?
kimmel.dima , как разберетесь, черкните сюда. У меня вопрос какая минимильная инициализация является необходимой для запуска.
У самого мастер кит BA2070 валяется на TAS5504A (+ PL1705 + 2 PCM1808 ) и усилители BA2071 http://lib.chipdip.ru/269/DOC000269591.pdf . Кончилась atmega8 (греется, кз на пине было) , она с кнопок громкости управляла ей. TAS5504A была куплена новая и заменена. Техподдержки на мастер кит нет, прошивки сказали нет (секрет), покупайте новую линейку усилителей. // А зачем , раз такая низкая надёжность и не ремонтопригодность при потраченных 8т.р. ?
Так что единственный вариант починить через arduino .
Схема BA2070 ( BM2070) на TAS5504 к BM2071 http://masterkit.ru/zip/bm2070.pdf
Ок. Примерно представляю, что надо слать, а что конкретно - не знаю.
Подскажите пожалуйста, по таблице из даташита:
Правильная посылка получается?

Начните с букваря.
ну сами подумайте, кто будет ковыряться в чужом код на 1400 строк...
Это не мне. Человек попросил какую-нибудь информацию по управлению tas, я скинул (мне не жалко).

В каком месте написал, что не умею???
По делу есть что сказать?
Нашел код для sta308. Сама микросхема пока едет, проверить в железе не могу. Посмотрите знающие люди, ошибок много?

kimmel.dima , как разберетесь, черкните сюда. У меня вопрос какая минимильная инициализация является необходимой для запуска.
У самого мастер кит BA2070 валяется на TAS5504A (+ PL1705 + 2 PCM1808 ) и усилители BA2071 http://lib.chipdip.ru/269/DOC000269591.pdf . Кончилась atmega8 (греется, кз на пине было) , она с кнопок громкости управляла ей. TAS5504A была куплена новая и заменена. Техподдержки на мастер кит нет, прошивки сказали нет (секрет), покупайте новую линейку усилителей. // А зачем , раз такая низкая надёжность и не ремонтопригодность при потраченных 8т.р. ?
Так что единственный вариант починить через arduino .
Схема BA2070 ( BM2070) на TAS5504 к BM2071 http://masterkit.ru/zip/bm2070.pdf
Также хочу разобраться как управлять этим набором.
Пишите в личку , может совместно осилим

А код посмотреть можно? У меня полнотью управляется 08-ая, но с дисплеем пока заморочки.
Код написагн для PIC18
Вам врядли подойдет
Допилил код для tas5508. В протеусе все работает.
