привет, поможете мне сделать код arduino из st7735 ds3231 и добавить ds18b20. Температура только от датчика ds18b20. Спасибо большое :)
/*
* some changes by Nicu FLORICA (niq_ro) from http://www.tehnic.go.ro
*
An example digital clock using a TFT LCD screen to show the time.
Demonstrates use of the font printing routines. (Time updates but date does not.)
Now it use RTClib library bu Nicu FLORICA
This examples uses the hardware SPI only. Non-hardware SPI
is just too slow (~8 times slower!)
Based on clock sketch by Gilchrist 6/2/2014 1.0
Updated by Bodmer, using library from https://github.com/Bodmer/TFT_ST7735
A few colour codes:
code color
0x0000 Black
0xFFFF White
0xBDF7 Light Gray
0x7BEF Dark Gray
0xF800 Red
0xFFE0 Yellow
0xFBE0 Orange
0x79E0 Brown
0x7E0 Green
0x7FF Cyan
0x1F Blue
0xF81F Pink
