Ksenia Kondrashova / Mbed 2 deprecated Temp_&_RH_at_TFT_with_touchscreen-RUS

Русифицированная версия программы для измерения температуры и отн. влажности и вывода информации на сенсорный TFT

Dependencies:   FT800_2 HYT mbed

Компоненты

Подключение

Отладочная плата к TFT-модулю

Отладочная плата подключается к модулю через переходник Break Out Board 20. На плате-переходнике используется 6 сигналов: SCK, MOSI, MISO, SS (интерфейс SPI), PD (powerdown) и INT (interrupt).

Питание должно быть подано не только на VDD, но и на BLVDD - подсветку экрана. Соответствующие выводы можно просто соединить между собой:

Отладочная плата к датчику серии HYT

К датчику отладочная плата подключается по I2C. Не забываем про подтяжку к питанию:
