Русифицированная версия программы для измерения температуры и отн. влажности и вывода информации на сенсорный TFT
Dependencies: FT800_2 HYT mbed
Компоненты
- Датчик температуры и относительной влажности HYT-271 / HYT-221 / HYT-939 от компании IST-AG
- TFT-модуль серии uxTouch от компании Riverdi
- Плата-переходник Break Out Board 20 от компании Riverdi
- Любая отладочная плата с поддержкой mbed, интерфейсами I2C и SPI interface двумя свободными линиями для сигналов PD и INT
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:
