Ksenia Kondrashova / Mbed 2 deprecated Temp_&_RH_at_TFT-demo

Very simple SW polling HYT humidity & temp sensor and show received data at TFT [NO TOUCHSCREEN USED]

Dependencies:   FT800_2 HYT mbed

There is only one screen with relative humidity and temperature data received from HYT sensor, no touchscreen functionality.

Hardware

For documentation on the HYT and FT800 libraries, please refer to the respective library pages.

Connection

MCU-board to TFT-module

MCU-board is connected to TFT-module via Break Out Board. You need 6 signals to connect: SCK, MOSI and MISO are connected to a SPI channel, SS is the chip select signal, PD work as powerdown and INT for interrupts from TFT to MCU.

You have to connect VDD to BLVDD at Break Out Board if you use the board:

MCU-board to HYT sensor

MCU-board is connected to sensor via I2C. Remember to use pull-up resisrors there:
