Ksenia Kondrashova / Mbed 2 deprecated Temp_&_RH_at_TFT_with_touchscreen-ENG

HYT humidity & temp sensor polling / showing received data at TFT with capacitive touchscreen

Dependencies:   FT800_2 HYT mbed

HYT humidity & temperature sensor: polling and showing data at TFT via graphical controller FT800/FT801.

Hardware

For documentation on the FT800 library, please refer to the 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:
