Very simple SW using FT800 graphic lib [NO TOUCHSCREEN USED]
Demo for FT800 graphic lib. There is only one screen with seconds counter and Clock widget, no touchscreen functionality.
Hardware
- TFT module uxTouch by Riverdi
- Break Out Board 20 by Riverdi
- Any mbed platform with SPI interface and 2 free GPIO for PD and INT signals
Connection
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:
