Ksenia Kondrashova / Mbed 2 deprecated FT800_demo_for_habr

Very simple SW using FT800 graphic lib [NO TOUCHSCREEN USED]

Dependencies:   FT800_2 mbed

Demo for FT800 graphic lib. There is only one screen with seconds counter and Clock widget, no touchscreen functionality.

Hardware

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:
