This EVETFT Development Kit is a 3-inch, 240x400 Full-Color TFT with the EVE graphic accelerator and capacitive touchscreen. Simply plug in your controller of choice. the EVE engine uses 4-wire SPI for communication via a 30-pin FPC/ZIF connection.
This kit is based around an FTDI/BridgeTek FT811 Embedded Video Engine (EVE). All display, touch sensing, backlight control and audio features are controlled via the Embedded Video Engine which appears to the host MCU as a memory-mapped SPI device. The host MCU sends commands and data using SPI.
Some modifications are being made to the PCB design to improve reliability and manufacturability. The board cutout for the capacitive touch screen is being moved and the reset line to the EVE chip is being routed to the reset pin for the helper processor onboard.
The parts are being replaced as follows:
CFAF240400C0-030SC-A1-1 -> EOL and replace with CFA240400E0-030TC
CFAF240400C0-030SC-A1-2 -> EOL and replace with CFA240400E0-030TC-KIT
CFAF240400E0-030TN-A1-1 -> EOL and replace with CFA240400E0-030TN
CFAF240400E0-030TN-A1-2 -> EOL and replace with CFA240400E0-030TN-KIT
The current PCB design requires the capacitive touch screen FPC tail to be stretched and needs to be given more slack.
The reset line is not brought out to the helper processor on the current PCB revision so a reset toggle does not truly reset the whole system.
Current PCB revision: 10097 h0v3
