MOD-LCD2.8RTP
TFT COLOR LCD module with UEXT connector for ESP32-EVB and ESP32-POE
Using MOD-LCD2.8RTP requires non-standard SPI for the display and I2C for the touch screen
The non-standard part of the SPI is the lack of MISO which is Data/Command selection pin (refer to controller's datasheet) which has to be set as output.
UEXT pinout:
| UEXT column 1 | UEXT column 2 | Function |
|---|---|---|
| 1 - 3.3V | 2 - GND | Power pins |
| 3 - NOT USED | 4 - NOT USED | UART pins not used |
| 5 - SCL | 6 - SDA | I2C pins used for touch component |
| 7 - D/C | 8 - MOSI | SPI pins sans MISO used for display |
| 9 - CLK | 10 - CS | SPI CLK/CS for display |
