TFT LCD Panel

TFT LCD panels can be wired to the 2x4 expansion header of the PT1.

The following signals are necessary to drive the ST7735R:

PA1 (ESP_GPIO0)    ------> D/C
PA5 (ESP_CH_PD)    ------> SPI1_SCK
PA7 (ESP_RST)      ------> SPI1_MOSI

Additionally, the following connections should be made:

GND                ------> GND
                    \----> CS

VCC/3.3V           ------> VCC
                    \----> BACKLIGHT
                     \---> RES

In-development code can be found here. It could be expanded to support new displays: https://github.com/groupgets/purethermal1-firmware/tree/spi-display-st7735r
