@felmue, thanks very much, This worked perfectly.

M5

Thank you.

Can any one get this simple GC9A01 test to run on the M5Dial

• https://github.com/carlfriess/GC9A01_demo

My goal is to have LVGL running on the M5Dial so I am working my way through the display issues at this time.

GC9A01 driver

Hmm, no I did not. Let me do some research and try to find the driver

Does anyone know the correct pin assignment for the M5Dial SPI bus? I am trying to run LVGL with TFT_eSPI. I have tried the pin assignments I obtained from the M5Dial specifications page but I am having no luck. Here is what I have so far

// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins

#define TFT_MOSI 5 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 6
#define TFT_CS 7 // Chip select control pin
#define TFT_DC 4 // Data Command control pin
#define TFT_RST 8 // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL 9 // LED back-light

I am trying to run LVGL on the M5Dial using Arduino and LovyanGFX. Does anyone have any examples?
