I need help wiring ESP32 and TFT ... Gpio25 ---> CD doubt ...

[rselow]

What is the function of the CD pin (Wiring ESP32 and TFT) ? I haven't found this pin on the TFTs I know. Should I buy a TFT with this pin? What's the code?

I have the same problem ... It seems the we we should connect it to the LED pin;

grbl_controller_esp32/grbl_controller_esp32/config.h

Line 170 in aa92068

#define TFT_LED_PIN 25 // pin connected to led of lcd; pin has to be high to set led ON

Indeed : based on the #define line inthe code, it should be the LED pin of the LCD

I tested it and that's right! Thanks
