Hi,
I am testing a simple ESP32 CAM connect to a TFT lcd by the:

https://www.survivingwithandroid.com/esp32-cam-tft-display-picture-st7735/

It is just not shown any thing on the lcd.
I have tested the ESP32 CAM works well itself, I mean it works as web server by the examples build in Arduino IDE, and the TFT works fine with Arduino UNO separately at least for the example code 'graphicstest'.
What can be?
Thanks
Adam

 

Maybe you used VDD pin to power your ESP-CAM
You should not use VDD pin to power the ESP32-CAM, power the ESP32-CAM through the 5V pin and GND.

Here is my code and my TFT_7735(5v power) pin out.
