Debugging with Display ST7735

[Hans345]

Hi

I want to debug my Display ST7735 (128 x 128 px). For that i wrote a code which sets the screen line by line into green color. When i flash the code it works fine. When i try to debug nothing happens on the display. 

What can i do that the display changes the color during debugging?

Here you see the configuration of the debugger:

Here you see a screenshot of the code where each pixel (x,y) is set to GREEN color with SPI. w and h are the width and height of the display in pixel. 

This Code is from the adafruit library ST7735. 

Thanks for your answer,

Check signal timings with a scope or analyzer. 

Review data sheet check if you can read back registers or WHOAMI register.

Check back light enabled.  Fill frame buffer with different patterns.

Do you want to try testLines(uint16_t color)?
