Re: Unable to use SPI display. Help please.

One of my screens has a green protection film. The other one doesn't have any protective film - not sure if it came with one and I removed it!

Thanks a lot for all your willingness everyone. Even if this does not work, it is heart warming to see lengths people go to, to help others. :-)

Re: Unable to use SPI display. Help please.

Re: Unable to use SPI display. Help please.

Here is some more trial on this display. [in fact two of the displays both claim st7735]. Sadly, no outcome, other than glowing white screen. When I try to loop and write pixels, I get a delay depending on how much data it seems to write. Still nothing shows up on screen when I do display.pixel > x,...

Re: Unable to use SPI display. Help please.

Re: Unable to use SPI display. Help please.

Hi Marfis You are correct. I deleted the mpy and now the st7735 subclassing works. However up on deleting all the compiled versions and retrying the code, still nothing is visible on the screen.

I used the st7735.py from your post. - Clean reflash - connected to it from screen as ttyUSB0 - connect to wifi -> open webrepl and loaded the following files >>> os.listdir('.') ['boot.py', 'webrepl_cfg.py', 'st7735.py', 'rgb.p...
