Hi Ame!Is BL a feed for the backlight? Or a control signal for a transistor driver for the backlight?
Also, you should probably be powering the display from 3.3V, not 5V, in case you damage your GPIOs.
Ok. How little I know Image may be NSFW.
Clik here to view.
As per diagram and this what I can see on the back of the board it is backlight.
When I unplug it screen goes black. If I connect it to 3v it lights up. If I connect it to some random pins lights up also.
I have tried to connect VCC to 3.3v and screen goes much dimmer.
But ha. Regardless what I do, Raspberry Pi OS 32bit is my enemy now. I followed https://github.com/juj/fbcp-ili9341 as this apparently should work with ili9342. I tried https://github.com/32teeth/Generic-ILI9342 no luck im getting other errors.
Honestly, I have not even yet started to suffer from coding what and how this wee TV would play in loops, because of stoopid screen, which is just perfect ratio and size, but does not get connected and coded.
Should I try installing different os? I have spent a whole day to find hdmi normal people plug and play screens, but these are or too big, or out of proportions.
