In 2017 I made a digit clock using a Raspberry Pi 3 and a 480x320 GPIO display. The brand of the display was Kuman. Yesterday the display quit working and is no longeer available. I replaced it with a SunFounder brand display (SunFounder 3.5 Inch 480x320 Touch Screen IPS LCD SPI Display Monitor with Stylus for Raspberry Pi). It boots up and goes to the HTML site and displays the page that shows the time. The problem is the colors are incorrect. The background is white instead of black and the displayed time is the incorrect color. Nothing was changed on the micro SD card. The RPi OS is still the OS that was available in 2017. I assume the display driver needs to be replaced. How do I do that?
The colors are the inverse. My "work around " in html is to set the background to white. The original color of the characters was changed from darkorange to #0073FF. since this is the only thing I use it for, I can live with the workaround.
That sounds like a really cool project.Thanks for sharing your experience, and enjoy your clock!
