Greetings Newhaven, I am using an NHD-2.4-240320CF-CSXN#-F in my circuit. The backlight voltage, 3.1V, is much lower than the "typical" (about 20V) voltage of most TFTs I have used. Does Newhaven h...

Hi folks. I finally figured out the problem. I hope this is of use to others on this forum! Writes to the GPIOs of the Raspberry Pi do not necessarily complete "immediately" -- they are subject to ...

Oh you're kidding. :( I'm so sorry for making such a fundamental mistake! I have been using an ESP32 for years, with 3.3V logic levels. Thank you so much for the tip!!!! Ihab

NHD-2.4-240320CF-CSXN#-F support from ARM processors
Hi folks, I am asking about the "8080" style parallel 8 and 16 bit interface displays such as: https://newhavendisplay.com/2-4-inch-sunlight-readable-tft-without-touchscreen/ Do you have examples...
