    NHD-2.4-240320CF-CSXN#-F backlight driver

    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 ...

    Thank you for the reply! Initialization sequence: I was fiddling with the functions to get them to work and this is how I left the code. I can indeed un-comment the extra initializations. I apologi...

    My test code is here: https://drive.google.com/file/d/12DP3WwnvoRKivdJ4pV5Kp8ve7FpO3dgs/view?usp=sharingAt WRITE_CYCLE_BUSY_WAIT_COUNT=250, I get 8.5 fps, and the display is stable: https://photos....

    Greetings folks! I am using a Raspberry Pi and the 16-bit interface mode. For now, I am using plain GPIO operations to toggle the pinouts. My observation is: I cannot paint a frame faster than what...

  • Ihab Awad commented,

    Thank you very much for the support so far. I can report success! First, this is the display driven by an ESP32 development board. The Newhaven demo code is working well: https://photos.app.goo.gl/...

  • Ihab Awad commented,

    Thank you very much! This is not a direct Newhaven question -- I was just unable to find information from the ARM system integrators, and I wondered if you happened to have encountered this. What I...

    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

    Greetings folks. I am using your example code:https://github.com/NewhavenDisplay/NHD-2.4-240320CF-Cxxx_Example I have wired up my NHD-2.4-240320CF-CSXN#-F display as per the following:https://docs....

    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...
