Open perdidor opened this issue 2 years ago • 1 comments

Hello. Thanks for your work. It compiles and runs successfully with esp-idf@esp32s3. But i need to support 8 same displays simultaneously. They are ordered and inder way to me from aliexpress . Is it possible? Any help appreciated. Thanks.

I haven't used more than one display in any of my projects. But you should have some options on implementation.

  • if the displays all need to be identical you could wire them all in parallel
  • if each display needs to be unique, you can parallel the SPI lines and provide dedicated DC/CS pins.

Very likely you will run into performance issues with more than a handful of displays due to SPI transfer speed.
