DSI display
March 26, 2024, 10:58
Hi everyone! I am using a CM4 module. I wanted to use a 7 inch DSI display which uses the ILI9881 IC. I got the inspiration to use this from the cutiepi tablet project. I designed a PCB and added dtoverlay = cutiepi-panel to my config.txt. I get output to my display but it blurry and the entire row lights up. Any help would be appreciated! Thanks a lot!
Quick
Link?
https://github.com/cutiepi-io/cutiepi-board to keep neat
Sorry thanks!
Datasheet of the screen I am using
You flashed the micro SD card on the cutiepi?
Apparently it runs on its own os too
Actually that might be a different one
Yeah I think they developed their own OS. But I was just looking to implement a way to use the display
I referenced their Schematics and used the drivers mentioned in the link above
I think the os is necessary
Try it anyway
I did try it, but the hardware I am using is quite different from their project so it wouldn’t work on my PCB. It doesn’t boot. But I referenced their Display circuit to implement it within my project
They're docs don't consist of much else which is annoying
Yup the documentation is a little inadequate
They suggest to use the CM4 board didn't they?
I am somewhat happy that I can get some sort of output on my display but not sure how to proceed
I am using a CM4 module
Yes and that's what they suggest
I can share the schematics of my PCB with you
Sure
We don't need any PCB right now right? What does the PCB do?
Its got multiple aspects
HDMI, an M.2 port for network cards, an Audio card for audio and Mic
I think it might be a driver issue
For now tho can we remove that from the equation to simplify things?
I think if we build up slowly and find the problem deep down first it'd be better. Your project tho
Its an IOT pill dispenser
Using a pi
Fun, have you tried without the PCB tho? You can work it in later
Are you talking about the DSI screen?
Would need a PCB to try it
You only need the CM4 board don't you??
Would have to use it with a carrier board
