Hi everyone,
I’m trying to set up a Waveshare 1.44” LCD HAT (128x128, ST7735S) on my Raspberry Pi, but I’ve been stuck for days. Here’s what I’ve tried so far:
1.Installed and tested fbcp-ili9341 with the ST7735R configuration—no luck.
2.Attempted to load fbtft_device drivers, but the module isn’t available in my kernel (6.6.74+rpt-rpi-v7).
3.Used Waveshare’s LCD-show repository, but it doesn’t seem to support the ST7735S model.
4.Tried sending SPI data directly using spidev in Python—only getting [0] responses.
5.Ran framebuffer tests on /dev/fb0 (e.g., cat /dev/urandom > /dev/fb0), but nothing appears on the screen.
The display only shows a white screen, no matter what I do. SPI is enabled in /boot/config.txt, and GPIO pins seem correctly configured (checked with raspi-gpio).
If anyone has successfully set up this specific display or has any advice on what else to try, I’d really appreciate it. I’m reaching out to Waveshare as well but wanted to check here for any tips or solutions.
Thanks in advance!
