I'm trying to activate the touchscreen of a generic display that uses I2C with a CM5 IO Board connected to an RGB parallel to MIPI DSI converter board (Waveshare 7-inch LCD with camera), modified to match my I2C touchscreen connections.
The specifications are:
Goodix GT9271 for 1024x600 (10.1 inches) connected through I2C0.
When using the Goodix overlay, or a custom one including similar configurations to Goodix, nothing links up and errors occur, as shown below.
However, when using touchscreens referenced from EDT FT5XX6, the touchscreen activates but is fixed at 800x480 resolution. What I would like is to change it to 1024x600 so I can have full display configuration.
There are 5 variants of the chip for various touch panel sizes:
FT5206GE1 → 2.8" .. 3.8"
FT5306DE4 → 4.3" .. 7"
FT5406EE8 → 7" .. 8.9"
FT5506EEG → 7" .. 8.9"
FT5726NEI → 5.7" .. 11.6"
I know this is not the ideal driver for my display, but it's the only way that makes everything work properly.
Please consider giving me some tips or advice. I'm open to receiving them![:D]( "Very Happy")
