Linux Framebuffer drivers for small TFT LCD display modules. Development has moved to https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/tree/drivers/staging/fbtft?h=staging-testing
I connected a ILI9481 based TFT (reg(0x00BF) 00 02 04 94 81 FF to my raspberry pi zero using 8bit parallel wiring. Backlight is on, besides that, nothing happens.
lcd_ic doesn;t give me the same output as Arduino wich is kinda strange
I double checked the wiring, seems ok. So I checked (just to make sure) with probe.py but that gives me -1 on all the pins. I did not connect the 3.3V but only used the 5V.
I tried modprobe and took the init from the SPi part but still nothing.
I assume the GPIO pins have to be in BCM format.
I have the datasheet and I think I have to write my own overlay for it since the only reference to ILI9481 is SPI based.
