9 years ago If you change the chip select, you need to make your own overlay.
Copy this: https://github.com/notro/fbtft/blob/master/dts/overlays/rpi/pitft-overlay.dts
Then change to reg =<1>; and remove the touch node.
See here for how to build the overlay: https://github.com/notro/fbtft/wiki/FBTFT-RPI-overlays
Hello.
I wish to use PiTFT Mini Kit on Rpi 2.
I followed the instructions and did that: sudo REPO_URI=https://github.com/notro/rpi-firmware rpi-update reboot
This is my config.txt: dtparam=i2c_arm=on dtparam=spi=on dtoverlay=pitft
I try to use this way: sudo modprobe spi-bcm2708 sudo modprobe stmpe_ts sudo modprobe fbtft_device name=pitft cs=1 rotate=90
I wire the LCD to CS1 on Rpi and i don't use the touchscreen.
I've got only white screen.
Maybe i have to modify the dtoverlay somehow instead of use the following? sudo modprobe fbtft_device name=pitft cs=1 rotate=90
If yes, please, how can i do that?
This is my dmesg:
