Hello,
I have luckfox pico ultra w on which ubuntu is running. i have LF40-720720-ARK screen connected to it . i want to disable touch pins and set them as GPIO input. i have disable this by luckfox-config menu but i have not able to find out those pins on board. Can anyone share which pins are those so as to make it as gpio input pins .
Thank you!
Assistance required to disable only touch on pico ultra w
Hello, the RGB interface of Luckfox Pico Ultra includes the screen interface and the touch interface. The touch interface is not connected to the pin header. The position can be determined through the schematic diagram. https://files.luckfox.com/wiki/Luckfox- ... ra%20W.pdf
i want to configure 7 gpio pin as input excluding 32 ,33 ,40 ,41 as i have used them as I2C and UART purpose. can you share them ?Crocodile wrote: ↑2025-08-26 2:32 Hello, the RGB interface of Luckfox Pico Ultra includes the screen interface and the touch interface.

Apart from 32, 33, 40, and 41, the other pins are mostly used for RGB. If you don't use WIFI, there are 14 pins that can be connected from the WIFI pads, or it is more recommended to use the GPIO expansion chip (I2C driver, capable of mounting multiple ones)
can you suggest which is supported by luckfox pico ultra w?
If you are using the Luckfox Pico Ultra W, the option with higher feasibility is to use the IO expansion chip (the pins occupied by the WIFI module cannot be used, and separating the touch pins for use is less feasible).
