This topic about Enabling Human Interface Device compliant multi-touch panels for VIM3 board under Linux ubuntu 18 with kernel 4.9.
This functionality is a very big deal when a multi-touch panel is required. It is enabled in the kernel mainline by default. I don’t know why this functionality is not enabled in fenix project by default.
modify kernel config file kvims_defconfig located at:
or (newer fenix):
Add the following lines:
recompile the project and flash to the board.
I have tested it with the following 7-inch multi-touch panel: HX0701601 from https://www.grahowlet.com/
and it worked perfectly
