Currently the config option: CONFIG_INPUT_GT911_MAX_TOUCH_POINTS is not defined for the Giga display shield and defaults to 1. The valid range is 1-5, I have done most of my own testing using 3 with the ArduinoGiga-zephyr I have a PR against the ArduinoCore-zephyr project which allows me to define a callback in the Arduino system: arduino/ArduinoCore-zephyr#134 And a version of the Arduino touch library with some support, the fork/branch https://github.com/KurtE/Arduino_GigaDisplayTouch/tree/zephyr And an example sketch that does touch paint. arduino/ArduinoCore-zephyr#92 (comment) Note: my version of the Arduino touch library has no support for gestures Signed-off-by: Kurt Eckhardt <kurte@rockisland.com>
