Hi, I am trying to compile the sketch TouchWakeUp in your book Learn ESP32 with Arduino IDE V3.2 but I got Compilation error. It is with function: void print_wakeup_touchpad();. I get this error in both Linux and Windows 11. When I try to search: cannot convert ‘int (*)()’ to ‘touch_pad_t’ in initialization I can’t fin any answers. Please help.
