Has the TpCal example been deprecated? I’ve seen it mentioned in some earlier posts.
I noticed the function
static void xpt2046_corr(int16_t * x, int16_t * y) in the XPT2046.c file. From my understanding, it auto-calibrates the touch coordinates as you use it? Is this correct?
Is there any way to manually calibrate the touch controller? I used a screen before and it had a function to touch all 4 corners to calibrate it.
