- /* ------------- TOUCH SCREEN CALIBRATION (how to) -----------
- Touch Screen are not all the same and needs a calibration, you will see
- yourself by load touchPaint.ino example, try to paint all over the screen!
- If you have space on one or more side you prolly need to calibrate values
- ---- perform calibration ----
- To perform the touch screen calibration, load libTouchSCalibration.ino and open serial terminal:
- (you have to put data inside RA8875/_utility/RA8875Calibration.h)
- 1) the lowest value of x by touch the top/left angle of your tft, put value in TOUCSRCAL_XLOW
- 2) you can get the lowest value of y in the same time, put value in TOUCSRCAL_YLOW
- 3) the highest value of x by touching the lower/bottom corner of your tft, put the value in TOUCSRCAL_XHIGH
- 4) in the same manner you get the max value of y, put that value in TOUCSRCAL_XHIGH
