Action
Execute the touch screen calibration routine.
This is all in one routine with displaying prompts on the screen and updating of the REG_TOUCH_TRANSFORM_A-F registers.
Syntax
CmdCalibratex
Remarks
The calibration procedure collects three touches from the touch screen, then computes and loads an appropriate matrix into REG_TOUCH_TRANSFORM_A-F. To use it, create a display list and then use CmdCalibrate. The co-processor engine overlays the touch
targets on the current Display List, gathers the calibration input and updates REG_TOUCH_TRANSFORM_A-F.
Note: You can Automatically let Bascom do the Screen calibration for you.
Or if you want to force an Screen calibration at anytime:
| 1. | Press on the LCD panel |
| 2. | Reset your project |
| 3. | When you release from the LCD the Screen calibration message will appear. |
To enable this mode, set LcdCal = 1 from the FT800.inc file.
Const LcdCal = 1 ' Prompts for LCD Calibration (if not previously done)
