V-TFT - Touch screen calibration, ability to save
Posted: 28 May 2014 11:53
I'm a newcomer to V-TFT, and although I'm still finding my way around, I have found it a fantastically productive tool with which to make rapid prototypes. Congratulations on making TFT display simple.
However, after completing my project using V-TFT on a Mikromedia for ARM Stellaris M3 board, I wanted to remove the touch panel calibration set-up screen at each start-up. It should be possible to run this routine once only and then save the calibration constants for that board in non-volatile memory. But this is not simple because any attempts to modify the calibration code are overwritten each time V-TFT is run.
I see that this feature to save touch panel calibration is requested by other users and I am presently trying to follow their suggestions. (without success at the moment, but that could be my fault
A simple function call to save TP calibration constants would be very much appreciated.
