V-TFT - Touch screen calibration, ability to save

#1 Post by AndyBentley » 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.

Hello AndyBentley and welcome to the MikroE forum,

You can write calibrated values to Serial Flash for example.

Please see examples

Best regards,
Peter
