I didn't want to have to Calibrate the Touch Panel every time I turned on my Light Controller and I also didn't want to have to re-compile to change the data. So I wrote this routine to save calibration data in the internal EEPROM with a chack digit. If te Chack Digit Passes then it skipps the Calibration routine but if the check digit fails it rund the Calibration routine and stores the new data along with the Check Sum in the internal EEPROM. I added a Calibration button to my menu screen so the user can calibrate the TP whenever they want to.
This is a modification of the Calibration routine shipped as an example with my Easy PIC V7 development board. There is a lot of stuff to strip out if you use it in an application but it's to display the data so it's not very hard to id it.
I hope it's of use to some of you guys, it sure was worth the time for my project.

Almost exactly the same as shipped with my V& Board with the addition of the Check Sum value.

This screen I added to see what was stored in the EEPROM and if it agreed with the current data.

Verson 1.1 is much better. I uploaded way too soon. I was tired last night and didn't test very well. I added some comments and had to put delays between the EEPROM reads and writes for realiable operation, just like the library help files says (DUH).
I also reworked the Check Sum routine to actually work if the data was all Zeros or High values.
Sorry if I misslead you guys, but this version works.
