Is there a Calibration or Configuration Tool that allows you to monitor and modify variables in an software program at run time. Basically, if you add a small piece of code to your embedded application such as CAN Calibration Protocol (CCP) or XCP you could monitor and modify the values of variables at run time. This is how the automotive world calibrates their Electronic Control Units. This is very powerful because you don't have to create a customed interface inside the embedded controller for every different application. The customization is done on the PC side from the information generated by the C Compiler. Is there a similar tool for the embedded world aside from the calibration tools for the automotive world.
I did scales once and we glued a small serial eeprom to the loadcell, so that the calibration was right if either the loadcell or the board was replaced. Erik
