I've got a Motorola MC68HC11E1 microcontroler with a small program on it. What I need to do is write a GUI interface to upload config data to certain memory locations and download stored data from other memory locations. I can do serial I/O in MFC but I need to know how to read/write to memory locations on the Microcontroler through the Serial Communications Interface. Even more basically will the MCU do this or do the upload/download routines need to be written into the onboard program?
Answers, references, suggestions, and/or comments appreciated.
