The drawback to this is a lack of efficiency, as directly manipulating the target memory and manually verifying data takes significant time on the CAN bus.

To make the operation more efficient, the programming target could be given some intelligence, like selfverification.

This would make communications unidirectional, essentially cutting the time on the CAN bus in half.

Overall, the best savi

AN247 Features

* built into Microchip’s Enhanced FLASH Microcontroller devices is the capability of the program memory to self-program. This very useful feature has been deliberately included to give the user the ability to perform bootloading operations. Devices like the PIC18F458 are designed with a designated “bo
