Hi,
Has anybody developed any code for programming of a Mega32 by a Mega128 via the SPI interface?
Basically, I have a Mega128 as the primary controller and 6 Mega32 slave devices that communicate via the SPI interface. The Mega128 has a separate output for each of the SS pins to the MEga32's. The Mega128 controls the common-ed reset to all Mega32's.
With the Mega128, I want to be able to read an image from the SD/MMC card and program a specific Mega32. It would be ideal if the Mega128 could read a native E-Lab HEX file and EEP file.
All of these boards are in one 19" rack enclosure.
Thanks,
Neil.
