Hi.
I'm (trying) to design a CANbus node for my home automation project. Any given node consist of a main-board with a power supply circuit, a PIC18F26K80 and a demultiplexer to handle the chip select of up to 8 daughter boards.
A daughter board will at have a (small) PIC running in SPI slave mode. The main board will thus be the SPI master.
It would be nice to have the ability to change the program in the PIC of a daughter board remotely. Is it possible for the SPI master to alter the program code in the slave with just the SCLK, MOSI, MISO and SS lines connected or do I need something more ?
Best regards
Henning
