[SOLVED] ISCP programming with radio attached
I got feedback for my project that programming via ICSP is not possible with the RFM69 radio attached. Since it is basically SPI, I don't really see a reason for that. Can anybody explain that? Do I need to pull CS for the radio high, maybe, or is there something deeper to it?
yes, in general, a good practice for SPI is to use a pullup for CS, preventing unattended behaviour.
Problem solved with pull-up! Thanks!
