Subject: [SPAM] [piclist] pic24h SPI Problem
Hello again,
I think I've exhausted myself over this one. SPI is supposed to be REALLY
simple, right? But, I can not get my SPI slave (PIC24) to do even recognize
that SPI is happening at all.
I always do a simple loop-back test if I have problems, and also use a
little PCB I've made with a 74HC595 and eight LEDs driven from the outputs.
The 'HC595 is SPI-compatible. Once I've established that the device is
transmitting and receiving properly, I can then find out why the other end
isn't working.
Leon
