[quote user="Bruce McKenney47378"]1) Are you watching the STROBE1 pin with a scope or an LED?[/quote]
I'm watching the STROBE1 pin with a scope. With it, it is clear that the code is not going into the ISR properly.
[quote user="Bruce McKenney47378"]2) Are byte_count and Temp_SPI_Read declared "volatile"?[/quote]
Temp_SPI_Read is volatile, but byte_count is not. I understand why the Temp_SPI_Read should be volatile (since it is holding the information to go into different states). I assumed that since byte_count is just a counter, there was no need. I'll try changing it once I'm in front of my code again.
