Data & Observations
Hardware built! firmware loaded! Let's test this thing out. The video below will demonstrate the simple albeit functional SPI master and SPI slave communication.
The video should be proof enough that the SPI communication channel is working properly. The master is sending commands and the slave and the slave is receiving and displaying it on the LED output port. If you look closely the LEDs act like a binary counter, counting down to zero.
