This will effectively increment a 32 bit unsigned value.
When both words contain the values you want, just send to the MAX7219 one after the other as a 32 bit value.
Once you set the pin to output, the digital/analog mode setting doesn't really matter.
You can output a 1 or 0 with the pin still in analog mode. All that bit does is turn off the digital input...
Ok so I have portb I think configured correctly where RB0 through RB6 are configured as digital for use with my jumpers to control the distance and timing. I will read low if the jumper is connected...
Aaaahhh ok I see that now on page 133 for PBADEN (reset, power on) and notes for PORTB on page 148 for ANSELB
I'm skipping over some reading and that's not good I need to review closer, I'd print...
Also, most of the PORTB pins are dual analog/digital pins. You have to set them to digital mode otherwise they always read '0'.
Either set ANSELB bits = 0 for the ones you want to be digital, or set...
