Max7219 display - help
We have a customer that asked about using the Max7219 display with the Parallax Propeller P1.
When the unit is turned on all 64 leds lock on to max brightness .. no codes sent to the unit dislodge this .. the only way to reset it is to disconnect vcc
I don't one of these modules yet.... is there anyone that has tried this module ?
Any advice on how it should behave ?
Thank you !!
Edit: microcontroller was originally stated as P2, whereas the customer is working with the P1.
