Troubleshooting #3

Open department-g33k opened 3 years ago

department-g33k commented 3 years ago

I'm not terribly proficient in C#, and I'm having great difficult troubleshooting this (I'm building the display for my son).

When I connect my StackMat to the arduino and run a timing cycle, I get no output on the LED matrix. I've verified that the sleeve of the 3-pin connector to the stackmat is going to GND on the arduino, and that the tip is connected to D2.

I can verify that my LEDs and MD_Parola are working properly using their example code.

I see many "Serial.println()" functions, but I can't tell if I should be seeing the corresponding output in the Arduino serial monitor, or if those are used as part of the communication with the timer.

Frankly I'm lost as to how I might find out if my issue is on the display side, or that the MCU isn't detecting the timing signals from the Stackmat.

Any suggestions?

Hello! Github isn't notifying me about issues so I just saw this. I do apologize for the terrible state of the code, I would definitely do it very differently if I was doing it today. Unfortunately, I no longer have the hardware with me so I can't help you out too much with debugging this.

I was about to suggest using the Software Serial library with inverted logic instead of all the messy hardcoded decoding, but it looks like you've figured that out yourself. I actually tried that years ago, but the performance with my existing code seemed to be better. How is your setup working right now?
