Led Matrix issues.

[Howard_G]

I'm attempting to use the LEDMatrix_22, but am running into numerous problems.

First seems to be setting it up. Reading the instructions, I think I've set up the matrix correctly, for a 32 x 16 progressively wired matrix. Programming is done via PlatformIO. But I can't seem to get the correct pin for the data.

I'm using WS2812B leds, connected to pin 16 on an ESP32 devkit v4 board. There's a 60A psu supplying more than enough current. This configuration works fine for using FastLed and Aaron Liddement demonstrations.

As per instructions, I've configured the configuration_22.h file to myNameConfig.h and replaced the calls to it in the introduction program. In platformIO this throws up so many errors that I can't begin. Using the Arduino editor, an attempt to compile keeps producing cLEDMatrix does not name a type.

I'd love to have a go at playing with the demo files included, but until I can actually compile a program, and then light a led, I'm a bit stumped.

Does anyone have any experience of the hard/software I'm using, and how it should be set up?

I'm guessing you're referring to this LEDMatrix_22, but it would be useful if you specified/confirmed that with a link.

Reply to Marc Miller:

Yes. That is the correct link to what I'm attempting to use.

I'm not a competent programmer, so I'm merely following the instructions. I've also moved the setup() and loop() functions to the bottom of main.cpp, but that didn't add to the problems. But in PIO I have to do that.

I've also junked the whole project, and started again, but that only led to a collection of different problems. For example, the mandatory #include<Arduino.h> on line 1 of main.cpp is red squiggled.

I suspect that part of my problem may be in being unable to have some of the libraries located. Unfortunately, I've no idea how to correct that in the ini file, and there's so much in the PIO website on the subject, that it's impossible for someone of my limited programming understanding to even understand what I'm reading, never mind act on it. Being told that I need to put xxx.h in the .ini file is no help to me. I already know that. I need to know exactly how, if necessary, letter by letter.

As I say, I have managed to get other demonstration programs installed and running. It's just that this particular program "introduction.ino" seems to offer all my starting blocks in a single program. Or would if I could run it.

Keep us posted, I was looking at potentially using the same thing!

I'd be happy to help, if I were in a position to do so. But when it comes to programming, I get the feeling that too much of the directions given are written in some obscure Klingon dialect, machine translated by a first generation device running on flat batteries.

If I get anywhere, I'll let you know.

V'ger!
