Doesn't work on NodeMCE-esp32

[danewber]

I'm trying to use this on a Nodemcu-esp32. I have been very successful on an mh-et live minikit. None of the demos will run on the nodemcu. I have tried 2 different models (probably knockoffs but not the point). The code stops after the "i2s_parallel_setup_without_malloc" function. I uncommented the "printf("i2s setup done");" line and it displays in serial output. I'm still trying to figure out where it stops.

It is definitely stopping during the "matrix.begin()" function.

For additional context, I'm using the "Feature Demo". I've added output like the following: `
// initialize the digital pin as an output. pinMode(ledPin, OUTPUT);

Serial.begin(115200);

printf("Adding background layer\n"); matrix.addLayer(&backgroundLayer); printf("Adding scrolling layer\n"); matrix.addLayer(&scrollingLayer); printf("Adding indexed layer\n"); matrix.addLayer(&indexedLayer); printf("Layers Added"); matrix.begin();

printf("Matrix Begun"); `

The output looks like this:

[danewber]

The last line "Made it through the begin function" is output I added in SmartMatrixMultiplexedCalcEsp32_Impl.h at line 337

It just stops after this and does nothing else. Note the "Matrix Begun" line is never output.
