M5Stack - Base - Node - Testcode

MrTarantl

Here is some testcode for everybody to get started in Platformio (Arduino)

https://github.com/captFuture/M5Stack---EnvNode

Unfortunately i could not get the i2S Dac output to work yet, maybe someone has a clue.

Hello MrT,

Any luck with getting audio up and running on the NODE?

Cheers

Sorry - not yet - i would need some help there - i have the audio libraries in place and the pins should be correct but when playing testsounds i only hear squealing noises :(

I was trying hard to get this working yesterday and used the sample from http://forum.m5stack.com/topic/143/lesson-6-1-speaker-mp3-player/2

Tried to reconfigure the dac output by changing the following according to the information here https://docs.m5stack.com/#/en/base/node_base

out = new AudioOutputI2S(0,0);
//#define I2S_WS 13 //LRCLK - Frame clock
//#define I2S_BCK 5 //BCLK - Bit clock
//#define I2S_IN 2 //DACDAT - Serial data input.
//SetPinout(int bclk, int wclk, int dout)
out->SetPinout(I2S_BCK, I2S_WS, I2S_IN);
out->SetOutputModeMono(true);
mp3 = new AudioGeneratorMP3();
playing = true;
mp3->begin(id3, out);

but no luck -> the file still got played through the internal speaker.
Maybe somebody has a clue how to proceed

Sorry, i have to give up on this. Something strange happened yesterday.
After getting quite bad sound quality out of the node module i did something else and suddenly i heard a bang, followed by a strange smell.
After unplugging and disassembling i found at least one capacitor dead in the module.

Have not decided if i salvage some parts or try to get at least the leds and the IR back into function ... currently it is just heating up when i power it.
