Description

When i want to set the setPins i get the error message

[esp32-hal-periman.c:122] perimanSetPinBus(): Invalid pin: 255 I tried to use different way's to set the value to -1 but the "perimanSetPinBus()" see the not used pins as value 255.

Sketch

#include "ESP_I2S.h"

static const int8_t NOT_A_I2SPIN = -1;

const uint8_t I2S_SCK = 19;
const uint8_t I2S_WS = 33;
const uint8_t I2S_DIN = 23;
const uint8_t I2S_DOUT = 22;

I2SClass i2s;

void setup() {
  Serial.begin(115200);
  while (!Serial) {
    delay(10);
  }

  i2s.setPins(I2S_SCK, I2S_WS, I2S_DOUT, NOT_A_I2SPIN, NOT_A_I2SPIN);
  if (!i2s.begin(I2S_MODE_STD, 16000, I2S_DATA_BIT_WIDTH_16BIT, I2S_SLOT_MODE_MONO, I2S_STD_SLOT_RIGHT)) {
        Serial.println("Failed to initialize I2S Speaker bus!");
        return;
    }
}

void loop() {}

I don't have a PICO-D4 to test on, but I am unable to reproduce on standard esp32. Please set core debug level to verbose and post the log (the stuff in setup anyhow) . In the future, please post minimal code that can be copy/pasted so we can be running exactly the same code you are.

I updated the sketch a little bit. So you can now test it as is. Sadly i tried the script above and i can't reproduce it as well. I tried to follow the steps from my own sketch and that did not resulted in the above error as well. So there must be something else going one.

The issue is also shown on different devices. It looks as if an int8_t is pressed into a uint8_t making the -1 into a 255;

As i said above, i cant reproduce using the script above as well. I'm going to look further until i can reproduce it. When you have any suggestion on how to search for the issue all input is welcome. The error message does not tell which pin has the "255" value.

Anyway thanks for trying to reproduce the error. I will comeback to this soon.

I am closing this issue as it's solved in the latest versions. Was not able to reproduce with 3.1.1.
