Deprecated i2s_read_bytes function

[abaokbah]

Hi,

I tried to run the project on an older version of Arduino IDE and it works fine. However, when tried on the latest version, it throws back an error saying i2s_read_bytes isn't defined in the scope. When I did some troubleshooting, I discovered i2s_read_bytes has been deprecated and replaces with i2s_read.

The problem I'm having is a "too few arguments" whenever the verification reaches the i2s_read function. I looked up the function definition and it has an extra parameter (size_t *bytes_read) compared to i2s_read_bytes. I'm not sure what should go in there?

Any help would be greatly appreciated

Regards, Ali

Not sure if it was solved.

you would help a lot if you rewrote using the new i2s_read method

[Geethukulal]

int I2S_Read(char *data, int numData)
{
size_t bytes_read;
return i2s_read(I2S_NUM_0, (char *)data, numData, &bytes_read, portMAX_DELAY);
}

Use this function

[DansDesigns]

int I2S_Read(char *data, int numData) { size_t bytes_read; return i2s_read(I2S_NUM_0, (char *)data, numData, &bytes_read, portMAX_DELAY); }

i can confirm this allows the sketch to compile, along with the following changes to the I2S_Write function below the I2S_Read:

int` I2S_Write(char *data, int numData) { size_t bytes_write; return i2s_write(I2S_NUM_0, (char *)data, numData, &bytes_write, portMAX_DELAY); }

and in I2S.h, last line change from:
void I2S_WRITE
to:
int I2S_WRITE

EDIT: also found needed to add:
pin_config.mck_io_num = GPIO_NUM_0;
to I2S.cpp
within:
if (MODE == I2S_MODE_RX || MODE == I2S_MODE_TX) {
