What is the expected behavior?

I tried to run the adc continuous mode example from esp-idf examples making necessary GPIO changes to suit P4. It should continuously read adc samples using the API function adc_continuous_read().

What is the actual behavior?

The function adc_continuous_read() returns values for exactly 1 buffer length (whatever the frame size is. I'm using frame size = 256, so it reads 256 values) and then continuously returns ESP_ERR_TIMEOUT after that. Also, the adc raw values are not accurate. I expect the data to be '0' when the adc input pin is grounded. But it reads values around '280' - '290'.

Steps to reproduce.

This is the code I'm using:

/* Initializtion Function */
void adc_init(adc_continuous_handle_t *out_handle)
{
    adc_unit_t adc_unit_num;
    adc_channel_t adc_channel;
    adc_continuous_handle_t adc_handle = NULL;

    adc_continuous_handle_cfg_t handle_config = {
        .max_store_buf_size = ADC_MAX_BUFFER_SIZE, // size = 2048
        .conv_frame_size = ADC_FRAME_SIZE, // 256
    };

    ESP_ERROR_CHECK(adc_continuous_new_handle(&handle_config, &adc_handle));

    adc_continuous_io_to_channel(ADC_GPIO_NUM, &adc_unit_num, &adc_channel);

/* Need to configure pattern struct as per below for each channel being used
Currently using only 1 channel */

    adc_digi_pattern_config_t adc_pattern_config = {
        .atten = ADC_ATTEN, // 0dB
        .bit_width = ADC_RESOLUTION, // 12 bits
        .channel = adc_channel,
        .unit = adc_unit_num,
    };

    adc_continuous_config_t adc_config = {
        .pattern_num = NUM_OF_ADC_CHANNELS,
        .adc_pattern = &adc_pattern_config,
        .sample_freq_hz = ADC_SAMPLE_FREQ, // 48kHz
        .conv_mode = ADC_CONVERSION_MODE, // Only ADC 1
        .format = ADC_CONVERSION_FORMAT, // Type 2
    };

    adc_continuous_config(adc_handle, &adc_config);
    *out_handle = adc_handle;
}`

uint32_t ret_num = 0;
static TaskHandle_t s_task_handle;
uint8_t adc_buf[ADC_FRAME_SIZE];  // Frame size = 256

static bool IRAM_ATTR s_conv_done_cb(adc_continuous_handle_t handle, const adc_continuous_evt_data_t *edata, void *user_data)
{
    BaseType_t mustYield = pdFALSE;
    //Notify that ADC continuous driver has done enough number of conversions
    vTaskNotifyGiveFromISR(s_task_handle, &mustYield);

    return (mustYield == pdTRUE);
}

void capture_task(void * parameter){
s_task_handle = xTaskGetCurrentTaskHandle();
adc_init(&adc_handle);
adc_continuous_evt_cbs_t cbs = {
        .on_conv_done = s_conv_done_cb,
 };

ESP_ERROR_CHECK(adc_continuous_register_event_callbacks(adc_handle, &cbs, NULL));

ESP_ERROR_CHECK(adc_continuous_start(adc_handle));

while(1){
  ulTaskNotifyTake(pdTRUE, portMAX_DELAY);
  while(1) {
          esp_err_t ret = adc_continuous_read(adc_handle, adc_buf, ADC_FRAME_SIZE, &ret_num, 0UL);
          if(ret == ESP_OK) {
              for (i = 0; i < ret_num; i += SOC_ADC_DIGI_RESULT_BYTES) {
                  adc_digi_output_data_t *p = (adc_digi_output_data_t*) &audio_adc_buf[i];
                  ESP_LOGI(TAG, "ADC_Value: %d, Channel:%d, i%d:", p->type2.data, p->type2.channel, i);
              }
              //vTaskDelay(1);
          }
          else if (ret == ESP_ERR_TIMEOUT) {
              break;
          }
    }
}
}
