Light sensor ADC conflict

[remav]

When is used with PCM1052, I use on pin 32, the next error appear and cause a boot loop. With VS1053 same configuration is working fine.

E (484) ADC: CONFLICT! driver_ng is not allowed to be used with the legacy driver

abort() was called at PC 0x4015b3b3 on core 0

This problem results from an incompatibility between the older I2S driver and the new ADC driver included in the newer ESP IDFs.
If you not use backlight control by light sensor, simple remove "#define LIGHT_SENSOR xx" line from myoptions.h file.
But if you need it, to resolve this problem, you need to make a few changes to the display.cpp file:

1. At includes block add:

#if LIGHT_SENSOR!=255
 #include <driver/adc.h>
 #include <esp_private/sar_periph_ctrl.h>
 int8_t adcChan = -1;
#endif

2. Replace block:

#if LIGHT_SENSOR!=255
  analogSetAttenuation(ADC_0db);
#endif 

by:

#if LIGHT_SENSOR!=255
  adcChan = digitalPinToAnalogChannel(LIGHT_SENSOR);
  if(adcChan >= 0) {
    #if((LIGHT_SENSOR==36) || (LIGHT_SENSOR==39))
      sar_periph_ctrl_adc_oneshot_power_acquire();
    #endif
    adc1_config_width(ADC_WIDTH_BIT_12);
    adc1_config_channel_atten((adc1_channel_t)adcChan, ADC_ATTEN_DB_12);   // 0 - 3.3V
  }
#endif

3. Replace block:

#if LIGHT_SENSOR!=255
  if(config.store.dspon) {
    config.store.brightness = AUTOBACKLIGHT(analogRead(LIGHT_SENSOR));
    config.setBrightness();
  }
#endif

by:

#if LIGHT_SENSOR!=255
  if(config.store.dspon) {
    if(adcChan >= 0) config.store.brightness = AUTOBACKLIGHT(adc1_get_raw((adc1_channel_t)adcChan));
    config.setBrightness();
  }
#endif

Then recompile, upload and enjoy.

I'll try that and comfirm

Seems to work fine.
Thank you!!
