Hi all,
In the ESP-IDF docs at https://docs.espressif.com/projects/esp ... s/adc.html it says "There are currently three sources of calibration values. The availability of these calibration values will depend on the type and production date of the ESP32 chip/module." but I have not been able to find any additional information about this. Two questions, then:
1. Does anyone know which modules, versions, dates, etc. will have their ADCs factory calibrated?
2. Is there any way to specifically order or guarantee that we'll receive modules that have been calibrated?
Thanks,
Jason
ADC Calibration Factory Fuses?
Re: ADC Calibration Factory Fuses?
Following. I've switched to an i2c adc due to the issues with the esp32 adc. Would love to switch back to using the esp32 adc if the calibration brings the accuracy and error down to a reasonable level.
