ESP-WROOM-32 ADC0 & ADC3
ESP-WROOM-32 ADC0 & ADC3
Can ADC0 and ADC3 be used on the ESP-WROOM-32, since those pins are internally connected via 270 pF caps to the SENSOR_CAPP and SENSOR_CAPPN pins on the ESP32? I read that the 12-bit conversion time of the ADC is about 166 us, is the conversion time reduced on those two pins due to the caps? Thanks.
Re: ESP-WROOM-32 ADC0 & ADC3
I'm looking for the same information. If we weren't cutting it close on I/O for the design, I'd just use other pins. I'm wondering whether the ROVER with the integrated 270pF capacitors on SENSOR_VP and SENSOR_VN can perform normal ADC operations on these two pins.
Thanks!
Thanks!
