Hello!

Yes 8bit + Pseudo Random Bit Signal of values either 0x00, 0x01, 0x0F. any comment of Espressif Techs would be fine here!

maybe its fixable inside esp-idf adc driver,

Hello! The issue is present up latest esp-idf v5.3, i am still testing new releases. a statement from Espressif would be HELPFUL! I already contacted their support and never got a response. i am pretty sure they are aware of this bug. So if anybody can help us fix this issue it would be really aprec...

No it does not, it is an old analog one - i can also verify it with specific mV values from a super exact Aim-TTi EX354RD presented to the ADC Pin.

Thanx

Hello!

I seems not to be from timing. Both CPUs run from 160Mhz. Also if i sample the slope with adc cont. driver with 82kHz i never get any digital delta values (new adc value - last adc value) of 2,3,4,5,6,7,8,9,10,11,12,13,14 - only 1,15,16,17

This seems pur ADC problem.

best regards

Hello! 1Hz is the slowest i can do with my Function Generator. I get the same ADC jumps of Value also when i sample with ADC Continuous Mode Driver. There is never any 2,3,4,5,6,7,8,9,10,11,12,13,14 values. Only 1,15,16,17 and combinations of the last ones. https://docs.espressif.com/projects/esp-id...

Hello! Using latest esp-idf v5.2.1 a little test program which runs either on ESP32-C3 OR ESP32-C6 shows that the ESP32-C6 SAR ADC gives less accurate ADC readings - could we please fix this somehow in esp-idf ? The same problem is existing with the adc-oneshot driver. attached are two value files o...
