if this is the case, does it mean XIAO ESP32C3 cannot meet the requirement of design?

Thanks for getting back to me, I couldn't find any info on support for ADC2 on the ESP32C3. If the ADC2 does not work, then it does not meet the design requirements. You can solve this problem by changing the circuit and synthesizing the POT and CV inputs with an additive circuit, but the change scale is large. Thank you!

After studying, I found that Arduino cannot modify the configuration of the ESP32 because it's pre-compiled. So, I switched to using VSCode + PlatformIO to modify the sdkconfig and resolve this issue. Although ADC2 is by default turned off in later cores, it can be forcibly enabled by modifying the configuration. If using ESP-IDF, Menuconfig can also be used to enable it.
