Hi everyone,I am using the STM32C011J4M6 in the SO8N package.I want to use the ADC on a low frequency signal (around 1kHz). My application needs to be very low power so I decided to put a big (around 100kOhms) input resistance on the ADC pin like we ...

Hello everyone,I have a question about the STM32C011J4M6 in S08N package.I am developping a PCB with this MCU and want to use an LSE like in the picture below.Then I also want to program and debug my MCU with an stlinkv3 and will use the SWD debug so...

Yes I think I will put a 25kOhms resistance, I can deal with µA.It is the voltage across a stator phase, I want to measure the speed of a generator. But the generator is really small so I don't want to consume too much current.

I agree with you, the energy will be the same but the current spike lower if we increase the charging time. And the only way to increase the charging time here, is to increase the input resistance.To be more precise about my application, I don't need...

I put a big resistor to increase the charging capacitor time (T=RC), so the current to charge the 5pF capacitor will be lowered.

Okay, thanks Pierre_P for your answer.I think I will do the second option and use a 0 ohm resistor.Correct me if I am wrong, SWCLK is also used to flash the program not only for debugging ?Best regards,

Ok thank you for your answer.Do you know what is the default function of the pin ? I suppose the PA14 for SWCLK ?If it is the case, after flashing my program, how do I switch to the OSCX_OUT function ?
