'CP210x USB to serial driver (v11.1.0) for Windows 10/11' Install failing

[denko 2]

Hi,
There is an error when I install the 'CP210x USB to serial driver (v11.1.0) for Windows 10/11'.
My operation system is win11, KB5026368, updated in 2023.5.9.

1. I tried to install it by right click, but there was no response.

2. I then installed it in the device manager, and it showed install successfully but:
   

Could you please help me to deal with it?

Sincerely
Denko

Hi @denko-2

In CP210x_Universal_Windows_Driver_ReleaseNotes.txt you find the manual install instructions.
Did you follow these?

1. Using Windows File Explorer, locate the driver folder
   (that you previously unzipped)
2. Right click on the silabser.inf file and select Install
3. Follow the instructions

This worked for me in my windows 10 pc.

@CamilaSouza
Thanks a lot!
It works today, really strange....

Could I ask another question that I find the code in example is for pcm digital mic, how can I find the related one for PDM digital mic?

@denko-2

I guess the "PCM digital mic" means Analog mic we are saying.
So this question is just like "how to use digital mic on spresense?"

Please check below document.

To use digital(PDM) mic, some soldering is needed.

ic, some soldering

Thanks, CamilaSouza.

I have connected the PDM mic.
This is my first project about audio signals; I would appreciate your answers.
I want to confirm whether the example 'pcm capture' captures the data from a PDM mic and demodulates the signal. This means that we can process the data directly. In other words,
Is there any step I need to do before processing the data from 'pcm capture'?

Thanks a lot for your answer again.

Hey, @denko-2

Yes, that is correct

Sorry for the delay.

@denko-2
Also, take a look at the Signal Processing examples on Arduino.
They might help
