I have the boards from the Circuit Note 429 and I am trying to set the voltage bias on one of the boards to -600mV.
When using the command: "setvbias -600", the response is "Sensor bias set to -600 mV". However, using the "ReadConfigs" command, the Vbias is now set to -88mV.
Using trial and error, the minimum reliable negative setting is -128mV.
Is this the lowest limit of the bias setting?
Unfortunately, I wasn't able to reproduce the error you're experiencing. Have you done any modifications to the firmware on the CN0429 sensor board or the ADICUP3029, or are you using the default setup?
Can you share some screenshots of the terminal window?
Thank you for the response. I apologise for the delay from me; I did not have the email notification setting enabled and missed your reply.
I can confirm that I have not made any changes to the default setup.
I will setup the boards again today and take the screen shots you requested.
