Part Number: AFE4490SPO2EVM
Other Parts Discussed in Thread: AFE4405EVM, AFE4405

Hi,

I would like to know if there is possible method to read AFE4490SPO2EVM & AFE4405EVM data via USB port using Python script?

And the second question is:

What is default Baud rate of AFE4490SPO2EVM & AFE4405EVM and which port is correct one?

Hi, Prabin:

Thanks for referring me to the thread. However, at the end of this thread, communication problem seems not to be resolved.
Author of that post still can't access AFE4490EVM through USB serial port.
I guess that's because he didn't get correct setting while communicating through USB port.
That is the reason why I ask about the BAUD RATE setting.

So, could you give me a correct configuration?

Hi Chang,

The baud rate for the AFE4490EVM is 230400.
The COM port of the EVM can be found in the device manager of your PC.

Hi, Prabin:

Thanks for your answer. I can access AFE490SPO2EVM via python code with the correct BAUD rate.

However, I am trying to tweak AFE4405 module at the same time. Can I have the AFE4405 communication protocol spec. ?
