Change Setting of OPENADC

[Magnolia]

Hi,

I have some questions in changing the settings of CW-Lite for better capturing,

1. I look into the API files and find that scope.gain is able to amplifier the value of the traces(maybe). And I change the default setting of scope.gain to scope.gain.db = 50 but it seems to have no differences to scope.gain.db = 25.

2. I want to have a better sampling precision and I see here ADC Spec and the traces and find saying:

@Alex_Dewar

It’s more correct to say the max sample rate of the Lite is 105MS/s - depending on the ADC clock, this might be (and is for the default examples, which capture at 7.37MHz * 4) less. If you want to see the sample rate, you can check scope.clock.adc_freq .

So, I check the default setting, it shows that

which is different to the information shown in API pages.

And I try to change the scope.clock.adc_src = "clkgen_x4 it returns read time error in my well working project. I don’t know where I should change as well for a better sampling.

1- Is the target doing the same thing for both measurements? Which firmware is it running? From your other threads I remember you having some problems with capturing and triggering with your own firmware.

2- Can you show me the error, the Python code you’re running, and the output of scope.clock after the error occurs?
