Waveforms SDK - SPI Baud rate calculation

[Timotej Merklin]

Hi,

I am using the Analog Discovery 2 and the Waveforms SDK in python.

I want to create a function which gets/calculates the baudrate from the clock.

At the moment this in my config:

• set trigger to CLK
• Divider: -1
• Sample format: 8
• Trigger Position set: -1
• Use the "FDwfDigitalInStatusTime" to get the device time
• acqmodeRecord

I have also tried singleshot mode and to put the divider at 1

I am having problems as I see the function getting the devices time only gets the time from one trigger, even though the data pulled is from multiple triggers of the clock.

 

I would like to get the time of the first clock trigger and the second one. With this I could calculate the baudrate.

Hi @Timotej Merklin

Perform a single capture and process the data.

Hi @attila

I tried doing a single capture but looks like I am getting some errors when capturing data.

Perhaps I am configuring something wrong, I am guessing I should just be able to configure the BufferSize, TriggerSet, start the capture and then get the data with DigitalInStatusData.

Could you point me in the right direction if I am missing something?
