Python support for Frequency Counting + PicoScope 4225A
4225A owner here. I've enjoyed learning how to use the PicoScope and I'm very happy that you all have built frequency counting into this model. I'm wondering however if there are any commands or ways for outputting frequency counting data using Python.
I haven't found anything in the picoscope-4000-series-a-api-programmers-guide or on the Pico Technology GitHub. So far I've been outputting frequency counter data as CSV because I don't have a good way of processing .mat files. It's been clunky however and I'd like to find a way to access that data using python.

Short google search gives below link.
So you can process the data in the file.

P.S. the counting of frequency should be done in python on the data read from the mat file.
so the number of rising / faling edges over the sample timestamps from the mat file.

Re: Python support for Frequency Counting + PicoScope 4225A
There is a function in the API to set the frequency counter although there are currently no examples to show this
Please email support@picotech.com and they will help you add this into your code.
Code: Select all
PREF0 PREF1 PICO_STATUS PREF2 PREF3 (ps4000aSetFrequencyCounter)
(
int16_t handle,
PS4000A_CHANNEL channel,
int16_t enabled,
PS4000A_FREQUENCY_COUNTER_RANGE range,
int16_t thresholdMajor,
int16_t thresholdMinor
);
typedef enum enPS4000AFrequencyCounterRange
{
PS4000A_FC_2K,
PS4000A_FC_20K,
PS4000A_FC_20,
PS4000A_FC_200,
PS4000A_FC_MAX
}PS4000A_FREQUENCY_COUNTER_RANGE;Martyn

@bennog
I should have added in my original post that the .mat files are unreadable because they seem to be corrupted. I'm already in touch with support to try and resolve this.
@Martyn
Thank you for the code. Is there a way to export data through Python? I haven't had any issues with setting the frequency counter, just getting data out of it.
