Re: Python plus Picoscope 2205A on a Raspberry Pi

Hi Its not something that we have tested the picosdk-python-wrappers on but they have been tested with other Linux distro such as Ubuntu. You can download the device drivers for Raspbian Stretch from here https://www.picotech.com/downloads/linux which hopefully will let you use the python wrappers a...

Re: Problem for icdevice

Hi

For the opening the csv file, it looks like you're using the wrong function for the file type. The error says to use the fopen function instead, have you tried this?

Are you able to post some data either as a .mat file or as a graph so that I can see the noise?

Re: Problem for icdevice

Is that wanting to set the number of samples captured?
If so the sum of the preTriggerSamples and postTriggerSamples gives the total number of samples captured when using block mode (or for a single buffer when using rapid block)

Re: Problem for icdevice

Hi The filtering in PicoScope is a software feature of the PicoScope 6 rather than a hardware feature and is not contained within the API from the SDK. The 5000 series does have the switchable bandwidth limiter which is basically a filter but it set to a single value and not adjustable. MATLAB does ...

Re: Problem for icdevice

Hi The normalise function will only work for a numeric data type such as a single number or a matrix of numbers, a table is not in the possible input data types for the function so you would need to convert T from the table type to a matrix to use the normalise function from the PicoScope Support To...

After you set the peaktopeakVoltage property do you call the function to run the signal generator again?

PicoLog 6 can only have a single instance open at any one time but this instance can control multiple devices.

Re: Data Collection issue in / PicoScope 6403A / Python 2.7 / Windows 10

I've tried to reproduce what you've been seeing and have been unable to do so.

Are there any other applications running when you're doing this?
Are any other devices using the USB bus while this is running?
What are you doing with the graph each time its plotted?

Re: Can't use any python librairy

Hi Are you able to post the full code that you're using from the python-wrappers including the settings you're using for the scope? Have you checked in the programmer's guide that you're passing values that are correct for the 6407? https://www.picotech.com/download/manuals/picoscope-6000-series-pro...

Re: Data Collection issue in / PicoScope 6403A / Python 2.7 / Windows 10

What is producing the signal that you're trying to collect?
Are you able to get the capture to work in PicoScope 6 using the same settings as you're using in python?

Also what happens if you move this line
ready = ctypes.c_int16(0)
before calling runBlock?

Where exactly in the script does it fail? Do you get any error codes?
