Re: Library for linux

Would it be possible to just get the source code?

Library for linux

Is there a Linux version of ps4000.dll ? Any way I could use those dll functions in Linux?

Thanks!

Re: RunStreaming invalid sample interval

Ya, I guess it could be block mode. It just seemed so fast I figured it was something special like streaming. Thanks!

Re: RunStreaming invalid sample interval

So it's not possible to stream at 31.25MHz? How does picoscope 6 do it? I seem to be able to stream at up to 125MHz with two channels.

Thanks!

RunStreaming invalid sample interval

Hello, I am trying to stream data from both channels of a Picoscope 4227 with version 1.1.0.288 of the dll and using Python. I try to run sampleInterval = ctypes.c_ulong() sampleInterval.value = 32 PS4000_NS = 2 ps4000RunStreaming( handle, ctypes.byref(sampleInterval), PS4000_NS, 0, 101372, 0, 1, 10...

Re: 4227 triggering a single pulse with EXT on pulse-width m

I've decided I can manage with just a normal rising trigger. But it would be a nice feature for this advanced trigger to work with EXT . Thanks!

Re: 4227 triggering a single pulse with EXT on pulse-width m

Yes, it was definitely repeatable. I'll look at it again today and see if I can provide any more hints.

4227 triggering a single pulse with EXT on pulse-width mode

Hello, This post is related to a previous one, where I managed to get pulse-width mode working with EXT but I was using a 10kHz square wave as the trigger signal: http://www.picotech.com/support/topic11977.html Now I'd like to trigger off of a single ~40us long pulse. It works fine with channel A or...

Re: 4227 advanced triggering on external input

Figured out the problem... I should have been using c_int instead of c_short. I guess it was trying to read the wrong memory segment or something. Everything works as expected now! :D

Re: 4227 advanced triggering on external input

Played with the code a bit... I think it's a problem there. I'm using Python 3.3. I think the issue is with passing the structure to the C function. Here's some pieces of code that work (ie no error) when I set trigConditions.channelA=CONDITION_TRUE, but gives a 0x22 error (PICO_CONDITIONS. One or m...

Re: 4227 advanced triggering on external input

Actually, I've figured out how to do it with the Picoscope6 software and it works fine, but I can't seem to program a pulse width trigger using the EXT input. I have a Picoscope4227. I've managed to program it using channel A as the trigger input... The programmer's guide also says that EXT input is...

4227 advanced triggering on external input

Is it possible to setup an advanced trigger using the external trigger input... like a pulse width trigger?

Thanks!

Re: Late Trigger

Here's another strange one (with the latest Picoscope6 download). Not sure how it managed to trigger. It was set to 300mV rising edge on Channel B, but doesn't look like Channel B ever made it to 300mV.

Re: Late Trigger

Thanks I'll give it a try. Why isn't that dll included in the latest Picoscope6 installation? Just curious...
