These don't quite have the level of detail I was looking for, and are the release notes for the PicoScope application, and don't mention the drivers. It's very important that we know exactly what we're changing when we release a new driver as part of our application. For example, the two most recent...

Detailed driver change log required

Can you please set up a new forum which contains announcements about new versions of your software and drivers? In particular, it should contain a detailed change log each time a driver version changes to help us determine if we should upgrade the driver we use, or if it fixes a problem we've been s...

This was a bug in ps3000.dll. PicoTech supplied a new version, which I'm sure they've included in the latest release.

Access Violation when fast streaming

Hi, I have code that, in certain error circumstances, will call ps3000_stop from within the callback used in ps3000_get_streaming_last_values when in fast streaming mode. I then get an access violation being raised from ps3000_get_streaming_last_values. I've now changed my code to set a flag, and ca...

I've found it.

#define PS3225_MAX_TIMEBASE 18
#define PS3226_MAX_TIMEBASE 19
#define PS3425_MAX_TIMEBASE 19
#define PS3426_MAX_TIMEBASE 19

I just downloaded the SDK v1.0, and it's in there.

What is the maximum timebase for 3425?

My copy of ps3000.h in Examples doesn't have the maximum timebase for the 3425 oscilloscope. Is it 19 like the 3424 and 3423?

Same problem occurs in the streamingTests sample.

I've just run the C++ streamingTests example code, and it exhibits the same problem when using triggering. Setup: input: 100Hz sine wave into channel A, 10V amplitude. Channels: Enable channel A, AC, 20V. Trigger: Channel A, rising, level = 0, delay = 0 Sampling: 100ms, 65000 samples Open the device...

Fast Streaming and triggering

I'm trying to use fast streaming with triggering, and am finding it difficult to find much information about how it should behave. I set up the trigger, call ps3000_run_streaming_ns, then call ps3000_get_streaming_last_values in a loop. This calls into my callback until the trigger occurs. Once the ...

I think I have it...

I am capturing data from all 4 channels, at a scale of 10V, so I tried the following code, and it seems to work: public void MyCallbackIntPtr overviewBuffers, short overflow, uint triggeredAt, short triggered, short auto_stop, uint nValues) { IntPtr[] buffers = new IntPtr[8]; Marshal.Copy(overviewBu...

C# code for fast streaming?

I am trying to use fast streaming on a PicoScope 3424, but am having problems interpreting the data being passed in the callback function. My signature for the callback (passed into ps3000_get_streaming_last_values) looks like this: public void MyCallback(IntPtr overviewBuffers, short overflow, uint...
