Ok, so for example I want to send 3 300us wide pulses(12v) with a gap (0v) of 700us every 10ms. Do you have any c/c++ sample program that can demonstrate that? Ideally the program would read an TXT file that I could specify the specs of the waveform and have the picoscope do that. the text file woul...

Mark, Thanks for your input. I had figured out by trial and terror that changing the denominator will significantly improve the ability of streaming tests to collect my samples without dropping any data. This is a very useful tool for environment testing to be able to collect long samples of data at...

ok I got a workaround to the missing data, but I don't know why it works.


If I set the denominator to 10, then I don't drop any data for the 5 seconds.

What is the denominator setting for?

If you ask me, we strip it out. I don't want any of the GUI stuff. All I want is the data. As you can see in my version of streamingtests.cpp, I just dump the 5,000,000 element array to an ASCII file, (BTW, if you get rid of my goofy graph the sample data file reduces to 90MB. Quite a bit of savings...

today I tried to compile and link the program in release mode hoping that maybe the debug mode and its inherent slower operation were causing the loss of data. No such luck. the release version shows the same loss of signal. I also notice that while I am collecting 5 seconds worth of data, the GUI s...

OK, here's my latest. I collect with streamingtest 5,000,000 samples. The sampling seems to start just fine: http://jleslie48.com/picoscope/streamingtest_070314_01.jpg note the red acknowledgement of data. But then it seems to drop out: http://jleslie48.com/picoscope/streamingtest_070314_02.jpg But ...

ok heres my backup:

start with the readme file.

hopefully we can move this forward.

Sincerely,

Ok, I can build and run streamingtests.cpp now under Windows_XP. the final step was replacing the function description to: void __stdcall StreamingGetOverviewBuffersMaxMin ( short **overviewBuffers, short overflow, unsigned long triggeredAt, short triggered, short auto_stop, unsigned long nValues); ...

ok I re-analiyzed my run and collect_fast_streaming is NOT collecting any data. the data I was looking at is left over from the previous 'B' command. I am hitting the stub though, on the second pass of the 'L' option, why isn't the stub occuring on the first pass? Although the program crashes on the...

Sarah, I think I'm a litter farther along than you, so I packed up my work to date, hope it helps. heres what I have so far: http://jleslie48.com/picoscope/picoscope_070305.zip if you unpack it, it makes a directory "C:\jon\c\source\..." I was able to get streamingtest to build and run on Visual C++...

please join the discussion over here:

we're trying to work it out right now.

the examples file is not complete. there really needs to be much more extensive directions on how to build and run the examples. It took me nearly half a day to realize that the examples require visual C++ 8.0, why this isn't listed as a pre-requisite is beyond my understanding. I'm fighting with th...

heres my session showing the makefile I've tried to use: C:\jon\c\source\PS3000> type ps3000con._i_ # Borland 5.5 ps3000con mode makefile for CONSOLE [Win32] # # To use: "make -f ps3000con._i_" # CCFLAGS = -c -DWIN32 ps3000con.exe: ps3000con.obj ilink32 -Tpe -ap -c c0x32 ps3000con ps3000con,ps3000co...

Well I want to try out the program ps2000.c in: C:\Program Files\Pico Technology\Pico Full\Examples\PS2000 but I look at the source and it references,(from ps2000.c): . . . #include "ps2000.rch" . . . which is not there (from command prompt): Volume in drive C has no label. Volume Serial Number is 5...
