Dear Grozomah (and everyone on this post),

I have tried to use your code but have been unsuccessful in getting output that makes sense. The only changes that I have made to your code is changing the trigger_voltage variable. Currently I am testing the code by using a function generator but the code is "collecting data" at seemingly wrong values. For example, I set trigger_voltage to 1V and the code triggers at some value less than 1V. Could you also explain what you mean by "[1V...~600 RP units]"?

Sorry for my lack of understanding and probably vague question but I am a complete novice when it comes to the Red Pitaya.

I want to thank Grozomah and trollhassel for their source code.
They work very well for my application.

Hi,

after the successful test of posted codes, my next attempt is to add also decimation 2 and to transfer data as uint16 instead of uint32.

:) i bought it ! Very sexy little machine ! ... however ,

... attempting to discover this "triggered high speed acquisition" program, the compilation phase refused to give me an executable and i wonder why : this is the error message copied from the console...

i had everything cloned from the git repository and this should have worked ?... apparently some links have been lost before the compilation.
Question : what should i have done?
Should i import some other things into the examples directory before the compilation?
Is there a specific FPGA image i should have setup before compiling?...

Did anybody experienced this before me? can you help me?

kindest regards,

mbr
