typedef void (CALLBACK *ps4000aDataReady)

(

int16_t handle,

PICO_STATUS status,

uint32_t noOfSamples,

int16_t overflow,

void * pParameter

)

This function handles post-collection data returned by the driver after a call to

ps4000aGetValuesAsync. It is a callback function that is part of your application.

You register it with the PicoScope 4000 Series driver using

ps4000aGetValuesAsync, and the driver calls it back when the data is ready.
