ps6000StreamingReady

typedef void (CALLBACK *ps6000StreamingReady)

(

short handle,

unsigned long noOfSamples,

unsigned long startIndex,

short overflow,

unsigned long triggerAt,

short triggered,

short autoStop,

void * pParameter

)

This callback function is part of your application. You register it with the driver using

ps6000GetStreamingLatestValues, and the driver calls it back when streaming-mode

data is ready. You can then download the data using the ps6000GetValuesAsync

function.

Applicability

Streaming mode only

Arguments

handle, the handle of the device returning the samples.

noOfSamples, the number of samples to collect.

startIndex, an index to the first valid sample in the buffer. This is

the buffer that was previously passed to ps6000SetDataBuffer.

overflow, returns a set of flags that indicate whether an

overvoltage has occurred on any of the channels. It is a bit pattern

with bit 0 denoting Channel A.

triggerAt, an index to the buffer indicating the location of the

trigger point. This parameter is valid only when triggered is non-

zero.

triggered, a flag indicating whether a trigger occurred. If non-

zero, a trigger occurred at the location indicated by triggerAt.

autoStop, the flag that was set in the call to

ps6000RunStreaming.

pParameter, a void pointer passed from

ps6000GetStreamingLatestValues. The callback function can write to

this location to send any data, such as a status flag, back to the

application.

Returns

nothing
