Detailed Description

The DsoService class accesses the DSO (Digital Storage Oscilloscope) service of Pokit devices.

Definition at line 23 of file dsoservice.h.

Member Typedef Documentation

◆ Samples

typedef QVector<qint16> DsoService::Samples

Raw samples from the Reading characteristic.

These raw samples are (supposedly) within the range -2048 to +2047, and need to be multiplied by the Metadata::scale value from the Metadata characteristic to get the true values.

Also supposedly, there should be no more than 10 samples at a time, according to Pokit's current API docs. There is not artificial limitation imposed by QtPokit, so devices may begin batching more samples in future.

Definition at line 94 of file dsoservice.h.

This is just a convenience function equivalent to calling setSettings() with the command set to DsoService::Command::Refresh.

Once the Pokit device has processed this request successfully, the device will begin notifying the Metadata and Reading characteristic, resulting in emits of metadataRead and samplesRead respectively.

196{
197 // Note, only the Settings::command member need be set, since the others are all ignored by the
198 // Pokit device when the command is Refresh. However, we still explicitly initialise all other
199 // members just to ensure we're never exposing uninitialised RAM to an external device.

◆ metadata()

DsoService::Metadata DsoService::metadata ( ) const

Returns the most recent value of the DSO service's Metadata characteristic.

The returned value, if any, is from the underlying Bluetooth stack's cache. If no such value is currently available (ie the serviceDetailsDiscovered signal has not been emitted yet), then the returned DsoService::Metadata::scale member will be a quiet NaN, which can be checked like:

const DsoService::Metadata metadata = multimeterService->metadata();
if (qIsNaN(metadata.scale)) {
// Handle failure.
