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

Raw samples from the Reading characteristic.

These raw samples are (supposedly) wihtin the range -2048 to +2047, and need to be multiplied by the Metadata::scale value from the Metadata characteristc 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.

◆ fetchSamples()

bool DsoService::fetchSamples ( )

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 succesffully, the device will begin notifying the Metadata and Reading characteristic, resulting in emits of metadataRead and samplesRead respectively.

Definition at line 204 of file dsoservice.cpp.

205{
206 // Note, only the Settings::command member need be set, since the others are all ignored by the
207 // Pokit device when the command is Refresh. However, we still explicitly initialise all other
208 // members just to ensure we're never exposing uninitialised RAM to an external device.
