I have made good progress in my efforts to include support for the SDRPlay RSP1
in my SDR reciever application, sdrx. I still have a few issues to resolve but
it seems that I must first make data streaming from the RSP synchronous.
Unfortunately I can't proceed with just the short hint in the Mirics API
document (in the example code at the end). I am refering to the following:
// for DAB, it may be required to do all updates during NULL period,
What is this NULL period? Timing measurements I made show that data transfer
is made in short and successive bursts but with a break of about 40-50 mSec
every several transfers. Is this the NULL period?
// so once demodulator has established where this is, pass the
Any hints as to how this may be done? First sample numbers seem to increase
continuously and I don't really know how to use them.
// details to the hardware and switch to using synchronous updates
mir_sdr_SetSyncUpdatePeriod(period); // set period first
I take it that this sets the total number of samples between NULLs, the idea
being to match NULL period with the application's samples buffers?
mir_sdr_SetSyncUpdateSampleNum(sampleNum); // then set sample number at start of NULL
Don't quite understand this.

syncUpdate = 1;
...
Apologies for my ignorance but SDR is a very new concept for me

My thanks in advance!
