csr8670, I want to pass a string of data received in the VM program to
the internal of the DSP for processing, here I refer to the official DSP
routine provided, my_frist_dsp_app, the application is to pass the ADC
data to the DSP for processing, using stream connect, the form of the
stream for transmission, the official SDK on stream is introduced using
StreamRegionSource(), which can be used as a source for a section of
memory and then passed to the DSP in the form of a stream.
1 | uint32 ir_buffer[24] = {1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6};
|
2 | Source ppg_source_ir = StreamRegionSource( (uint8 *)ir_buffer, 24 );
|
3 | PanicFalse( StreamConnect(ppg_source_ir, StreamKalimbaSink(2)) );//Here the source is associated with port2 of the dsp
|
But when I actually tested it, I found that the data in ir_buffer will
not be passed to DSP in DSP, so please ask if there is anyone who has
done this kind of data transfer？
