Examples
The example files below are installed with the TDT drivers package.
Files: C:\TDT\RPvdsEx\Examples\PO8e\PO8eTest.rcx, PO8eTest.exe, PO8e.h
Hardware: RZ2 Real-Time Processor
Overview: PO8eTest.exe connects to any PO8e card(s) in the PC, waits for a
stream then displays the data rate that each PO8e card is receiving. PO8eTest.rcx
streams 256 channels of floats to the PO8e card at 6.1 kHz. Launch PO8eTest.exe
first, run the circuit and then set the zBusA trigger high to begin streaming.
PO8e Streaming Interface for the RZ
Size of each data sample in bytes.
This code determines how many bytes are in each sample.
int size = card->dataSampleSize();
int size = dataSampleSize(card);
This returns the most recent error.
int getLastError();
int getLastError(void* card);
The most recent error code.
This code determines how many channels are in the current
stream.
int nChannels = card->getLastError();
int nChannels = getLastError(card);
