C/C++ Code
The following section includes C/C++ code for executing a high-speed
capture, as well as using RTSI to execute a high-speed capture. The
following example code is not necessarily complete, and may not compile
if copied exactly. Refer to the examples folder on the NI-Motion CD for
files that are complete and compile as is.
// Main Function
void main(void)
{
u8 boardID; // Board identification number
u8 axis; // Axis number
u16 csr = 0;// Communication status register
u16 axisStatus;// Axis status
i32 capturedPositions[6]; // Array to store the
captured positions
i32 i;
//Variables for modal error handling
u16 commandID;// The commandID of the function
u16 resourceID;// The resource ID
i32 errorCode;// Error code
///////////////////////////////
// Set the board ID
boardID = 1;
// Set the axis number
