PulseBlaster
Example Use of C Functions
/*
* PulseBlaster example 1
* This program will cause the outputs to turn on and off with a period
* of 400ms
*/
#include <stdio.h>
#define PB24
#include "spinapi.h"
int main(){
int start, status;
printf ("Using spinapi library version %s\n", pb_get_version());
if(pb_init() != 0) {

// Instruction 0 - Continue to instruction 1 in 100ms
// Flags = 0xFFFFFF, OPCODE = CONTINUE

// Instruction 1 - Continue to instruction 2 in 100ms
// Flags = 0x0, OPCODE = CONTINUE

// Instruction 2 - Branch to "start" (Instruction 0) in 100ms
// 0x0, OPCODE = BRANCH, Target = start
pb_inst(0x0, BRANCH, start, 100.0*ms);

// Trigger the pulse program
pb_start();
//Read the status register

}
A more complex program using C Functions is provided in Appendix II.
