main program to test dac57xx library

Hi Daniel:

I have imported your library for AD5754R and it is very nicely organised into a class. Great work. You have said in your comments in the code that you have tested the library with AD5754R. I have a lot of difficulty past few days to get it going. Could you please provide me with a code example (main program) that worked for you? Any documentation or any help or diagram is appreciated.

Looking forward to hear your help

Ras

Oh by the way, here is my sample code:

  1. include "mbed.h"
  2. include "dac57xx.h"

Create and instance of the SPI class SPI AD5754R(p5, p6, p7); MOSI, MISO, SCLK

Pin Configuration to DAC Serial pc(USBTX, USBRX); DigitalOut BIN2COMP(p21); DigitalOut CLEARPIN(p22); DigitalOut LDAC(p23); DigitalOut SYNCH(p24);

DacAD57XX AD5754R(p5, p6, p7, p24);

uint32_t answerIN; unsigned int answerOUT;

int main() {

LDAC = 0; CLEARPIN = 1; pc.printf("Started!\n\r"); while(1){ AD5754R.setOutputRange(AD5754R.ADDRESS_A, AD5754R.BIPOLAR_10V); AD5754R.setPowerControl(31); answerIN = AD5754R.getOutputRange(AD5754R.ADDRESS_A);

pc.printf(" %u \n\r", answerIN); wait_us(1000000); } }

and what i get is 0x480000 ALL THE TIME!
