m4 dac

estoy teniendo problemas con los dac integrados del procesador m4. alguien sabe la tasa de escritura maxima del valor analogico? mi codigo trata de un control de galvanometro a alta velocidad en funcion de una lectura de pulsos . es el sigueinte:

  1. include "mbed.h"

AnalogOut Aout (A4); InterruptIn pulso (A0, PullDown); DigitalOut led (D13); DigitalIn dir (A1 ,PullDown); float pos;

void move() {

if (dir ==1) { led =1; pos = pos+0.001; } else { pos = pos-0.001; led =0; } }

int main ()

{

while (1) { Aout.write(pos); pulso.rise(&move); if (pos>0.9) { pos=05; }

} }

thanks a lot

Adrian, which target MCU are you using? and can you format your code as indicated in the Editing Tips.

include the mbed library with this snippet

#include "mbed.h"

// your code here
