Forum Post: RE: [ Config and Start CPU-Timer of DSP TMS320F28335 ]
Hi Malory!In principle, it is not a big problem. But before configuring the timer0 it is better to get rid of any uncertainties. Let's hope that rand()-function is performed for time<<200 us. I...

Benjamin,Not directly. Are you using both CMPA and CMPB in your PWM module? If not, you could trigger you ADC conversion off of one of them. Just set one of these such that the value is...

For 12 bit resolution and 44.8kHz signal, you'll need a timer frequency of 44800*4096 = 183.500.800 Hz. Quite a bit above the specs. With below 8MHz clock, you won't get more than 7 bit resolution at...
