[C6727] McASP conigurable sampling rate

Gaston Schelotto

Other Parts Discussed in Thread: ADS1178

Hello,

I'm planning to use ADS1178 + C6727 as a multichannel signal acquisition module. How could I change AFSR sampling rate from C6727 McASP?

Thanks in advance,

Gaston

Hi Gaston,

I believe what you are looking for is RMOD / XMOD. See pages 28, 92 and 106 of document:

So when you pick RMOD, the period of your FS will depend on the size of the slot - please see field RSSZ of the RFMT register page 90/91.

Of course the period of the slot will depend on the Clock - for that, please see section 2.2
