I think Sigma Delta is not supported by SX micros. Do you have information?

Joe

Hi,


I think Sigma Delta function is not suported by SX micros.

Perhaps you will need to use other micros.

Do you have more informatiomn?

The SX's use Sigma-Delta to do their analog to digital and digital to analog conversions. The Propeller uses Sigma-Delta as well for the same purpose.

Joe

Thanks,

do you know about information (PDF ) to read and understand
about SX and the Sigma Delta ?

Thanks, JOe

Joe,

I am not sure what you mean by sigma delta. Are you asking if the SX can perform a sigma delta A/D conversion? This requires a comparator and an integrating D/A converter. The SX48 has a comparator, and the integrating D/A converter could be made from an output pin and an RC circuit.

Hi , Dave

I think that SX could help , but I can not find information
about sigma delta using SX micros.

For this reason I am looking for PDFs.


If you know about how can I use a SX micro and use
Sigma Delta please tell me where can I find the PDFs.

( My english is not good, sorry)

Thanks, Joe

Joe,
Are you wanting to do analog to digital conversion ? If yes, then look at this web page:

Hello Joe;

Also look at the Parallax website under SX Chips and Tools; the Download section has lots of good app notes, and the sigma delta A/D application is covered there.

Cheers,
