Now I design a meter. In order to input 0,1,2,...,9 ten digital, I want to use rotary encoder .

But I have no idea about how rotary encoder interface f28335?

Any advice is welcome.

use eQEP?

Henry,

The eQEP module is the correct module for interfacing a rotary encoder. You can find more information about the QEP in the eQEP Reference Guide:

http://focus.ti.com/lit/ug/sprug05a/sprug05a.pdf

Also, there are 2 QEP example codes provided with the C2833x/C2823x C/C++ Header Files and Peripheral Examples that can help get you started:

How to interface an absolute encoder with TMS 320F 28335. I guess eQEP module can be used for incremental encoder only.

Avinash,

What absolute encoder interface are you looking to implement?

Most absolute encoder interfaces can be done with the C2000's SPI and (perhaps) some external logic.

In particular, a SSI interface should be relatively easy to implement and require very little external circuitry.

Thank you,
