Status on CCP pin in capture mode

hiep truong

Hi, every body.

I am using stellaris launchpad for reading quadrant encoder. There is not QEI module in LM4F120 so I want to use Input-edge mode of timer0 for capturing both of the edges of a channel from the encoder.

Can you show me how to read status of T0CCP0 (PB6) pin in input-edge mode?

Thank you.

You can try to read GPIO part B GPIODATA register and obtain the state of PB6 pin.

Let me know if it works for you.

Thank you so much.

The status of TnCCPx pins can be read from GIPODATA register. It works perfectly.

Best Regards.
