Ccp2 module used for both pwm and capture

[biswajitdas49]

hi everybody
i want to know that,does CCP2 module used for capture and PWM simultaneously?
Actually I want to make a device where externally driven pulse set on RB0 pin;when CCP module detect the rising edge of the RB0 pin pulse it generate a PWM pulse of very small period and then it will wait until the next external pin rising edge of the pulse not occur.i use PIC16F886.please provide me assembly code for this project.

thanks in advance!!!!!!!!

Do you need to use the CCP module for input pulse detection?

You can detect a rising edge using the external interrupt, can't you? So, you can free up the CCP2 only for PWM.

Or you can use software PWM for PWM and free up CCP2 for capture operation.

What are you doing with CCP1? If that's free, you can use that for one of the two operations.

Hope this helps.

can u tell it in more details

Which part?

You can find some examples of external interrupt here (although they use 16F877, principle is similar): https://www.edaboard.com/threads/198994/

I assume you can use the CCP module for PWM.

i assume you can use the ccp module for pwm.

i just want to use ccp1 for capture and when ccp1 interrupt is generate the ccp2 module activate and generate pwm
