ok, ok....

the code was:
CCP_PWM_L_L

The correct is:
CCP_PWM_H_H

Now this correct, thank you PCM programmer and Ttelmah.

The diagram in page 153 says it all.

Hi all,

I´m using a PIC18F4550 and half bridge config. As the MOSFET need a time to take off, I need config the dead-band or the MOSFET´s enter into shortcurt.

When the change PDC6~PDC0 in ECC ...

I got 155ksps.

I don� understand why my code only execute the interrupt.

The exemple:

#include
#device adc=10
#fuses HS,NOWDT,NOPROTECT,BROWNOUT,PUT,NOLVP
#use delay(clock=20000000) ...

Ok

I tested in my house your code. It's right. Tomorrow I go to test in the my job with oscilloscope for the time test acquisition.

Thanks

I am using PIC18F2431 for the first time. Somebody possess an example of as to configure the A/D for this chip?

Somebody obtained 200ksps converter?
