this informations is very good,
The VPW that I will used is the ISO14230 by GM. I think that if I not have the ELM Chip, don´t start the tests.
while this is only theoretical studies. I save al ... |

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)

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?
