It's been awhile, so I expect to get slammed if I don't get this right. The PWM uses the number "25" as the total amount of time for your period. This means that you only have 25 steps. Y ... |

What's connected to your outputs, anything? I've seen external devices hold up the processor from starting properly if they are powered and the power finds its way back to some processor pins. As su ... |

You don't necessarily have to convert it then compare it. You could do this:
// declare variables
int num_int;
float num_float;
// Get your data into the variables as you need to
num_int=127 ... |

Has anyone ported the J1939 code from Microchip to CCS and the dsPIC? Specifically I'm trying to get the J1939 code running on a dsPIC30F6012A. I'm also wondering what would be the best way to acces ... |

Typically and end of string mark is a zero (0x00). What character shows up after your number? Make sure it's a zero like
number[12]=0x00.
If that doesn't work then you can alsways do it the ug ... |

I think I get the pulse when I do this line:
setup_compare(6,COMPARE_PWM|COMPARE_TIMER3); // using OC6 = Pin_RD5
I don't know what else to try. |

I have PWM working on a dsPic30F6012A. Is there a way to not get the first startup pulse? At each bootup there is a short full-on pulse until the PWM gets into sink and starts back at 0 PWM.

OK, I have lots of IO pins working now, except for G7 and G8. I think it may have to do with the second function of these pins. Datasheets call out CN9 for pin G7 and CN10 for G8. How does one disa ... |

The above code didn't work. I had to change pin_g7 to pins_g7 because pin_g7 was already defined. Still didn't turn the port on. |
