 Forum: CCS ICD / Mach X / Load-n-Go Posted: Tue Jul 31, 2007 7:05 am Subject: Could not detect target chip |
| The reason CCS does not have a "fix" for this is because it is most likely a hardware problem. Hook up an oscilloscope to your ICSP data and clock lines and also your Master clear and ensure ... | |

| I never did find a solution. i had to buy another ICD programmer.. sorry.. Someday if I have time I will probably troubleshoot the old programmer some more. If you ever find out feel free to tell me. ... | |

Forum: General CCS C Discussion Posted: Fri Feb 16, 2007 11:25 am Subject: PIC with 4 external interrupts |
| Thanks also newguy, the only problem with that is the extra overhead involved, and the system i am using this on is a critical system that needs immediate response, so determining which pin went may a ... | |

Forum: General CCS C Discussion Posted: Fri Feb 16, 2007 11:22 am Subject: PIC with 4 external interrupts |
| Perfect! I did not feel like multiplexing the interrupts or using the portB interrupt on change as these are critical time constraining interrupts and real estate and extra hardware are an issue.

| Hello,
Just a quick question. i am curious if there is any PIC's with at least 4 external interrupts.. I saw an old datasheet of the PIC 18F4431 with 4 ineterrupts..but when i go on the microchip s ... |

Forum: General CCS C Discussion Posted: Sun Jan 21, 2007 10:52 pm Subject: Problem solved |
| I enabled the interrupts in the function that the main program called and it worked fine.. My program has a while(1) loop that waits for a variable to be set from the ISR, which always worked, it was ... | |

| Yah, I read that thread earlier and tried that with no luck. It still waited until my delay_ms() was comlplete.. I exaggerated the time and made it 10 seconds, and it did not go to the interrupt until ... | |

Forum: General CCS C Discussion Posted: Sun Jan 21, 2007 3:38 pm Subject: Enabling interrupts during a delay_ms() or while() loop |
| Fair enough. That should work for this case.. but for the sake of being more flexible, do you know of anyway to use the delay_ms() command and still have interrupts active? Also, what is a list of com ... | |

| Hi all,
Compiler: 3.239 PIC: 18F4320 I am implementing code in which I have external interrupts on int0 and int1. These interrupts are a on/off button and a reset button on my project. The prob ... |

Forum: General CCS C Discussion Posted: Sun Jan 21, 2007 1:25 pm Subject: Thanks! |
| I believe the problem was with portB not configured as input on startup causing a multitude of interrupts on startup. And I believe the interrupts have a stack? Either way it seems to work great now! ... | |
