 Forum: General CCS C Discussion Posted: Fri Jan 14, 2011 2:33 pm Subject: Int -> float incorrect cast |
| The y != float is the only error or warning and it isn't a function so I don't know what's causing the problem.
I am using math.h if that could cause any issues. I mention this because it's full of ... |

| Ok well I really appreciate your help. I'm trying to switch it over to a single compilation unit. This isn't the first time I've run into problems with extern. I've just always figured it out before. ... | |

Forum: General CCS C Discussion Posted: Fri Jan 14, 2011 1:32 pm Subject: Int -> float incorrect cast |
| So I tried something else.
I made two unsigned int32's max and num that are not external and assigned max_steps and curr_step to those respectively. Max and num ended up with incorrect values even ... |

| I can't get it to go negative now for some reason.
I also noticed I forgot to initialize the float so I did that and now I can get numbers below 1 but they're still significantly different from the ... |

| Alright so I have no idea what's happening here so hopefully someone can tell me what's going on.
I am using MPLab IDE 8.63 with CCS 4.114 on a PIC18F2620. I am using two int32 type variables to ... |

Forum: General CCS C Discussion Posted: Thu Jan 13, 2011 1:56 pm Subject: odd A/D conversion behavior |
| Well I am told the impedance is acceptable. Also I discovered something new that points to that not being the problem. I put in a delay of around 20 seconds and it still did it. The cap should have be ... | |

| Interesting. I had not considered saving to EEPROM only on power down. I will look into this as that would be much better.
I also misunderstood what extern meant then. I will change my code to refl ... |

| Ok I added PUT (and clarified my understanding and I get why it should be used now). The percent it tried to move to changed. This is the same thing that I always see when I change the delay. To me th ... | |

enable PUT as it allows the PIC to 'get going right'. trash the TRIS statements, let the compiler handle it... same holds true for the ADCON=....,again use the compiler commands... ... |

So long as you have #device ADC=10,, this will return the value you require. I have done this. The result seems to be getting returned correctly as the motor corrects itself. What appears to be h ... |

| Hi everybody, I'm not sure if this is a CCS problem or an MPLab problem but I'm trying first here as I've had much better responses here.
I am using the PIC18F2620 CCS version 4.114 MPLab 8.60 M ... |
