Thank you PCM! I was exactly thinking about something like that but didnt know how to do. In Delphi I was using Trunc(float) and Round(float) func ... |

| Get more accuracy with floating point math:
#define VoltToByte(x) x*(255/30.0) Now 77h = 119 NICE! Thank you very much!!! |

| Hello again.
Friends, I was trying to use this technique in my code, test code is like this: #define VoltToByte(x) x*(255/30) //Voltage will be divided by 6, so maximum will be 3 ... |

| I dont want to jump into int16.
Above 5v for sure not, but for exact 5v is possible. There is a way to compare ADC to 5v without using int16? Using 0.0196 instead of 0.01953 will add a small er ... |

| Wow!
VERY NICE! Ttelmah code looks more interesting for me, more flexible and voltage value keeps exposed in the code. So, I can securely make any math like this "#define int_adc(x) x/0.01 ... |

This may be a very basic question, my english is poor so I will try my best to explain what I need. I want to work with voltages using the ADC. Several times I just want to check for a vol ... |

I think I understood it, thank you. Ttelmah, I still have a doubt... Using this kind: #byte TMR1L = getenv("SFR:TMR1L") Can I port it to another uC which have a TMR1L ... |

Have a look at the thread example I posted, which shows how to do this with a #BYTE. However, remember that for things like the timers, you want to access them in a single I/O operation i ... |
