Ok, I changed pins configuration as you show in lcd.c and it worked so good.
Thank you very much PCM programmer. |

Hi, thanks for help. I've made changes you proposed, but I can't get LCD shows something yet; when running simulation on proteus, LCD pins don't show a color (red or blue) indicating 0 or 1, it's like ... |

Hi everyone, I'm working in a power and energy meter what uses a LCD to display these variables and power factor.
I'm having a problem, because I think display routine is right, but in Proteus and i ... |

Thanks for your replies. I changed ADC clock value to 8 and I did a modification (I wrote the formula temp = 0.5*(read_adc()-1) and simulation shows correct values, but right now I've found another tr ... |

Here is full code. I don't know how shrink it. Regarding ADC channels, I'm using two sensor, then I need two channels (or not?).
#include <16F877A.h>
#device ADC=10
#fuses XT,NOWDT,NOPROT ... |

Ok, I made changes you told me, but LCD still shows the same values. Regarding temperatures addition, their values are small (no more than 20ÂșC), therefore this sum is always lower than 255.
I att ... |

I'm sorry, I mistook, i used a 500k resistor. Regarding opto-couple, i didn't think it before, but unfortunately it's not long until i have show project to professor.
Thanks |
