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 20ºC), therefore this sum is always lower than 255.

I att ...

Hi everybody, recently I've found a trouble with my system. I'm using PIC 16F877A and 2 LM35DZ. Problem is when I run Proteus to simulate, when it's an even value, LCD shows exactly half this and when ...

Hi everybody, i'm having right now a problem with my project (simulating on Proteus). My project is a water temperature control systems through heater power control and valves opening.
Problem is whe ...

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

Following Microchip app directions, i've placed a 500M resistor to limit current.

Hello everybody, i'm new here and i need help, please. I'm trying to do a temperature control system for a water heater through power control with triac.
My problem is i need generate a control signa ...
