I put the following code out side of main loop. Still I have same problem.
Eeprom_Write(0x00,new_temp_mem);
Delay_ms(100);
//Fan1 RPM
Eeprom_Write(0x02,new_rpm0_mem); //lower byte
Delay_ms(200)...
Already done. My problem was after adding Eeprom_Write to the program, it's look like the program hanged. There is no response from buttons and nothing in LCD screen.
For testing, I just put the function outside of the main loop. Still same problem. There is no response from any buttons and...
Sorry, I can't post all the details here. As I posted in the first post, I am experiencing problem with Eeprom_Write function. When I add the function, the LCD will blank, even before executing it. Otherwise, the entire program is working fine.
Thanks for the reply. new_rpm0_mem is a 16bit int value. As you can see, I want to write the values to EEPROM on button press. But the LCD is blank even before the program entering into the menu loop. That's causing headache for me.
I am using counter in PIC for counting the RPM. The counter...
I am writing a firmware for my project using PIC16F877A and Mikroc. In this firmware, I want to change values stored in EEPROME of PIC. The circuit have 6 buttons for selecting and changing values. The buttons are connected to various pins of PORT D. All of the functions are worked without any...
I tried with low value resistor. Because of very low current, the voltage across resistor is not suitable for measurement purpose. So I am considering CT. Can you help me to design a CT for the same ?
I want to calculate the current taken by an Axial fan - rated 230V AC - continuously and alarm if the fan fails or it overloaded. I am considering a CT based solution. But I can't find any design that suitable for my purpose.
Thanks for help from everyone. The actual problem was related to the Display_RPM function. The corrected code is posted here. Special thanks for bluelasers for correcting the shift left function.
void Display_RPM(unsigned int num){
value[0] = (num/10)%10 + 48;
value[1] = num%10 + 48...
I am also using interrupt. The code, I posted earlier was the Interrupt handler in MikroC.
I have some other doubt.
state = 0;
state = state + PORTB.RB0;
state = state << 1;
state = state + PORTB.RB1;
level = level + bump[state];
Display_RPM(state);
This is the code, you posted earlier...
Actually, it's a Arduino Rotor encoder library file, I want port it into MikroC for PIC.
const byte pinA = 2;
//encoder pin A to Arduino pin 2 which is also interrupt pin 0 which we will use
const byte pinB = 3;
//encoder pin B to Arduino pin 3 which is also interrupt pin 1 but we won't use...
int bump[] = {0,0,-1,1};
state = 0;
state = state + PORTB.RB0;
state >> 1;
state = state + PORTB.RB1;
level = level + bump[state];
Display_RPM(state);
The above code not working. I want to work the code something like this. I am using MikroC
consider...
I have no oscilloscope to confirm fan have tacho signal.
You are correct. It's caused the crap Chinese adapter. I tried with battery, 3000 RPM in display gone. But still there is no RPM Count in LCD.
1:2 prescaler is already corrected in program. Please see 41st line of the code.
