In reply to: PIC16F877A with DC Gear Motor
Firstly, above code is for MikroC Pro compiler. You can reduce the voltage of Proximity Sensor using Voltage dividing resistors and/or zener diode.
Continuous pressing of switch is not required, it depends on how you program (how many times you read switch) etc.

Not enough RAM for call stack __Lib_Delays.c
how to solve this problem.
In reply to: Microsecond variable Delay in MikroC
It is very difficult to obtain accurate variable microsecond delay function. Make the oscillator clock frequency as high as possible and you can use Delay_Cyc() in MikroC which creates delay based in clock cycle. You may also try creating your own delay function like the following (following code is not calibrated for microsecond).
void Delay(unsigned int i) { for(;i>0;i--) { } }In reply to: Microsecond variable Delay in MikroC
Micro second variable delays will be very difficult to create and it will not accurate too as each instructions will take a few microsecond to execute. That is why MikroC doesn’t implement this function.

I would like to know why are they adding 48.
// Convert temp_fraction to characters text[4] = temp_fraction/1000 + 48; // Extract thousands digit text[5] = (temp_fraction/100)%10 + 48; // Extract hundreds digit text[6] = (temp_fraction/10)%10 + 48; // Extract tens digit text[7] = temp_fraction%10 + 48; // Extract ones digit
Thanks for your help 🙂

If you are using MikroC, please use the HELP section to find details of SoftUART library. It is very easy to use.
Topic: PWM by pic 16F877A
Hey guys,
I am using 16F877A to output PWM, increasing and decreasing it via two push buttons its based on the code used in DC Motor Speed Control using PWM with PIC Microcontroller in MikroC but the problem is that after a certain PWM value the PWM will not decrease and I have also added a switch with instantly makes duty value zero but it also doesn’t work after a certain pwm value and I have tried it on Proteus as well as with leds in real life but they give the same result. Only way it goes low is to keep pressing the UP button then some how it come down to a low value then other two switches start working and I then can switch it pwm off. Don’t know whats wrong.
Here is the code:-
{ adc = ADC_Read(1); // Get 10-bit results of AD conversion rpm_temp = adc * 2; //converting analog value to rpm WordToStr(rpm_temp, speed_out); //converting integer to string to disply on LCD Lcd_Out(2,9,speed_out);//Write speed in 2st row 6th col Delay_ms(100); if (RD0_bit ==0 && duty<250) //if button on RD0 pressed { Delay_ms(100); duty = duty + 10; //increment current_duty PWM1_Set_Duty(duty); //Change the duty cycle } if (RD1_bit ==0 && duty >0) //button on RD1 pressed { Delay_ms(100); duty = duty - 10; //decrement duty PWM1_Set_Duty(duty); } if (RD2_bit ==0 && duty >0) //button on RD2 pressed { Delay_ms(100); duty = 0; //reset duty PWM1_Set_Duty(duty); }In reply to: PIC16F877A with GPS and GSM for tracking purpose
Yes, you can. You have two options.
- Multiplex UART using IC 74HC4052
- Using Software UART, which means that you can program any GPIO pin of PIC as UART. MikroC Pro provides built in library for that.

MikroC functions are 100% working..
You can use the following MPLAB XC8 tutorial to write your own functions.
Topic: USART PIC16F877A
I have used the c code for the USART module from the tutorial. I can not get it to work. I am using MikroC Pro with the EasyPIC 7. I know the compiler has its own function for initializing the module but I would like to write my own. Please help.
I want to display data read from UART on 16×2 LCD with MikroC compiler & PIC16F877A microcontroller …
In my program I am sending data through USART terminal of MikroC, it is receiving correctly on virtual terminal in Proteus but not displaying on LCD.
