The problem has solved for now.
I was using a 100uF capacitor at the output of 7805, but I changed it to 470uF. After that, the circuit is working properly and the controller is not getting reset.
Thank you for your time and replies everyone!!!

Yes the circuit works well. I have not experienced any issues with mobile phones or wifi.
But I would surely consider having a ground plane in PCBs now onwards.
No there is no ground plane on the PCB. Is it necessary to have a ground plane in the PCB?
I have used the same chip in another circuit where the PCB does not have a ground plane. The only difference being that there is no connection between the mainline neutral and the 5V ground and it is...
Hi there,
I am facing an issue of MCLR reset in my PIC16F887.I have connected the connected the recommended components as per the datasheet, at the MCLR pin. I am using this chip in a product where we are sensing the mains input voltage. We have used a 12V SMPS to give supply to 7805 to generate...
Re: How do I convert BCD value into integer value
Thank you very much for your response.I understood now what you are trying to say about displaying the BCD value.
Re: How do I convert BCD value into integer value
There could be a misunderstanding.I am a beginner in embedded c coding,so forgive me if my questions are silly.But according to the datasheet the values of calender and clock are stored in BCD format.I am using a standard code for displaying...
How do I convert BCD value into integer value
I am making a clock by interfacing RTC ds1307 with PIC16F877A.For the display I am using 4 seven segment LED displays.The data read from RTC is in BCD form.In order to display the value on the 7 segment display,I need it to be an integer value.Can...
I am using MPLAB X IDE v3.61.
I closed the project output window by mistake,after building a project.
Now,I am not able to open the output window.I tried to open it by going to Windows>Output.
I also tried to open it by its shortcut key Ctrl+4.
However,none of that is working.Is there anything...
Yes i do have the schematic in proteus,but all it has is a chip and an led.
Yes the configuration bits in IDE match withe pragma directives.
I sm using a development board to program the chip,which is powered by a 12V smps & Vdd=5 Volts.I have pulled up(5 Volts) the pgm/rb3 pin,for LVP(Low...
YES the code is running on proteus.
This is the code i have used:
#include <xc.h>
#define _XTAL_FREQ 20000000
// CONFIG
#pragma config FOSC = HS // Oscillator Selection bits (HS oscillator)
#pragma config WDTE = OFF // Watchdog Timer Enable bit (WDT disabled)
#pragma config PWRTE...
I am using pickit3 programmer to program my pic16f877a.
The problem i am facing is that,even after i am done with loading the whole program on to my chip,the CODE IS NOT RUNNING ON THE HARDWARE.
I have loaded a simple led on/off program.
I am using LVP method for programming.I have pulled the...
Well..what i want is not exactly an alarm setting..
I want to make the clock with multiple ON OFF time settings..
So i want that I can enter multiple on & off times and the real time keeps running simultaneously..
Is that possible??
