I have difficulties to hear a clear question, I can just guess that the problem is how to connect two modules with UART interfaces to a PIC16f877a that has only one UART port? A simple way would be to switch to a more recent PIC type with two UARTs. Presuming you are tied to PIC16f877a, implementing a software UART would be another option. It ha
Hello all my dear friend! I know can only make portA for input, but how to make PORTC for input?
hello sir i am doing my project on embedded pic controller 16f877a and i have got the meter for reading the solar panel data such as volts ,amps, freq etc .and this data is taken from MODSCAN software ,but i want to use or import the data from MODSCAN to MATLAB please do tell me the procedure to import the data and display in matlab.
my project is to make a remote control's protocol decoder supposing that i have a remote control and dont know what its protocol so i wanna use my pic decoder to know it using pic 16f877a and MIKROC u know the recieved IR signal is a punch of pulses some are zeros and the others are ones if i know the width of every pulse and the time betwe
Hi, Are you using Mplab V8.92 or the newer MplabX ? Have you Created a new project ? Have you loaded the 'Template' file for the 16f877a from Mplabs Template folder? This will get your project set up ready for your detailed code. picture below However you need to make one change to that template code, the Config LVP should = (...)
Hi, i am new to PIC microcontroller programming. i just installed the MPLAB, when i testing with the code online which i think is error free, it failed to build. it comes out the message below: Build C:\Users\Fei\Desktop\Final Year project\PIC code\test\test1 for device 16f877a Using driver C:\Program Files (x86)\HI-TECH Software\PICC\
i am doing a timer project in pic16f877a to control 3phase motor. to prevent emi i am using rc snubber in the motor side then using line filters in the microcontroller supply side then i am also using 5v TVS diode, more than this to prevent external emi i am covering the whole pic board with aluminium box and connecting the aluminium box to the neg
hi.. i m making a project in which i need to extract the longitude and latitude from GPS frame.

In my project i am using 16f877a & created 2 pwm in timer2 using pwm mode and also used timer 0 for external interrupt count and timer 1 to decrement a variable for every 1 second if i use pwm and timer0 there is no problem in pwm.but if i use all three timer pm getting affected
Something like this maybe? // simple 38 kHz PWM generation for PIC16f877a // check PWM library selection in IDE // PWM output is on RC2 // ensure oscillator settings are correct in mikroE configuration settings void main() { PWM1_Init(38000); // turn on PWM at 38kHz PWM1_Set_Duty(128); // 50% duty cy
Hello experts In my project , I want control & display the speed of the Wiper Dc motor(12v,5v). For this I am using the PIC 16f877a and IRFP150n (MOSFET). Now I control speed of the motor with help of PWM. I am using the proximity sensor to sense the speed.for my problem , how can get the speed with help of the proximity output si
Your code is CCS Compiler!!! And incomplete!!! Change #include instead #include <16f877a.h>... In MPLB change the toolsuite (menu project - Set Language Toolsuite... and choose the CCS C Compiller......etc)... Or create the project in PIC C Compiler...
do i need an Xbee or a ZigBee to send a msg from the GSM to the PIC 16f877a thank you
hi i have a GSM module and PIC16f877a , any project suggestions please thank you
Please, am new to the project world. I am also a newbie at this forum. Pls i need help concerning this project. I am meant to 'get speed' and 'set speed' using a GSM modem, PIC 16f877a, LCD, DC motor, Optical encoder. I don't know how to program the microcontroller to set the speed using PWM and get the speed from the Optical encoder.
pic 16f877a is a best controller for this project. This contains inbuilt ADC , SPI protocol. so it is very effective for your project.

Hello, I'm an engineering student and im making this project just for education purpose, I'm using: -PIC 16f877a with 10 Mhz quartz -DS1307 with 32.75 kHz crystal The problem is that after some time (random, sometimes 10 minutes, sometimes 10 days) the DS1307 just stops incrementing the time. BUT after I "reprogram" the DS1307 (set the time
ok First of all you need to have some circuit diagram for it....another thing why do you want to use two processor PIC16f877a and PIC16F72 ..... My suggestion here will be do this project in LCD than doing in seven segment displays as multiplexing seven segment require one interrupt timer...... Good Luck

Hi. I have an issue about a program for my project. I am taking two inputs from RD0 and RD1. When RD0 is 1, the output at PORTB should be 1. When RD0 goes to 0, controller should check for RD1. When RD1 is 0 while RD0 is also 0, the output at PORTB should be 0. When RD1 goes to 1 while RD0 is 0, the output at PORTB should be 1. The program executes
