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
Questions: 1. is your 16f877a using a crystal oscillator? 2. are you confident enough to use interrupts? The crystal will be necessary if you want accurate timing. There are several ways to produce delays and each has good and bad points. The most 'universal' method is to use timers and interrupts but the code is more complicated. You can do it
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, With a 16f877a PIC configure the PIC as the master and just read the I2C 24C04 EEPROM data into the PIC. Do you have a datasheet for the IR thermometer which shows the I2C protocols required.? Which language do you use for programming.? If its assembler I may be able to help. E

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
