First tutorial on Pic Microcontroller programming ( MikroC + Isis ) HD


Hi guys! Mouad’s here and welcome to this new tutorial on how to program the PIC microcontrollers. We’ll use for this tutorial the MikroC for PIC and the Software Proteus Isis professional to simulate our project today we will use the PIC16F84A to blink a LED which is connected to to a pin of this microcontroller, in our tutorial it will be the RB1 which is connected to our LED via a resistor so let’s start by making our program go to project, new project, next give a name to your project choose the directory choose the PIC16F84A choose the Clock device clock 4 Mhz next,next and finish in MikroC environment will give you
directly the void main function which is the function of the main program and you will find it in every. it must
be in every program you develop in mikroC there are two instructions you have to know by heart. the first one is the TRIS and the second one is PORT in the first one you will add for example TRISB which means to configure the portB as an input or an output and if we want to use portA you will make TRISA in our project we have the LED connected to the B port we will make TRISB=so in MikroC if you want to configure to your pins as an output you have to set TRISB register to zero if not, you want to make it as an input you have to give it the value 1 so let’s give it value zero give it type “b” for binary and I will type 00000000 why 8 numbers so if you see here you will find that the B-port have 8-pins RB0 to RB7 which means it has 8 bits 8 pins our LED is connected to RB1 here, and we want to make it as an output we’ve made a mistake here it should be the opposite so, the Zero means as I’ve told you that 0 means that our pin will be an output and the other will be as an input here is the RB0 RB1,… RB7 the second one is the PORTB instruction, in our tutorial we will use the PORTB, if you give the PORTB for example will give it in our simulation you can see that the LED is connected to portB1 so if I want you change the status of the LED I should use PORTB.F1 why F1? F1 means that I will affect the value of the first pin here, and not pin0 or other pins and I give it for example the value 1 this means that our LED will be ON if I make PORTB.F1=0 that mean that our LED will be OFF so in order to make will LED blinking I will need to to add a while(1) which means that our program will be executed infinitely so you can see that our LED will at first be ON the OFF but our program is executed fastly so I will not see the changes of the LED status I will have to add a delay I will use the instruction delay milliseconds for example 500ms so our LED will be ON then Delay and OFF and I should add a delay here 500ms as I told you, our program will be executed in infitive time our LED will be ON, Delay, OFF, Delay here is our program you have finished your first program last step is to build our project, to compile it so in order to do that click here and you can see that your project is built successfully and you can find a different information about the used RAM and ROM free RAM and free ROM so now let’s simulate our project by going to ISIS professional , double thick on your microcontroller let’s set our clock to 4Mhz LEDBlinking you have to choose the HEX file okay click on Play here is the LED blinking and it will do that in an infinitely so I hope it was useful for you if you like it subscribe to our
channel: there will be more videos in the future good luck and bye!
