Hello friends, hope you all are fine and having fun together with your lives. In today’s tutorial, we are going to see however one can compile and simulate PIC18F . Its my first tutorial on that and I am progressing to post quite an heap of  tutorials on PIC18F Microcontroller in coming week.

it is my first tutorial on PIC18F Microcontroller that’s why it's quite an easy one , I will 1st of all have a glance at only 1 single pin(I/O) during this Project,  a  basic circuit for PIC18F Microcontroller. After that, I will be able to attach a light emitting diode(LED) on any of its I/O pins so will switch to it  high state. I even have additionally given the Proteus Simulation along side Programming code designed in miKroc and CCS . So, let’s get started with it. 

Proteus simulation for First project

  1.  First ,we need a simple circuit to simulate for I/O Project for PIC18F4580 Microcontroller in Proteus ISIS, as you all understand Proteus is appropriate simulation tool for MC.
  2. Once the electrical connection  is done for simulation, I need  the programming code for Microcontroller.
  3. In order to develop the code, two compilers miKroc and CCS are used  .you can use anyone of them.
So let’s create a simple circuit for the Proteus Simulation and run it.

Circuit diagram to connect Led with PIC

Reference above image for circuit

  • Notice that  a 5V is connected with Reset pin of PIC18.
  • LED is connected to RA0(PIN designator) of Port A.
  •  Next, we will take advantage of useful C language by using compliers to  develop programming code for  Microcontroller that is running on top of image and produce an running LED.

mikroC Programming Code for (PORT A) first Bit. 

  • Now as I have mentioned earlier, the compilers I have used for designing the programming code for  Project are mikroC and CCS.
  • So I hope you have installed any one of them on your computer and if not then must install it as otherwise you won't be able to compile this code.
  • So now create a new project in your mikroC compiler.

CCS Programming Code for (PORT A) first Bit. 


Program to turn on led in PICC
  • Inside the while() loop, we have used the first bit of PortA  in which it's sate is made high and so led  is ON.
  • Now after adding the code in your anyone of your choice complier, compile it and get the hex file.
  • Proteus allows us to upload  hex file into your PIC Microcontroller model ,just double click on controller and browse your hex file, Press run button to start simulation. 
  • If everything’s goes fine ,code should run as expected.

How to use SPI Debugger

By
  SPI Debugger Hi Friends, in this post, we will discuss how to use SPI Debugger available in proteus for serial peripheral interface (SPI) which is a built-in feature of PIC microcontroller to communicate and data exchange between PIC and other devices. SPI Debugger Introduction to SPI Guys, SPI can be considered as a programmable shift  register, The SPI module is a synchronous serial I/O port that shifts a serial bit stream of variable length and data rate between the PIC and other peripheral devices. Here “synchronous” means that the data transmission is synchronized to a clock signal. To avoid further delay, let's see some important connections and different configurations to effectively use SPI Debugger. How to use SPI Debugger in MASTER & SLAVE configuration Select the virtual instrument and from the instrument, list selects "SPI Debugger". SPI Debugger Insert two SPI Debugger on the working area, select any one of ...

PIC18f4580 Timer0 calculation using miKroC , CSS and proteus

By
PIC18f4580 TIMER PROGRAMMING The PIC18f4580 has four timers. they're named as Timers zero, one, two, and three. they will be used either as timers to come up with a time delay or as counters to count events happening outside the microcontroller. First, we see however Timers zero is employed to come up with time delays. Every timer wants a clock pulse to tick. The clock supply will be internal or external. If we have a tendency to use the inner clock supply, then 1/ fourth of the frequency of the crystal oscillator on the OSC1 and OSC2 pins (Fosc/4) is fed into the timer. Therefore, it's used for time delay generation and for that reason is termed a timer. By selecting the external clock choice, we have a tendency to feed pulses through one among the PIC18's pins: this is often known as a counter. GIF  taken from  https://exploreembedded.com Basic registers of the timer Majority of t timers in 18F are 16 bits wide. Because the PIC 18 has an 8- bit ...

Frequency Counter using Interrupts PIC18f4580 Project

By
Frequency Counter  using PIC18f458 0 Proje ct This POST describes the construction of small frequency counter with a cheap PIC18f4580 microcontroller with 16 x 2 LCD.   Prerequisites: PIC18F4580 TIMER Programming. PIC18F4580 COUNTER Programming. PIC18F4580 Interfacing with 16x2 LCD. PIC18F4580 Interrupts Programming  ( we will cover in this POST) Concept: Frequency  is the number of occurrences of a repeating event per unit time. in our case we will measure a number of clocks generated by clock source per unit time. In this project, LCD is used to display the frequency and PIC timer 1 to measure the input signal and Timer0 to generate an indication that one second has gone. System software utilizes Timer-1 in the 16-bit counter mode to count the input signal and overflows of the counter are added to provide the aggregate count in multiples of 65536. Totaling the existing value of the counter at the conclusion provides...
