PIC18F2550 Microcontroller

‘PIC’ is the popular microcontroller series from MICROCHIP and PIC18F2550 is one of the popular microcontroller from ‘PIC18F’ family. PIC18F2550 is a High-Performance, Enhanced flash, USB Microcontroller with NANO-Watt-Technology. This is an 8-bit microcontroller popular among makers and engineers due its features and low cost. PIC18F2550 comes in various packages like DIP, QPF and QPN and can be selected according to the project requirement.

In this tutorial , i will show how to create melody using microcontroller and in this tutorial i will use pic18f2550 microcontroller .So let's create a project in proteus .

Proteus Project :

Please follow the instructions given below :

  Now pick pic18f2550, sounder, crystal,22pf capacitor,VDD and ground according to the instructions given below :

Now complete the circuit as given below :

MikroC Code :

Now  we need the source code .So create a project in MikroC and follow the instructions given below:

Source Code :

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

(adsbygoogle = window.adsbygoogle || []).push({});

void Tone1() {   Sound_Play(659, 250);   // Frequency = 659Hz, duration = 250ms } void Tone2() {   Sound_Play(698, 250);   // Frequency = 698Hz, duration = 250ms } void Tone3() {   Sound_Play(784, 250);   // Frequency = 784Hz, duration = 250ms } void Melody() {           // Plays the melody "Yellow house"   Tone1(); Tone2(); Tone3(); Tone3();   Tone1(); Tone2(); Tone3(); Tone3();   Tone1(); Tone2(); Tone3();   Tone1(); Tone2(); Tone3(); Tone3();   Tone1(); Tone2(); Tone3();   Tone3(); Tone3(); Tone2(); Tone2(); Tone1(); } void ToneA() {   Sound_Play( 880, 50); } void ToneC() {   Sound_Play(1046, 50); } void ToneE() {   Sound_Play(1318, 50); } void main() {     ADCON1=0x0F;   //disable adc     CMCON=7;         //disable comparator   Sound_Init(&PORTC,0);   Sound_Play(880, 1000);             // Play sound at 880Hz for 1 second   while (1) {   ToneA();   delay_ms(100);   ToneC();    delay_ms(100);   ToneE();    delay_ms(100);   Melody();   } }

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Now follow the next instructions .

.

Now just run the project.

Thank You!

Tutorial for Blinking a Simple LED using PIC18F2550 microcontroller using XC8 Compiler. This simple tutorial includes two different source codes showing basic ways to program a PIC18F2550 . The source code can be easily modified for C18 Compiler. The project files and source codes are free to download.

This is a simple project to demonstrate the USB custom hardware interfacing with Unity3D game engine on top of Microsoft Windows operating system(s).
