PIC18F PINOUT

Vdd(Vcc) Two pins are used to provide supply voltage to the chip.The typical voltage source is +5V DC. Vss(GND) Two pins are also used to for ground. OSC1 & OSC2 The PIC18F has many options for the Clock source.Most often a quartz crystal controller is connected to input OSC1 & OSC2.The quartz crystal oscillator connected to the OSC1 & OSC2 pins also needs two capacitors.One side of each capacitor is connected to the the ground as shown in figure below: PIC18F microcontroller can have speeds of up to 40 MHz. Easy Programming  PICKIT3.5 PIC KIT3.5 PICKIT MCLR Pin1 (in the PIC18F4548 40-pin DIP) is the MCLR (master clear reset) pin. It is an input and is active-Low (normally High),When a low pulse is applied to this pin,the microcontroller will reset and terminate all activities.This is often referred to as a power-on reset (POR). Port A, B, C, D & E The Ports PORTA, PORTB, PORTC, PORTD, and PORTE use a total of 3

Criteria for Choosing Microcontroller

Criteria for Choosing Microcontroller Choose Microcontroller Hi, Selecting an microcontroller is one of the daunting task even for an experienced developer. The one of the critical decision of your embedded application is to select the right microcontroller which control the failure and success of your project.  There are thousands of type of microcontroller each of them has unique feature or advantage from form factor or package size ,capacity of random access memory & read only memory that made them fit for certain application and unfit for  certain application. Microchips portfolio for microcontroller is broadest in industry. it includes ARM,PIC & AVR microcontrollers. Primarily experience with one these architecture is valuable and staying with that architecture reduced the development time. They also offer easy to use development environment and development board which reduced research time and cost. Consideration are important to pick the right part.

Difference Between Microcontroller and Microprocessor

Difference Between Microcontroller and Microprocessor  Tabular explanation Microcontroller vs. Microprocessor    Hello friends, in this post we will study the difference between microprocessors and microcontrollers. The first difference between MC & MP is that MP contains its Arithmetic logic unit, control unit, Random access memory, Read-only memory, and input & output ports, they are all on different circuits, which means we have to whenever MP wants to have some access to its memory and input-output ports and the serial communication port, we have to use the interfacing because all these components are not present on the single chip.   In the case of MC, the memory, input & output ports, timers, counters, arithmetic, and logic unit, and control unit all are present on the single chip. There is no need for interfacing, all devices are embedded on the single-chip so they can communicate easily. The second difference we have is, in MP memory and

Pic Introduction

PIC controller different form factor Are you spotting for basic material concerning the PIC microcontroller? This post can assist you to acquire precise basic information about the PIC microcontroller.   Introduction to PIC PIC microcontrollers ( Programmable Interface Controllers), Digital Electronic circuits that may be programmed to accomplish enormous tasks. They will be programmed to be timers or to regulate an assembly line and far additional. They're found in most electronic devices like alarm systems, laptop management systems, phones, actually nearly any device. Many varieties of PIC microcontrollers exist, though the most effective is in all probability found within the jinnee vary of programmable microcontrollers. These are programmed and simulated by Circuit Wizard code. PIC Microcontrollers are comparatively low cost and might be bought as pre-built circuits or as kits that may be assembled by the user. A brief history of the PIC microcontr
