How Does PIC Programmer Works?

A pic programmer is a circuit that interfaces the PC to the controller using the PC’s parallel, serial or USB port. It is used to write data to the microcontroller and also read it back for verification. It translates the digital logic levels from the PC to the more logical level for the microcontroller.

Most of the pic programmer except for the bootloader works mostly in the same manner. It generates the serial data stream using two signal lines clock and data. There is another pin that controls the programming voltage while two others will supply power and ground. There is another program that runs on the PC and takes the hex file generated from the compiler and translates it into the serial data stream. This will be routed to the programmer through the correct interface. From here, the programmer sends the signal to the microcontroller. Once all the data is sent, a serial configuration word is sent and the microcontroller becomes ready for use.

You will find several PIC programmer circuits in the market and all of them will more or less the same thing. These are supplied empty and are without any program codes. It is the task of the programmer to provide it with a program that will tell it what to do. You need to make sure that you buy quality product from a reliable supplier so that they can be used as they are intended to without facing any issue. Even then, many people are not happy with the programmers that are available in the market and choose to build their own pic programmer circuit for better control.

A Short Guide To EEPROM

An EEPROM or electrically erasable programmable real only memory is like a regular ROM chip that uses a grid and electrical impulse to create binary data. The main different between ROM and EEPROM is that EEPROM can be reprogrammed without having to remove them from the computer. One only needs a localized charge from an electrical field to erase the EEPROM chip. In addition, one do not have to erase the entire chip all at once and can make only specific changes when needed.

There are many different types of EEPROM chips available in the market that are categorized by several features including memory density, memory of organization, nominal supply voltage, maximum clock frequency, write cycle time, maximum access tie and packaging type. You can find the one that best meets your specific oarameters.

EEPROM are used in computers and many other electronic devices to store small amounts of data that must be saved the power to the device are switched off. EEPROM memory is used in many different devices like digital potentiometers, digital clocks and digital thermometers.

With so many different types of EEPROM programmer kit available in the market, it is important to choose the right EEPROM chip depending on your needs. The first thing one needs to assess their needs and then find a suitable one. One also needs to keep their budget in mind when looking for the right chip as the more advanced one will be expensive compared to the basic ones that are easily available in the market.

A Guide to Microcontroller Programmer and AVR Development Kit

If you are interest in studying and learning microcontrollers, there are a few things that you need to know. A number of people want to convert age old digital based design into something that is based on microcontroller, but do not know where they need to start. Here is a short guide to help those people understand what microcontroller programmers are.

Before you can start with the programming system, here are some of the steps and tips that you need to know –

• You need to have the right ability and knowledge about programming. But, just having a master degree in C programming will not help. It is important to have the ability to analyze a problem statement and solve it too. This is the most important skill that you will need if you want to work on any microcontroller system.

• You need to have the required software and hardware to make a microcontroller based embedded system. The microcontroller is a form of hardware of the system. It has a tiny chip known as the microcontroller that stores a preset program inside of it known as software.

In order to get started, there are four important things that you will need namely a temperature sensor, a microcontroller, 5V DVC voltage regulator and a 16 chars by 2 lines. When looking for AVR development kits in the market, you will be able to find a number of them, but only you can decide which one you need depending on what you want to do with it.
