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.

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.

Top Uses Of Multi USB Travel Adapter

In today’s world getting stuck in a confined place without an Internet connection is worse than dying. Internet today has become more of a necessity than a privilege. In order to stay connected, one needs an multi USB travel adapters that offer a number of benefits to the users.

A multi USB travel adapter can be used to connect various devices like the computer, printer or a smartphone to a wireless connector and then to the internet, without the need of hardwiring to any network device like a router. The adapter can receive signal from the router and translates it on the computer allowing the user to use the internet when they are within the wireless network range.

These adapters reduce the need of using adapter cards that can be damaging to the computer. A travel adapter needs to be just plugged into a USB port on the device being used and eliminate the need of installing internal hardware into the device itself. When using these adapters, there is no need of cables all over the area be it in the office or at home.

Multi USB travel adapters are quite cheap and can be easily found at online stores. If your computer did not come with a wireless network adapter installed in it, you can easily purchase multi USB travel adapter instead of changing the computer to a new one that can work with wireless internet.

Apart from the travel USB adapter, another useful product is the CAN USB that makes life much easier for people who are always looking to stay connected without any hassles. You need to ensure that you pick the right quality product that will last long.

A Guide To EEPROM Chip Programming

The full form for EEPROM is Electrically Erasable Programmable Read Only Memory. These allow for the erasing of individual bytes or the entire memory space electrically without the need of UV light. The individual bytes can be easily erased without having to erase everything on the chip. Even though the process of burning is longer than the EPROM, they are worth the wait.

EEPROM is also called non-volatile memory, as when it is turned off, the stored data in the chip will not be erased. All the new EEPROM will not have any data in it and will have to be programmed by an EEPROM chip programmer before it can be used. All the information stored in this type of memory can be retained for many years even without a steady power supply offering many benefits to the users.

There are a number of functions of eeprom and they are used to store user programmable information like VCR programming information, CD programming information, digital satellite receiver control data, user information on various consumer products and much more.

It is also quite easy to understand if the eeprom data is corrupted or damaged. Some of the common symptoms are no high voltage, no display, horizontal or vertical frequencies run, cannot store any current settings, control functions like sound, brightness or contrast control do not function, on screen display does not function and many more.

EEPROM do not fail, they only have their memory corrupted seldom due to high voltage or static discharge. But, once these are reprogrammed, they will start to work as new. You can find a number of companies selling EEPROM programmer and you need to make sure that you pick the right one.
