Intel Hex Files Explained

We often come across a problem where an understanding of Intel Hex file format will help in solving a programming issue or technical point. Intel Hex format is a standard layout for files produced by assemblers or C compilers when they compile your source code. It is used by device programmers to program the target microcontroller with your code.

Which Pic Programmer Do You Need?

Microchip PIC microcontrollers come in a wide variety of types from very old PIC16C family through to the latest PIC16F and PIC18F devices, with several other less common types as well. Apart from some very old chips, they are all In Circuit Serial Programmable, which means that they can be programmed in circuit using a PIC ICSP programmer.

How to Create a Long Range Bluetooth Wireless Link

We are all familiar with short range Bluetooth wireless communication as it is commonly used by our smart phones to transfer data or to connect to headphones etc. Computers also use it for communicating with the mouse, speakers or headsets. These are all short range applications but can Bluetooth wireless be used for longer range transfers?

PIC16F877A

The PIC16F877A (and earlier PIC16F877) are microntrollers supplied by Microchip. It is just one device among many PIC microcontrollers and it is a veteran chip compared with many others. There are lots of articles, projects and circuit diagrams available on the web that use the PIC16F877A so it seems to make sense to use it but should you still use this chip?

How to Program Arduino with AVR ISP Programmer

If you have been using Arduino to develop your code but want to move on to develop your own AVR based circuit or want to program your Arduino board with an external programmer to give more code space, you will need to understand how to use an AVR ISP or In System Programmer. This post covers the information you need

Where to find Arduino Hex files or Output Binaries

You can use a normal AVR ISP programmer to upload Arduino sketches to an Arduino board or to an AVR microcontroller in your own circuit, such as ATmega328P, ATmega8 or ATmega2561, but first you need to know how to find the hex files that the programmer needs. The Arduino IDE makes this as hard as possible for some reason. This post shows you how to find them and also how to make Arduino put them in an easier place to find in future.
