5. CUSTOM PROJECTS
Though there are many microcontroller programmers on the market, you can build one for just a fraction of the cost. There are two options: either you buy a preprogrammed microcontroller, or you build one yourself. Please, see Microcontroller programmers section, if you would like to build a programmer for a few euros or dollars…
Now, when you have a programmed microcontroller that talks to your computer as a HID USB device, you just need interface software to control it from your PC. The easiest way is to use a suitable DLL that comes with the HEX file. DLL implements simple HID functions and provides for inter-thread and inter-process synchronization. The latter means that you will be able to access the microcontroller from different threads of one application, or from different threads within other applications (see Multithreading support for more details). Now, you just have to write your own application… See section “How to start programming PIC18F24J50 or PIC18F26J50?” for details.

Programming microcontrollers from scratch is relatively difficult due to many open questions that may arise. The first task is to build a programmer circuit. Next you need to write a programming application that programs HEX files. But this is only a half of the story. You also need a microcontroller programming environment, at least an assembler and a linker. However, it is more convenient to install a more complex development environment with a higher programming language like C, C++ or Basic. if you have to solve a more complex problem, you should also consider using Microchip program libraries. The next task is to get as much documentation about the microcontroller you are about to program as possible. It is important to understand the microcontroller's architecture and its functional units operation before you begin programming.
