USBDownloader

Downloader or programmer in the world of microcontrollers is known as a tool that can be used to fill the program into the microcontroller chip. Downloader or programmer is a tool or tools that you must have when you want to fill the program into the microcontroller. Microcontroller downloader of many kinds, depending on what brand of microcontroller you use. Each microcontroller factory usually sells its programmers separately. You can buy it according to what microcontroller chip you use. Downloader or microcontroller programmer can also be made by yourself. Lots of series of microcontroller downloader or microcontroller programmer that you can see on the internet. One of them is an AVR microcontroller downloader named USBasp. USBasp is one of the open source AVR microcontroller. You can download the series for free. You can also create your own downloader series without having to pay a license to the circuit builder. As a reference I am referring to the source website USBasp located at the following link http://www.fischl.de/usbasp On the link is displayed a lot of downloaded pcb downloader series. If you are lazy to create your own pcb circuit, you can download from the link. To make a series of USBasp downloader, I am using free PCB design software that is Cadsoft Eagle PCB. The software can be downloaded at the following link http://www.cadsoftusa.com/. I Connect the finished Downloader to the newly created downloader, because it will do the cloning / inject driver USBasp. Then provide another USBASP (Downloader) to download the firmware to atmega8. (Downloader does not have to be USBASP based which can be other compatible origin with MOSI, MISO, SCK and AVR microcontroller reset). This way requires two USBASP downloaders. One as 'USBASP' which I use as the target board and the other as USBASP downloader. To make USBASP a target board the way is by connecting the jumper self prog. I love Redcolor PCB. Its cool, only $5 10 pcs, best way to create pcb on PCBway
