I. General Introduction to USBasp:

1, the download line, is "ISP" (In System programmability: "is programmed") or "IAP" (in the application programing: "In the Application Programming"), is "the online programming" one way.

Here usbasp download line, refers to the use of ATMEGA8 chip, analog USB interface, and control the download process of a circuit unit, mainly suitable for the AVR series of chip program download (read and write), now make the user corrected firmware can be used for S51, S52 Series Chip program Download (I was used to download to at89s52).

Fischl_de USBasp is the "originator" of the usbasp download line, which has been continuously launched in various versions. The link to the webpage is: http://www.fischl.de/usbasp; If you are interested in depth, the Web page has the source program can refer to ...

2, usbasp because does not need the computer serial port or the same port, only uses the computer USB interface, therefore has the certain practical value; The domestic also has carried on many imitation and the improvement. For a more focused discussion, you can go to the OURAVR website to learn:

3, usbasp download line can be applicable to the MCU chip, and usbasp itself firmware (control program) and supporting the use of computer software related. For example, the usbasp firmware, which is described below, adds support for the 89S51/89S52 chip.
