[avrdude-dev] New chinese programmer's driver

[Simone Briatore]

Hello everyone,

I'm new in this mailing list.

2 weeks ago I bought this device 
http://detail.tmall.com/item.htm?id=36596969793 (the website is in 
chinese), by zhifeng software, which is simply a usb to ISP device with 
an additional reset pin that can be controlled via software. The 
hardware is based upon an atmel microcontroller and few other 
components, and i think is a modified version of the usbasp project 
(http://www.fischl.de/usbasp/)

Since it is very cheap (~2.5$) and it works well (under windows with its 
proprietary program), i want to write down a linux driver (since i use 
linux).
Using reverse engineering methods i came up with a working (with some 
minor bugs) libusb program that can send and receive data through the isp.
Now i would like to insert it in avrdude but i encountered some troubles:

    - I never used avrdude, since i couldn't with my programmer, so i 
just red some tutorials about it
    - I could not find a documentation about implementing a new programmer

Is there some sort of standard way to implement a new programmer in 
avrdude? A sort of API or similar? I searched a little around but i 
didn't find anything...

or

Instead of adding an avrdude component you think is better to create a 
real linux driver and make the device appear as a standard linux SPI 
interface and then tell avrdude to access it? Like a /dev/<something> 
device let's say...

Thank you very much
...and sorry if i did some mistakes but english is not my first language..
