This is documentation for a simple open-source USB AVR programmer and SPI interface. It is low cost, easy to make, works great with avrdude, is AVRStudio-compatible and tested under Windows, Linux and MacOS X. Perfect for students and beginners, or as a backup programmer. The project is based off of the USBtiny code & design. Jul 7, 2014 - Download AVRdude GUI for free. A GUI Interface for the popular avrdude program. Written in C++ using. Software Development.

AVRISP/STK500v2 compatibility bridge There's already lots of good software for programming and debugging AVRs, such as (the official development software from Atmel). However, AVRStudio only really supports and programmers (the official programmers). Since there are many times when you may want to use AVRStudio, I've written some software glue that will let you use your USBtinyISP in STK500/AVRISP compatibility mode. Notes Nearly all of AVRISP (STK500v2) functionality is emulated at this point. • Oscillator calibration is not implemented at all, due to hardware constraints.

That is, a 400KHz ISP clock just means that at most, it will be clocked at 400KHz.

In reality it's often slower due to the programmer coping with USB stuff. For general development, I strongly suggest using as this is a bit slower and is probably flakier. Please note, this software is in alpha. Your reports, comments and suggestions are appreciated! (post it in the ) If you send a bug report please let me know which chip you are using and what specifically is failing. COM bridge The AVRISP, which we will be emulating, usually connects to a PC through the serial (COM) port.

The trick here is to install a COM bridge, a piece of software that makes two virtual COM ports that are hooked up to each other so when you write to one it appears on the other. The compatibility software sits on one COM port, pretending to be a AVRISP while the AVRStudio software talks on the other, thinking that it's connected to a genuine programmer! You'll only have to install this software once.
