Simplest and low cost USB AVR


Posted on Feb 6, 2014

This is the low cost AVR programmer using attiny2313. The schematic diagram is given below. First setup the circuit as shown. One important care taken to make fuse bit avrdude -c usbasp -p t2313 -U hfuse:w:0xdf:m -U lfuse:w:0xef:m If you use serial port to write the program , use stk200 command instead of usbasp.

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 underWindows, Linux and MacOS X. Perfect for students and beginners, or as a backup programmer.

The project is based off of the USBtiny code & design. The main improvements are: adjusting the code to allow it to act as a SpokePOV interface, adding lowlevel bitbang commands, and addition of a "USB good" LED. Other changes are new VID/PID (to make it official), removing some of the commands, and moving around the pins a bit.
