Parport-based Atmel/AVR-programming
Full circuit design and software needed to program AVR RISC controllers
via the parallel ("printer") port.
Please note that I am now using the USB-based
download cable.
Content on this page is no longer maintained/developed.
However, the presented solution is cheap, easy to build and still working
nicely.
Parport-Based Programmers for Parallel and Serial (SPI) Downloading
I am presenting a parallel (historically older) and a serial (SPI) programmer
on the following pages.
Both these devices use the Latch16Bit board,
a simple parallel port device designed by me
(more info...).
Software for the Parport-Based Programmer
Of course, you need a PC-style computer with a (bidirectional) parallel
printer port and some appropriate programmer software.
Fortunately, I am providing the latter one for free under the GNU GPL:
Atmelprg is a programmer tool which can
perform both the parallel and the serial up/downloading of flash and
EEPROM content.
