Here's AVR programmer for programming AVR microcontrollers such as the AT90S1200 via the parallel port. AVR programmer is extremely simple. IC1 provides buffering for the signals that travel from the parallel port to the microcontroller and vice versa. This is essentially everything that can be said about the circuit. The two box headers (K2 and K3) have the ‘standard’ ISP (in system programming) pinout for the AVR controllers. The manufacturer recommends these two pinouts in an attempt to create a kind of standard for the in-circuit programming of AVR microcontrollers. These connections can be found on many development boards for these controllers. The software of AVR programmer carries out the actual programming task.
