• Drive dot LED matrix display using LPT port and driver IC
  Interesting projects on how to drive multiple dot LED matrix displays using LPT port and Led matrix driver cirtuits. Step by step explanation how to start your own system.
  It is convenient to drive dot LED matrix displays using IC drivers of 5×7 dot LED matrix’s like MAX6952 and MAX6953. These two IC’s differ only by data interfaces: SPI for MAX6952 and I2C for MAX6953. In this article you will se how these driver IC’s can be controlled by computer using LPT port.Program provided [...]

• AVR ISP programmer using LPT port
  Simple AVR microcontroller ISP programmer that connects to PC LPT port. Works with PonyProg .
  AVRISP is very popular Parallel port programmer for flashing AVR type microcontrollers. Earlier I used programmer connected to com port, but frequently I needed this port for other purposes, I decided to make it work on parallel port. The programmer on parallel port is much simpler than connected to serial port, because there is no [...]
