Parallel Port Programmer

AVRISP is a 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 the parallel port. The programmer on a parallel port is much simpler than connected to a serial port because there is no needed voltage adapter like MAX232. You can only

The printer port pins and the programming configuration options on the FPGA are set up for the 'parallel slave' configuration mode. This allows very fast download of the programming data since even though the PC must use bit-banging for accessing the chip, data is pushed out one byte at a time.

This is the simplest circuit with which AVR Atmega series, Attiny series, AT90S series microcontrollers can be programmed. There are a lot of programmers available, but this is a simple one which you can make it with just few wires and a 25 pin parallel port connector . First check for the parallel port in your computer.

A parallel port programmer looks something like this It plugs into the parallel printer port of a computer . You can see the silver part plugs into the parallel port, and then theres a cable that plugs into a 10-pin ISP header. A serial port programmer looks something like this Very similar to the parallel port programmer, but plugs into

Parallel Port Programming. An article from Hasha Perla. External Parallel Port devices and Linux. Many links and info. From Tim Waugh. If you have a usually old device that sends data to a line printer, and you want to instead read the data into a PC, buy or make a parallel-to-serial converter and read the data at a serial port, using a

All steps are same as described in parallel port programmer section, However during third step do the following settings select quotserialquot, from list select quotSI prog IOquot, select quotCOM1 usually serial port is at COM1, if your computer have more than one serial ports multiple options will be active.

3. For a Read operation, if the PC's IO port lines amp378 are now SET as an input, use the 37A IO lines to do a EEPROM Read. 4. If your PC's Parallel port 378 cannot be made a Read as well as a Write, you will have to Read two nibbles, using the 257 and the parallel port 379 four 'In' lines.

1x parallel port cable or parallel-to-serial adapter 2x three wire cables with female connectors on one end, unattached wires on the other Programmer parts. Instructions. Remove any existing wires from the parallel connector. Solder 470 ohm resistors to pins 1 and 2 of the parallel connector. Soldered resistor

quotThe EMP-20 programmer is an inexpensive, portable, parallel port programmer that was designed from the ground up to be fast and versatile. It easily connects to your PC through a standard parallel port.quot The EMP-20 uses plug-in quotfamily modulesquot to configure the programmer for different devices.quot Each family module supports an entire family of

Parallel Port Programming PART 1 with C. By HarshaPerla . Parallel port is a very commonly known port, widely used to connect the printer to the PC. If you see backside of your computer, there will be a port having 25 pins with a small symbol like this. That port is known as LPT port or printer port.
