(The third wire is not used and may be cut short). Solder the middle wire of the second cable to the resistor on pin 2 (which goes to pin 17 on the Atmega8), and one of the other wires to pin 18 (which goes to ground). Parallel connector with two of the three wires of a cable soldered to pins 11 and 1, respectively. Solder, in order, the three wires of one of the cables to the resistor on pin 11 (which goes to pin 18 on the Atmega8), to the resistor on pin 1 (which goes to pin 19 on the Atmega8), and directly to pin 16 (which goes to the reset, pin 1). Solder a 220 ohm resistor to pin 11 of the connector. Parallel connector with a 470 ohm resistor soldered to pin 1. Solder 470 ohm resistors to pins 1 and 2 of the parallel connector. Remove any existing wires from the parallel connector.

(2x) three wire cables with female connectors on one end, unattached wires on the other.

(1x) parallel port cable or parallel-to-serial adapter.

(2x) 470 ohm resistor (yellow-purple-brown).

(Please note, however, that this doesn't allow for communication between the computer and programs running on the board. Allows you to program the board on Windows without any additional equipment.

On most computers there is usually only one parallel port available which can cause many headaches if that port needs to be shared with a printer or scanner.Instructions for building a parallel port programmer for the Arduino board (or any other Atmega8 chip). Most manufacturers have different implementations of the parallel port. And good luck trying to use the parallel port on your laptop computer. Often times, users of the parallel port will run into OS issues or BIOS issues. The most significant issue is that the port is non-standard. The Parallel port can be fast enough for most applications, but it suffers from many problems. If you have a host adapter that claims to support 400 kbps, consider the fact that the serial port can only support 115 kbps. The serial port is the slowest of the group. The real problems are: bandwidth and limited ports. The behavior of the serial port has been standardized across computers so there are no surprises there. The serial port does not suffer the same problems of the parallel port. Practical max length is 1m.Ĭable can be of any length as long as electrical spec is met. Yes, can provide up to 900 mA at 5V (Also USB Power Delivery)Ĭable can be of any length as long as electrical spec is met. Limited to the number of ports available on the computer. Here is how USB stacks up against other protocols available for other host adapters:

Additionally the Promira Serial Platform includes a 1 Gigabit Ethernet port. USB is the standard for connecting peripherals to your computer. Total Phase is pleased to offer USB on all its devices.
