Make your own universal AVR programmer (parallel port)

Two types of AVR programmers can be built :

1) serial port.

2) parallel port.

PARALLEL PORT 

Following circuit diagram shows ultra simple AVR microcontroller (SOURCE: unkown). It requires very few components and its very simple to build on general purpose matrix PCB. You can use PonyProg2000 software to program your AVR using this programmer.

NOTE: 

The ponyprog2000 software is found in the following link:

CIRCUIT DIAGRAM :

LIST OF COMPONENTS :

1)Resistors	220Ohms ,1/4W	4
2)Capacitors	27pF,disc	2
	1µF , electrolytic	2
3)Crystal	4Mhz OR 8Mhz	1
4)Voltage regulator	7805	1
5)Connector	D25 Male	1
6)Grid PCB	3″ x 3″
7)Connecting wires	-	-

• As programmer circuit is very simple, u can use substitutes if particular component is not available at your place.
• You will not get 3”x 3” GPCB ready made, you have to cut standard sized PCB. 3” x 3” is just rough estimate

CONFIGURING AND USING PONYPROG2000 :

1. Open PonyProg2000
2. Select menu : Setup>Interface Setup
3. Select “parallel”, from drop down box select “Avr isp i/o”, select “LPT1″. Click OK.

     4.Now select menu Setup>Calibration. A dialog box will appear , click YES.

     5.Now PonyProg2000 is configured and ready to use.

     6.To burn your .Hex file into micro, select File>Open Program(FLASH) file.

     7.Select appropriate microcontroller from the list of devices at top-right. e.g >

      8.Connect your programmer ckt to PC, then place your micro into programmer ckt and turn on its power supply.

      9.Now click on the encircled icon :

        10.When device is programmed you will get “Program succesful” message.
