* Code to program an Atmel AVR AT90S device using the parallel port.
|
2000-08-05 05:12:50 +00:00
|
|
|
*
|
|
|
|
* Make the following connections:

* Parallel Port Atmel AVR

|
|
|
* ------------- ----------------------------
|
2000-12-31 02:35:34 +00:00
|
|
|
* Pin 2 -> Vcc (see NOTE below)
|
|
|
|
* Pin 3 -> SCK CLOCK IN
|
|
|
|
* Pin 4 -> MOSI Instruction input
|
2000-08-06 03:53:06 +00:00
|
|
|
* Pin 5 -> /RESET
|
2000-12-31 18:42:42 +00:00
|
|
|
* Pin 6,7,8,9 -> Vcc (Can be tied together with Schottky diodes)
|
2000-12-31 02:35:34 +00:00
|
|
|
* Pin 10 <- MISO Data out
|
2000-12-20 02:26:31 +00:00
|
|
|
* Pin 18 <- GND
|
2000-08-05 05:12:50 +00:00
|
|
|
*
|
2000-12-31 02:35:34 +00:00
|
|
|
* NOTE on Vcc connection: make sure your parallel port can supply an
|
|
|
|
* adequate amount of current to power your device. 6-10 mA is
|
2000-12-31 18:45:53 +00:00
|
|
|
* common for parallel port signal lines, but is not guaranteed,
|
|
|
|
* especially for notebook computers. Optionally, you can tie pins
|
|
|
|
* 6, 7, 8, and 9 also to Vcc with Schottky diodes to supply
|
|
|
|
* additional current. If in doubt, don't risk damaging your
|
|
|
|
* parallel port, use an external power supply.
