Hello. I’m trying to get through some tutorials on the website. Data-sheets are displayed in the tutorials. I’m wondering, where do they come from?
For example: in Tutorial #2, the ports for the AVR STK Parallel Port Dongle Programmer is not fully shown. Searching on atmel.com’s site for the cable doesn’t bring up any documentation.
What is the best way to find technical documentation for micro-controllers, cables, etc…?
Also, does anyone know of a resource that explains the different acronyms, in the schematics, such as PCK, PCInt, MISO/MOSI, etc…? Its bothering that I have no idea what these things mean while I’m doing the tutorial.
I think I know pretty much how you feel. Usually when I’m floundering around looking for a solution, all I can turn up are more questions.
In your particular case, it would probably be more appropriate to re-post your question in the comments area after the tutorial.
I’ve not looked at any AVR datasheets in a while, but I presume they are still very thorough. All the signal names you mention are surely described in the ATmega168 data sheet, as well as details on what goes on at the ATmega end of the dongle.

here and for Atmel, the avrfreaks.net forum. On the latter are some good intro books.
Recommendation: Don’t struggle with parallel port ISP (flash programmers).
The NXP LPC family of ARM7, and others I suppose, have a factory-installed serial port bootstrap loader you can use instead of ISP or JTAG.
MISO and MOSI are the names of two of the Serial Peripheral Interface (SPI) standard. The microprocessor’s data sheets/specs would tell you this.
Though this forum area is ARM, you mention AVR - the 8 bit Atmels, as popular on avrfreaks.net.
