Zeile 1: Zeile 1:
The Terminator franchise is what got me interested in the movies in the first place. The first was a suspenseful cyberpunk thriller, and the second became my favorite movie of all time. The third fell short of intelligence but still solid nonetheless, and the TV series was a good addition to the franchise. Nearing the end of May, the fourth and latest film addition of the beloved sci-fi franchise will open, and viewers are in for a sheer summer spectacle.

The Laborboard

The Laborboard is a small board for those of you who want to start programming microcontrollers.

What does it consist of?

The board's core is a ATmega32 controller. There are 4 buttons (Port B) and 8 LEDs (Port C) connected. Additionally there is a 16Mhz quartz oscillator, a reset button and a small circuit to stabilize the supply voltage.

Getting started

You can find a list of the needed parts in this wiki -- Find the component placement specification and circuit diagram here https://www.das-labor.org/trac/browser/microcontroller/doc/Layouts . A lot of example code can be found in our Subversion at https://www.das-labor.org/trac/browser/microcontroller.

Setting fuses

For the controllers to work with the external quartz oscillator and to control the LEDs with all pins on Port C, you have to set the fuses correctly. ATTENTION: SETTING THE WRONG FUSES CAN BRICK YOUR CONTROLLER! The order is important, too: first set hfuse, then lfuse.

...you have been warned. ;)

 avrdude -c bsd -p m32 -t

...some kind of console upens up ...

 write hfuse 0 0xc9
 write lfuse 0 0x9f
 quit

... you should see a confirmation message

If you lack avrdude, you can also use uisp:

 uisp -dprog=bsd --wr_fuse_h=0xc9
 uisp -dprog=bsd --wr_fuse_l=0x9f
