The Laborboard[Bearbeiten | Quelltext bearbeiten]

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

What does it consist of?[Bearbeiten | Quelltext bearbeiten]

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[Bearbeiten | Quelltext bearbeiten]

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[Bearbeiten | Quelltext bearbeiten]

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

pin assignment of the programming plug[Bearbeiten | Quelltext bearbeiten]

       +-----+
   GND | 0 0 | MISO
   GND | 0 0 | SCK
   GND | 0 0   RESET (inv)
   GND | 0 0 | (not assigned)
   VCC | 0 0 | MOSI
       +-----+
