| ==The Laborboard==
| |
| The Laborboard is a small board for those of you that 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 [[LaborBoardTeile|parts]] in this wiki -- Find the component placement specification and circuit diagram here ''https://roulette.das-labor.org/svnview/microcontroller/doc/Layouts/'' . A lot of example code can be found in our [[Subversion]] at ''https://roulette.das-labor.org/svnview/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
