==== The Kraken ==== Latest rev

{{:kraken.jpg | 400px}} http://farm7.static.flickr.com/6176/6157136371_269ce28736_z.jpg
Schematic is in 032.SVN, Board layout is finished. (built and tested). It has been programmed but USB doesn't ,say hello, is it me you're looking for ? one of the LED's on the test board was faulty and may have caused problems for the CPU since it was basically shorting GND to 5v via a resistor. Swapped cpu to atmega48a, changed zener diodes to 3.6V 500mW usb D+ voltage is good at 3.6V still no go... two resistors were swapped during build... oops....

Useful manual for similar version http://www.protostack.com/download/Users%20Guide%20(AC-PG-USBASP-UG-V1.0).pdf J3 = B = slow clock


 When this jumper is selected, the slow clock mode is enabled. If the target clock is lower than 1.5 MHz, you have to set this jumper. Then SCK is scaled down from 375 kHz to about 8 kHz.

J2 = A = supply target


 If this jumper is bridged, then +5V supply from the USB port will go tho the target device via the ISP VCC connector. Disable this jumper if the target device has its own power source.

J1 = C = self program


 This jumper is used to update the firmware of the Kraken programmer. In order to update the firmware you will need 2 programmers. One to be programmed and the other to do the programming

Using the adapter to connect to a Cylon III

===== First Time Programming ===== Jumper JP2 (underneath


 Set the 5V jumper (connected to VTG pin on 6 pin )
 Set JP2 underneath the CPU ( remove both after programming! 
 Plug into USB

Program as ATMega8(A) with this firmware {{:usbasp.atmega8.2009-02-28.rar}} ATMega8 Fuses


  HFUSE=0xC9
  LFUSE=0xEF

For ATMEGA48(A) use this firmware {{:usbasp.atmega48.2009-02-28.hex.7z}} ATMega48 Fuses


  HFUSE=0xdd
  LFUSE=0xff

Plug into USB

===== Build tips =====

Orientation of the diode.
{{:com_sp_imgc.gif}}
**== Build Instructions ==** 1)Add the 18pF capacitors http://farm3.static.flickr.com/2338/5715492140_b9a35541de.jpg
2)Add the 12MHz crystal http://farm4.static.flickr.com/3214/5715492272_1e9baf5bef.jpg
3) Add the 2.2KOhm resistor http://farm3.static.flickr.com/2346/5714928097_d9686ed152.jpg
4) Add the two 68Ohhm resistors http://farm4.static.flickr.com/3246/5715492562_7f5db88807.jpg
5) Add the 100nF (or 0.1uF) capacitor http://farm3.static.flickr.com/2266/5715492740_182d87aff8.jpg
6) Add the 10KOhm resistor http://farm3.static.flickr.com/2763/5714928883_20f6ca8c8c.jpg
7) Add the ATMega48 chip. The dot on the chip denotes orientation. Make sure to line up the dot on the chip with the dot on the board. The dot should be pointing toward the usb connector. http://farm4.static.flickr.com/3267/5714929221_8060cd6a6d.jpg
8) Add the USB Mini B connector. Make sure to solder down all of the pins in the back of the connector. http://farm3.static.flickr.com/2767/5715493662_5d8c7aa321.jpg
9) Add the 2 MELF diodes. The cathode marks on the diode (as shown in the build tips above) should face each other. http://farm4.static.flickr.com/3393/5715494518_70f92555a6.jpg
10) Add the 4.7uF capacitor. The stripe on the cathode denotes orientation and should be facing the inside of the board. http://farm3.static.flickr.com/2617/5714930475_0be1515af3.jpg
11) Add the two 1KOhm resistors http://farm3.static.flickr.com/2652/5714930583_b95ba65329.jpg
12) Next add the LEDs. Before placing the LEDs it's important to test the polarity since orientation matters for this part. You can test it using a multimeter. Turn the mulitmeter on to the diode setting, as shown below. Take the two leads and place them on the ends of the LED. The purpose of this is to figure out which way the current will flow through the LED, since, like regular diodes, current can only flow in one direction. Once the LED lights up, you will have figured out which side of the LED is the anode (the + side) and which is the cathode (the - side). http://farm7.static.flickr.com/6210/6157554199_6cc9f5afd5.jpg http://farm7.static.flickr.com/6153/6157569801_a44f5697d6.jpg http://farm7.static.flickr.com/6073/6160849446_ac1843399f.jpg 13) You'll want the cathode of the LEDs to face toward the inside of the board (away from the two resistors next to them). The cathode is usually marked with a little green speck. It's important to always check at least 1 LED from a batch since the marking on the LED does change depending on the manufacturer. http://farm3.static.flickr.com/2356/5714930783_43b90eb249.jpg

14) Lastly, add the 2x3 pin header http://farm3.static.flickr.com/2624/5715495570_ac4b91efc5.jpg
Make sure to clean of the board with Flux Remover, rinse off under very hot water and dry it thoroughly. Now you have your own AVR Programmer! ===== Links ===== - [[http://www.fischl.de/usbasp/|USBASP]] Basis for design - [[http://khazama.com/project/programmer/|Khazama]] Programming software - [[http://mdfly.com/newmdfly/products/AVR%20USBISP/USBasp-driver.zip|Windows Driver]] - [[http://download.savannah.gnu.org/releases/avrdude/|AVRDude]] Programming software - [[http://microcontrollershop.com/product_info.php?products_id=2255|10 Pin IDC Cable]] - [[http://www.obdev.at/products/vusb/avrdoper.html|AVR Doper (STK500 compatible)]] - [[http://extremeelectronics.co.in/avr-tutorials/gui-software-for-usbasp-based-usb-avr-programmers/|Extreme AVR GUI]] I recommend either Extreme AVR GUI or Khazama for programming, its a lot easier than AVRDude.. ===== Test Sign drivers ===== [[Test Sign]] Use this to put windows into test mode if you get a yellow exclamation mark on the driver http://www.ngohq.com/home.php?page=dseo
