When I started playing around with this fast, cheap and really nice in-circuit-programmable controllers in 12/98, I had not much to offer:
A link to the Atmel AVR pages and a pointer to the e-Spider AVR programmer from S. Bolt.
Later (12/04/98) I added my AVR-Library for OrCAD (in Rev 9.2 OLB format, zipped)
NEW: You can now find the OrCAD library and Protel99SE library in the 'AVR Academy' of AVRfreaks.com
| | UPDATED (as of March 8,2005) |
| The library now contains: |
| ATtiny12 | ATtiny12small | ATtiny15 | ATiny15small | |
| ATtiny25 | ATtiny26-SO20 | ATtiny26-SO20small | ATtiny26-MLF32small | |
| ATtiny45 | ATtiny85 | ATtiny2313 | ATtiny2313MLF32 | |
| AT90S1200 | AT90S2313 |
| ATmega48-DIL28 | ATmega48-DIL28small | ATmega48-MLF32 | ATmega48-TQFP32 | |
| ATmega48-TQ32 | ||||
| ATmega8-DIL28 | ATmega8-DIL28small | |||
| ATmega8-TQFP32 | ATmega8-TQ32 | ATmega8-MLF32 | ATmega88-DIL28small | |

| ATmega3250 | ATmega3290 | |||
| ATmega64 | ATmega645 | ATmega6450 | ATmega6490 | |
| ATmega128 |
still in there are some obsolete and EOL issued parts:
| AT90S2333 | ||||
| AT90S4414 | AT90S4433 | AT90S4434 | ||
| AT80S8515 | AT90S8535 | |||
As you might have noticed, most of the devices come in different housings and ‘flavours’. Some people prefer to have the ports sorted, some (mostly the ones doing their own layouts) prefer to see the real pinning of the chip. I hope I have something for everyone. Of course I can add your favourite view of the parts if you send it to me :-)
Please let me know if you find this LIBs useful. I'm especially interested in a copy if you modify it or make additions.
Please let ma also know if you find any errors.
Here some hints and links (see also my link page):
Some of my AVR projects:
(There are more, but they are customer specific designs and I'm not allowed to publish them - among them things like power surveillance, train network nodes etc.)
In model rocketry (one of my other hobbies) one must eject a parachute at (or near) the apogee
in order to have the rocket return to earth without endangering people or property and in a reusable
shape. And of course it is interesting, how high the rocket went.
Rocketry instrumentation can use various sensors (barometric, innertial, magnetic field, ...) and timers. So it
seems natural to build every kind of electronic rocket gadget while learning a new embedded processor like the AVR.
| Altimeter for hobby rocketry (AT90S2313) | |
|
During a rocket flight, this altimeter reads barometric data and stores it 10 times
per second in an 8K EEPROM until apogee is detected (when pressure starts to rise again).
Then a MOSFET output is activated to trigger a pyrotechnic ejection charge for a parachute. An
optional second channel can be used for dual recovery (small drogue first and main
parachute later for soft landing without too much drift).
|
| Rocketry Timers (AT90S2313) | |
 Picture 1 Picture 2 Picture 3 |
Annother method to time parachute ejection is, well, a timer.
|
  |
Later I modified the design for 2 independent channels.
|
|
For very small model rockets or as a backup timer that should find a place
in almost every rocket I designed the TinyTimer:
|
| µBrain88 - A small "brain module" for various projects | |
|
|
| DDS synthesizer | |
| ... |

Please stop by again later, as new parts will be added...
