[ARCHIVE] A project from Ivan A Gritskov from Russia.
Synoptic.
working.
Ivan has used the Atmel DC-CDI originaly designed for a XT600, and modify it in order to fit a DRZ400S.
He also used a Tiny2313 which has the same pinout a 89C2051, except the Reset pin which work in a opposite way.
The software has been re-writed using BASIC-AVR and the advance curve has been changed too.

Compare to 89C2351 version, there are 4 differences:
IC3 at89c2051 -> attiny2313 crystal 24MHz -> 20MHz C5 (22uF 16V) -> 1k resistor R15 (4,7k) -> 0.1uF capacitor

Beatifull simplicity, I’am working in a DC-CDI for my Suzuki Bandit 400. I’ll take this design as a base. Gosh I want to learn russian!
Congratulation.
Hello, i really like this CDI Ignition but i cannot find the necessary transformer. Can you give me more information about it? Thank you very much, greeting from Slovakia 🙂
Hi,
You can find references at transformer section in this other DC-CDI:

Hi, thanks for the transformer, but I also want to ask, what is the correct fuse settings for the ATtiny?
Sorry , I wasn’t my project. I don’t know. Perhaps there is more information on the forum http://bascomavr.3bb.ru/viewtopic.php?id=449
