   As it seems there is no distributor for gradconn that would sell low quantity. 1500 seems to be the minimum. *sigh* !electronics !obldc

   I think I found the connector used on Turingy dlux controllers. http://ur1.ca/49d3z They are even length .5mm pitch. :( !electronics !obldc

   The Turingy dlux logic to powerstage connector is different then the one used on Castle. Need to source it somewhere. !electronics !obldc

   Finally the Turingy dlux 55A arrived. They are very similar to Castle. http://ur1.ca/498jn !electronics !obldc

   Since !libopenstm32 now has CAN support I can finally port !obldc to it! !stm32 !opensource

   Some pictures of the new !obldc logic board clogic v0.1 that mounts on Castle Creations ESC power stages http://ur1.ca/2d4cw !electronics

   New !openbldc prototype logic mountsing on Castle powerstages sent out for prod., now we have a big choice of configs. http://ur1.ca/2778w

    Got hardware based commutation detection and closed loop control running in !obldc http://ur1.ca/1oa75

    An important new doc page for !obldc how to build the firmware yourself https://open-bldc.org/wiki/Developer_getting_started

    So after finishing the first stab at documenting !obldc source using doxygen now it is available online http://doc.open-bldc.org

    Thursday, 19-Aug-10 01:35:33 UTC from Adium
15. Piotr Esden-Tempski Open-BLDC

    Finally added doxygen to !openbldc firmware build system. I should have done that ages ago. So many things that need to be documented. >_<

16. Piotr Esden-Tempski Open-BLDC

    Added sys tick based general purpose timer system to !obldc codebase. That was easier then I expected. Let's use it for motor "ignition" :)

    New blogpost on !obldc v0.3 hardware http://www.esden.net/blog/2010/08/05/open-bldc-v0-3/ and some pictures of it http://ur1.ca/119ud

    The full !obldc v0.3 stack works electrically, now bringing up the subsystems one by one. ;)

    Working on !obldc v0.3 boards. It is really funky when the external clock works the jtag interface fails and the other way around >_<

20. Piotr Esden-Tempski Open-BLDC

    Sweet I managed to connect !obldc v0.2 logic board to the v0.1 powerstage, since there is no v0.2 pstage and the new v0.3 is in development
