  7. I'm still struggling to setup my dev env. under Unbuntu 14 (lts) and, i'm facing this problem : when i $ svn checkout svn://svnmios.midibox.org/mios i have no message at all, its just stuck forever, and there's no error, no timeout, nothing. I assumed that the problem was temporary, so i tried everyday since a few days, but no change ... Any idea ? Is there another way to retrieve the svn data ?

  8. Thanks sneakthief ! You were right, and i must confess that i did not search very hard... In common.mk i found this comment/solution : # if MIOS_SHELL environment variable hasn't been set by the user, set it here # Ubuntu users should set it to /bin/bash from external (-> "export MIOS_SHELL /bin/bash") I also found many answer to my problems here : :)

  10. Nice ! I'm also very interested in creating a LED matrix with a PIC18F in C ! I'll try to digest the code, and propose a stripped down version when i find some time. Also i'm curious to know if a 16x16 leds is doable, and what would be the best hardware approach to do so ? Any ideas are very welcome :)
  11. Bonne idee ! Je vais faire ca :)
  12. Bonjour a tous, Je suis a la recherche d'un programmeur, ou plutot d'un service : J'ai quelques (3) chip ATMega48 a programmer, et pas de programmeur sous la main.
