  2. MIDIbox SID V2 Patches

    Hello Midi Bro's, this thread is getting dusty, what a pity ! In the mbsidv2_sysex_implementation.txt - Rev 1190 i read : 02/a) F0 00 00 7E 4B <device-number> 02 00 <bank> <patch> <1024 bytes of dump data> <checksum> F7 Write a dump to <patch> in <bank> Checksum is 2s complement over the 1024 bytes dump Please can someone help me with the Checksum calculation ? (I understand what is the two's complement, but i'm unsure about how to apply it over the 1024 byte dump. And before anyone complain : this is definitely sid-v2-patch related ;) more soon (hopefuly) Thanks !!
  3. Great news ! I'm glad to see that the good old MIOS8 is not completely forgotten, i still love it quite much :)

  6. 7Seg Display and 74HC595

  8. I'm still struggling to setup my dev env. under Unbuntu 14 (lts) and, i'm facing this problem : when i $ svn checkout svn://   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 ?   Also, it would be great to update the wiki application development page, because  "Installing GPUTILS and SDCC on Ubuntu 8.04" is a bit obsolete by now :) (but i have no idea about how to do it)
  9. make with ubuntu

    Thanks sneakthief !   You were right, and i must confess that i did not search very hard...   In 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 :   :)

  11. Led Matrix for older PIC cores in C

    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 :)
  12. Programmeur atmega sur paris ?

    Bonne idee ! Je vais faire ca :)
  13. 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. Est ce que quelqu'un de sympa pourrait me depanner ?     J'ai quelques bricoles midibox a troquer contre le service, eventuellement :)   Merci !!
  14. 5501 Switches (808 style)

    Awesome ! They look perfect ! Thank you Eptheca :D Those ones looks good too :
  15. I'm looking for those button (5501M11) since quite a long time, and i know they are popular among midiboxers, but, they are sooo expensive that i'm very hesitant to buy them. Price is 4 Euro per switch (on mouser), and i need twenty -> 80Euro, only for switches is quite a big budget ! So my question is : does anyone knows some "cheap" alternatives for a similar button ? Thanks !!
