MIDIFighter Source

Im still working on this, just super slowly, hehe, school has started so I havent got much time, Ive been trying to efficiently read a bunch of buttons, I think this may be the hardest thing to do, because the Midifighter latches and shifts, so I cant just steal its code :p
Anyways, I'm still chugging along,

Definatley looking into expanding. . .Keeping an eye out on this. . .but I do have a few questions about expanding (I'm SOOO in over my head on this). . :(

What I'm trying to do is add a few more inputs rather than the standard 4 Digital + 4 Analog buttons. In my case, I'm trying to add a couple more analog inputs (2 arcade buttons, 4 Rotaries, and 2 Faders.)


Will the use of a MUX Breakout board from Sparkfun be okay to expand it a bit further?

did anyone ever port the midifighter source to teensyduino?

If i try to build the firmware i get the following error:

Compiling C: menu.c
menu.c:136: error: expected identifier or '(' before 'const'
menu.c:136: error: expected ')' before '<' token
menu.c:136: error: expected ')' before '?' token
menu.c:137: error: expected identifier or '(' before 'const'
menu.c:137: error: expected ')' before '>' token
menu.c:137: error: expected ')' before '?' token
make: *** [menu.o] Error 1

These are the two lines of code:

inline uint8_t MIN(const uint8_t a, const uint8_t b) { return a<b ? a : b ; }
inline uint8_t MAX(const uint8_t a, const uint8_t b) { return a>b ? a : b ; }


Anyone know how to fix this?

Thank you for helping.

What compiler version are you using?

i use avr-gcc (GCC) 4.3.3

I've tried the old LUFA091122 library and only had these warnings:

Makefile:712: warning: overriding commands for target `doxygen'
LUFA091122/LUFA/makefile:53: warning: ignoring old commands for target `doxygen'
Makefile:717: warning: overriding commands for target `clean_doxygen'
LUFA091122/LUFA/makefile:58: warning: ignoring old commands for target `clean_doxygen'

Hrm, sorry, I have no idea as I am using the same version without problem (on windows).

I assume you didn't change anything related before compiling and that you are using the makefile to build?

Code:

EDIT: I am using LUFA101122

As a matter of interest, cd into the LUFA directory and run "make" (do "make clean" first if its not already clean). Does this build without error?

I've tried the LUFA101122 library and had no more errors.

Thank you.

Great! No problem.

I assume you were using 111009 before? I actually ran into this myself but had forgotten that the midifighter does not currently use the latest version of lufa.

Feel free to get in touch if you have any firmware related questions. I'm pretty familiar with it at this stage.
