I was showing off my tuxdroid at the Dallas area unix group and I
realised that there was no function to play sounds so I went browsing
in the firmware source code. The patches are attached.
See
http://www.tuxisalive.com/documentation/how-to/remote-control-standaloneby
just pushing buttons (no computer or dongle involved).
I decided that the colour keys would be suitable and tried a stored
sound to each one and ended up assigning a behaviour (like when you
connect the power or turn tux on).
In the tuxcore code, the file standalone.c contains a switch statement
that describes what should happen when the remote sends a key press. It
looks like this:
switch (ir_command)
{
case K_0:
COMMAND;
break;
}
with a case for each key code.
So I added cases for K_RED, K_GREEN, K_BLUE and K_YELLOW, something
like this:
case K_RED:
launchActions((const uint8_t*)&tux_k_red_e);
break;
tux_k_red_e describes what should happen when the red button key code
is received. There is one for each key.
In config.c, I added an entry for tux_k_red_e:
uint8_t tux_k_red_e[LONG_EVENT] EEMEM = TUX_K_RED_E_SEQ;
and in common/config.h, I added a description of the sequence:
/* Actions on Red Button */
#define TUX_K_RED_E_SEQ {\
10, PLAY_SOUND_CMD, 3, 0, 0, /* play a sound */\
10, MOVE_MOUTH_CMD, 2, 0, 0,\
END_OF_ACTIONS\
}
The number after the sound cmd is the index of the stored sound to be
played. I don't know what the number at the start of each line is for.
A few lines need to be added to the config.h in tuxcore (not the one in
common/):
/* Demo sequences on remote colour keys */
extern uint8_t tux_k_red_e[];
After I compile everything, upload it to the tux and try it out, I find
it mostly works. For some reason, even though all the behaviour
sequences look alike except for the sound number, Tux doesn't always
want to play when the red button is pressed, but works on the other
keys. Also, the eyes don't light when Tux is powered on and he makes
no noise.
Another oddity is that the mouth movements and wing flappings occur at
different times for each colour, but occur consistently at those times.
I have attached patches in case they are of interest:
demo_h.patch - patches config.h.
demo.patch - patches common/config.h
demo_c.patch - patches config.c and standalone.c - if this patch is not
applied, the patches to the .h files have no effect.
