synchronising sound with movements

2010-05-24T20:14:06+01:00

Looking the firmware - i think the sound chip is a BMC504

This is based on the 8051 CPU it has 4Mb of Flash for sound storage - and is designed for both voice recording and sound output - so it may well be possible to upload wav files into the flash for playback via the serial bus. The sounds that come with it though must be pre-configured as the firmware doesn't upload them as far as I can see.

I don't believe this its possible even in firmware as the sound chip seems to only supports pre-defined sounds. (does anyone have details on the chip?)

Certainly the controller spec also suggest this-

The sound chip is controlled by the CPU using wck bus.

However, there is a direct output from the CPU - PWMSND (port E/3) - (volume control?) which I presume means you could build your own sound routines in firmware - from the ground up. May be

There is certianly no interface to do this in any of the moltion/actionbuilder software, so unless there is a hidden protocol to download it to the RBC brick I think you will need to modify the firmware.

The RBC is actually very hackable, you should be able to use avr-gcc and avrlibc to compile the sample robobuilder firmware and make a few quick changes to the way that sounds are played (if you can decipher their source ). And don't worry about bricking your brick - you can easily restore the old firmware using the RBC firmware upgrade tool. All the documentation is here.

synchronising sound with movements

2010-05-06T19:34:41+01:00

hi,
i am new to working with robobuilder, i have a 5710K and would like to synchronise movements with my own sound files.
i've found the list of the 25 sounds detailed in the rbc serial protocol documentation. i've also found an example in the microsoft robotics dev studio user guide.
can anyone suggest a simple way to do this?
am i right in thinking that to replace the 25 default sounds i would have to edit the firmware? it's just that i would still like to use motion/actionbuilder software..
thank you-
kirsty
