PersonalSoundtrack: Development Blog

The open-source music player that detects your walking or running speed and plays songs from your music library that match your pace. Song speed is adjusted in real-time to match subtle variations in your gait, while larger, deliberate pace changes cause the device to change songs. You simply put it on and begin moving; that's it.

bluetooth is up and running

bluetooth is up and running. i had stripped the filesystem that was stored on the flash memory to almost nothing, so that it would be VERY quickly. pivot-root'ing is very very fast, so the bottleneck is reading the initial filesystem off the flash ram (jffs2 woes).

anyway, turns out the bluetooth has to be enabled in flash filesystem in order for it to be loaded properly. my guess is, i could strip it out of the flash filesystem, and simply have a startup script that runs after pivot-rooting... in fact, maybe i'll do that.

ok so the point is, bluetooth is working!

next goal: offload accelerometer processing and logic onto a pic 16f648a and a PWM accelerometer. i'm a noob when it comes to pic chips, and i'll be writing in assembly (boo). i think i've got the serial code down, i'm going to try to head over to ACE tomorrow and test it out on the pic chip.
