I originally voted strongly against analog accelerometers, since then you have to route very sensitiva analog signals half across the PCB. The accelerometers have to be at a maximum physical distance from each other, i.e. there will be long traces with fragile analog signals. Also, each analog accelerometer has three analog signals (one for each axis), which is six signals, i.e. more than our s3c24xx ADC has input channels. Also, having irq-based tap / double-tap / free-fall detection in hardware seemed really neat to me. -- - Harald Welte <[EMAIL PROTECTED]> http://openmoko.org/ ============================================================================ Software for the world's first truly open Free Software mobile phone
