  • Personally I was a bit disappointed with this chip when I read the datasheet compared to when it was first press released. The only thing this chip does is collect the accel data for you so you only manage one I2C, there’s no actual processing. So the Digital Motion “Processing” name is a bit deceptive as the same can be achieved with mcu’s with DMA’s. Granted it does save you some power but for the average user this won’t matter that much with home rockets lasting only a few minutes at best.
    There’s also no provision to do INT triggered read for the external accel, if you read the BMA180 datasheet it will tell you that to get the best performance out of it you should leave it alone until it generates an INT, as traffic on the bus can couple noise into it while its ADC was sampling.

No public wish lists :(
