  • I am trying to communicate with the BMA180 with SPI. Is there any command I can send that will return a known output so that I can know if I am data correctly.
    Is it right that you send a 1 followed by 7 bits which are the register number that you want to read?

  • I would like to see a chart of the output voltage vs loads of the 5 volt switching wall wart that Sparkfun sells. While I have no doubt that it would be a lot better I wonder how much variation there would be say from 100 ma draw to 1000.

No public wish lists :(
