Have you tried power cycling the "bad shimmers"? If you've used shimmer-connect, you may have noticed an 8 second delay in the beginning of gyro transmission.
The IDx500 series gyros are sensitive to power-up not being monotonic. This situation occurs during the BSL process due to the pins I picked on the duaghterboard (oops) and for legacy reasons we're staying with them as the fix is easy. 1) add 8 seconds of gyro "off" time before enabling gyro power at the beginning of your app. 2) manually power down shimmer (with power button on dock/shimmer) after using BSL. -Ben On Thu, Sep 6, 2012 at 10:45 AM, Rahav Dor (yahoo) <[email protected]> wrote: > I have modified JustFATLogging to read the Gyroscope as well.
