The 210/109 combination allows for a register set to select 1666 Hz. If I run the device and do a read only, it may almost run at 1666 Hz, but if you do any real reads and analysis wanting the acceleration, time and frequency the device runs slower
I have about 10 of these devices on about 6 computers, so this problem is common, the device runs at about 1200 to 1400 Hz. The picture shows a temperature, frequency and FFT results plot for one device. The typical is about 1400 +- 50. I take and...
