On-line measurement
Off-line measurement
Read out data from Flash
During on-line measurement, data is read from MEMS and sent via USB to the PC.
Logically, all three LEDs should blink. In this mode, the buttons have the following meanings:
●
●
●
●
Ready to start the measurement. Normally LED7 blinks.
●
●
●
●
Ready to start sending data stored in Flash via USB. Normally LED7 is blinking.
●
●
no button is pressed
uPSD sends data from MEMS to the PC (a packet with MEMS data)
BUT5 is pressed
No effect.
BUT6 is pressed
No effect.
BUT7 is pressed
In the case of digital MEMS, uPSD reads its registers and sends this information via
USB (a packet with registers)
no button is pressed
No effect.
BUT5 is pressed
Pause/Stop measurement.
BUT6 is pressed
Start measurement, LED5 blinks to indicate data is being read and stored (it stops
automatically when the Flash is full).
BUT7 is pressed
If measurements have not started, the sample frequency can be changed. Possible
frequencies are 40 or 160 Hz. The selection is indicated by the LED7 blinking speed.
Off-line measure time
no button is pressed
No effect
BUT5 is pressed
Start sending data. uPSD sends data from Flash and LED6 blinks (a packet with
MEMS data). It reads the entire Flash. Any part which doesn't contain relevant MEMS
data you will get 0xFF. After the end of the Flash range, 0xFF will also be sent. 0xFF
