4 TROUBLESHOOTING AND FAQ

•
The GUI does not display any
not working, flash the board with the Default firmware using the arrow down button next to the Connect/Disconnect button.
Also, verify that the correct firmware is flashed.
•
Firmware flash produces an error:
Check that the USB cable is plugged into the EDBG port for flashing. Check that the jumper is in the correct position.
•
I reduced the ODR and now the GUI does not display any
high. To fix this issue, 1) go to device manager / Ports (COM & LPT), 2) select your FTDI COM port, 3) right-click on port
properties / Port Settings / advanced 4) in BM Options, set latency timer to 1 ms. 5) reset the board, restart the GUI. You
should now be able to see the signal with ODR set to 10ms.
•
Cliff or floor performance is not
to be accurate by +/- 1mm or +/- 1 degree for best performance.
•
High cliff is not detected: Decrease parameter "Amplitude value to detect far cliff" (steps of 500 recommended)
•
Small cliff is not detected: Decrease parameter "Min cliff depth to detect" (steps of 1 mm) or decrease parameter "Amplitude
value to detect near cliff (steps of 500 recommended)
•
Floor is detected as cliff: Increase parameter "Amplitude value to detect near cliff" (steps of 500) or increase parameter "Min
cliff depth to detect (steps of 1 mm)
•
Hard floor is classified as soft floor: Increase "Threshold hard floor" and/or decrease "Threshold soft floor". Recommended
value: "Threshold hard floor" <= 2x min amplitude of hard floor metric within temporal window of 8 samples.
•
Soft floor is classified as hard floor: Increase "Threshold soft floor" and/or decrease "Threshold hard floor". Recommended
value: "Threshold soft floor" >= 2x max amplitude of soft floor metric within a temporal window of 8 samples.

signal: Verify all connections. Reset the board by pressing reset button on the board. If it is still
good: Verify the physical dimensions of the mechanical device settings. The parameters need
