NDSA USB Console
Connect to the sensor plugged into this Mac with a USB data cable. Open in Chrome. If the sensor's USB chip (CP2102N) is ticked in VMware, untick it first so the Mac can see it.
1. Connect
In the pop-up, pick the port named CP2102N or usbserial.
2. Check the sensor (vendor firmware V1.0)
| Item | Value | Looks |
|---|---|---|
| Firmware | – | |
| Gyroscope zero (°/s) | – | |
| Accelerometer offset (g) | – | |
| Accelerometer matrix | – | |
| Compass offset | – | |
| Compass matrix | – |
3. Set the gyroscope zero
Use the value from the Drift Test page, or type your own. It is saved on the sensor.
4. Identify the processor and flash (changes nothing)
Restarts the sensor into its boot loader and reads what the chip says about itself: processor type and revision, features, crystal, MAC address, flash maker and size. It only reads; nothing is written. The sensor restarts afterwards. The motion chips (accelerometer, gyro, compass) cannot be read this way on the vendor firmware.
