Using the NavChip with fedora
by Ankur Sinha
Hi folks,
It's my first experience with sensors etc.
I'm trying to use the InterSense NavChip[1] IMU (Inertial measurement
unit) sensor with Fedora. Would anyone know how to go about this?
The sensor is detected as /dev/ttyUSB0
I've tried both moserial and cutecom. Cutecom doesn't show ttyUSB0 at
all. Is there a way of "converting" ttyUSB0 to serial, i.e., ttyS*? (Is
this an issue?)
This is what dmesg says on device connection and disconnection:
> [100975.794455] usb 2-1.1: new full-speed USB device number 8 using ehci_hcd
> [100975.881230] usb 2-1.1: New USB device found, idVendor=10c4, idProduct=ea60
> [100975.881236] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
> [100975.881241] usb 2-1.1: Product: CP2102 USB to UART Bridge Controller
> [100975.881244] usb 2-1.1: Manufacturer: Silicon Labs
> [100975.881247] usb 2-1.1: SerialNumber: 0001
> [100975.882402] cp210x 2-1.1:1.0: cp210x converter detected
> [100975.945080] usb 2-1.1: reset full-speed USB device number 8 using ehci_hcd
> [100976.031277] usb 2-1.1: cp210x converter now attached to ttyUSB0
> [102143.137564] usb 2-1.1: USB disconnect, device number 8
> [102143.138220] cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0
> [102143.138251] cp210x 2-1.1:1.0: device disconnected
I've uploaded the reference documents to my fedora people space here[2]
if any one wants to take a look.
The packet format for the sensor is also given in the docs above.
I've also asked a question on stackexchange which has more info (dmesg +
attempts with the sample program that intersense have provided)[3]
(Please feel free to direct me to any documentation for dummies if that
would improve my understanding of the subject)
