* fit-statUSB provides status indication by changing the LED color, brightness and color cycle.
* fit-statUSB identifies to the PC as a serial device and changes the LED color by text commands received over the serial port.
* See [https://fit-iot.com/web/product/fit-statusb/ fit-statUSB product page]
== Commands ==
=== General ===
Commands to fit-statUSB are sent over serial port. No need to configure the baudrate, fit-statUSB adjusts automatically.
Each command ends with a LF and executed immediately.
=== Set color ===
#RRGGBB
* RR | GG | BB - HEX value of red, green, blue respectively
fit-statUSB will set the intensity of each of the colors.
'''Examples:'''<br>
To set dim green
#001200
To set bright yellow combine red and green
#FFFF00
=== Set color sequence ===
Set a sequence of alternating colors. The sequence will cycle endlessly until a new color command is entered.
B#RRGGBB-tttt#RRGGBB....
* RR | GG | BB - HEX value of red, green, blue respectively
* tttt - time until next color is displayed
'''Examples:'''<br>
Pulsing red color
B#FF0000-0200#000000-0600
Alternating red-blue
B#FF0000-1000#0000FF-1000
Cycle of red 0.1 sec - yellow 0.1 sec -white 1 sec - off 0.3 sec
B#FF0000-0100#FFFF00-0100#FFFFFF-1000#000000-0300
=== Set color transition period ===
Set how quickly current color fades to the next color.
Fnnnn
* nnnn - transition time in mS. Permitted values: 0001 (immediate) to 9999 (slowest transition, 10 seconds)
Transition period is persistent until a new F command is entered. <br>
For B command the F value will determine transition period between colors.
=== other (less common) commands ===
* P - Enter Device firmware update mode
* ? - Return device UUID #
* G - Return current color, (rr,gg,bb)
== Using fit-statUSB in Windows ==
=== From Drivers ===* [https://fit-iot.com/files/download/accessories/fit-statusb/sw/Win7/msp430_ti_signed.inf Fit-statUSB Windows 7 driver]* [https://fit-iot.com/files/download/accessories/fit-statusb/sw/Win8.1/msp430_cdc.zip Fit-statUSB Windows 8.1 driver]* Additional drivers are not required for Windows 10 operating systems === Using fit-statUSB from terminal ===* Open a terminal utility with serial port support (e.g. [https://ttssh2.osdn.jp Teraterm])* Establish new connection to the serial port assigned to fit-statUSB (in TeraTerm: File --> New connection --> Serial (select COMn: USB Serial Device)* Type a command, e.g. #FF0000 (fit-statUSB should turn RED)Note there is no command editing (no backspace / delete). If you mistype please start a new command.=== Using fit-statUSB from command line ===
echo [command] > \\.\[com port]
* [command] - the command sent to fit-statUSB over serial
=== Detect COM port of fit-statUSB ===
==== From Device Manager ====
Under device manager | Ports (COM & LPT)<br>
look for
USB Serial Device (COMn)
* n - COM port number
==== From command line ====
To identify which COM port is assigned to fit-statUSB use '''mode''' command
mode
Assuming fit-statUSB is on COM10 the following command will set fit-statUSB color to red:
powershell "$fitstatUSB= new-Object System.IO.Ports.SerialPort COM10; $fitstatUSB.open(); $fitstatUSB.WriteLine('#FF0000'); $fitstatUSB.Close()"
== Using fit-statUSB in Linux ==
=== Using fit-statUSB from terminal ===
==== Using Bash Command line ====
* First you need to configure the Serial port
sudo stty -F /dev/ttyACM0 9600 raw -echo -echoe -echok -echoctl -echoke
* Send the command directly to the TYY port
echo "B#FF0000-1000#00FF00-500" > /dev/ttyACM0
- Please note that some Linux distributions will require sudo privileges to echo directly to serial
==== Sample Python code ====
* Python dependencies: pyserial
import serial<br>
ser = serial.Serial("/dev/ttyACM0")
ser.write(b"B#FF0000-500#00FF00-500#0000FF-500\n")
ser.close()
- Note that new line must be addded at the end of the command String
=== Detect fit-statUSB Serial Port ===
To Detect the system assigned TTY device:
sudo dmesg
Look for fit_StatUSB String and its assigned TTY device
