pi@raspberrypi ~ $ sudo webiopi -d -c /etc/webiopi/config 2014-04-05 07:25:43 - WebIOPi - INFO - Starting WebIOPi/0.7.0/Python3.2 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.digitalCount to REST GET /G PIO/count 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.digitalRead to REST GET /GP IO/%(channel)d/value 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.digitalWrite to REST POST / GPIO/%(channel)d/value/%(value)d 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.getFunctionString to REST G ET /GPIO/%(channel)d/function 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.getPulse to REST GET /GPIO/ %(channel)d/pulse 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.outputSequence to REST POST /GPIO/%(channel)d/sequence/%(args)s 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.portRead to REST GET /GPIO/ */integer 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.portWrite to REST POST /GPI O/*/integer/%(value)d 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.pulse to REST POST /GPIO/%( channel)d/pulse/ 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.pulseAngle to REST POST /GP IO/%(channel)d/pulseAngle/%(value)f 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.pulseRatio to REST POST /GP IO/%(channel)d/pulseRatio/%(value)f 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.setFunctionString to REST P OST /GPIO/%(channel)d/function/%(value)s 2014-04-05 07:25:43 - WebIOPi - DEBUG - Mapping GPIO.wildcard to REST GET /GPIO/ * 2014-04-05 07:25:43 - WebIOPi - INFO - GPIO - Native mapped to REST API /GPIO 2014-04-05 07:25:43 - WebIOPi - INFO - Loading configuration from /etc/webiopi/c onfig 2014-04-05 07:25:43 - WebIOPi - INFO - Loading myproject from /home/pi/myproject /python/script.py 2014-04-05 07:25:43 - WebIOPi - ERROR - invalid character in identifier (script. py, line 14) Traceback (most recent call last): File "/usr/local/lib/python3.2/dist-packages/WebIOPi-0.7.0-py3.2-linux-armv6l. egg/webiopi/__main__.py", line 75, in <module> main(sys.argv) File "/usr/local/lib/python3.2/dist-packages/WebIOPi-0.7.0-py3.2-linux-armv6l. egg/webiopi/__main__.py", line 69, in main server = Server(port=port, configfile=configfile, scriptfile=scriptfile) File "/usr/local/lib/python3.2/dist-packages/WebIOPi-0.7.0-py3.2-linux-armv6l. egg/webiopi/server/__init__.py", line 75, in __init__ loader.loadScript(name, source, self.restHandler) File "/usr/local/lib/python3.2/dist-packages/WebIOPi-0.7.0-py3.2-linux-armv6l. egg/webiopi/utils/loader.py", line 8, in loadScript script = imp.load_source(name, source) File "/home/pi/myproject/python/script.py", line 14 GPIO.setFunction(LIGHT, GPIO.OUT) ^ SyntaxError: invalid character in identifier

The config file is like this [GPIO]

Initialize following GPIOs with given function and optional value

This is used during WebIOPi start process

21 = IN

23 = OUT 0

24 = OUT 0

25 = OUT 1

------------------------------------------------------------------------

[~GPIO]

Reset following GPIOs with given function and optional value

This is used at the end of WebIOPi stop process

21 = IN

23 = IN

24 = IN

25 = OUT 0

------------------------------------------------------------------------

[SCRIPTS]

Load custom scripts syntax :

name = sourcefile

each sourcefile may have setup, loop and destroy functions and macros

myscript = /home/pi/webiopi/examples/scripts/macros/script.py

myproject = /home/pi/myproject/python/script.py

------------------------------------------------------------------------

[HTTP]

HTTP Server configuration

enabled = true port = 8000

File containing sha256(base64("user:password"))

Use webiopi-passwd command to generate it

passwd-file = /etc/webiopi/passwd

Change login prompt message

prompt = "WebIOPi"

Use doc-root to change default HTML and resource files location

doc-root = /home/pi/webiopi/examples/scripts/macros

doc-root = /home/pi/myproject/html

Use welcome-file to change the default "Welcome" file

welcome-file = index.html

------------------------------------------------------------------------

[COAP]

CoAP Server configuration

enabled = true port = 5683

Enable CoAP multicast

multicast = true

------------------------------------------------------------------------

[DEVICES]

Device configuration syntax:

name = device [args...]

name : used in the URL mapping

device : device name

args : (optional) see device driver doc

If enabled, devices configured here are mapped on REST API /device/name

Devices are also accessible in custom scripts using deviceInstance(name)

See device driver doc for methods and URI scheme available

Raspberry native UART on GPIO, uncomment to enable

Don't forget to remove console on ttyAMA0 in /boot/cmdline.txt

And also disable getty on ttyAMA0 in /etc/inittab

serial0 = Serial device:ttyAMA0 baudrate:9600

USB serial adapters

usb0 = Serial device:ttyUSB0 baudrate:9600

usb1 = Serial device:ttyACM0 baudrate:9600

temp0 = TMP102

temp1 = TMP102 slave:0x49

temp2 = DS18B20

temp3 = DS18B20 slave:28-0000049bc218

bmp = BMP085

gpio0 = PCF8574

gpio1 = PCF8574 slave:0x21

light0 = TSL2561T

light1 = TSL2561T slave:0b0101001

gpio0 = MCP23017

gpio1 = MCP23017 slave:0x21

gpio2 = MCP23017 slave:0x22

pwm0 = PCA9685

pwm1 = PCA9685 slave:0x41

adc0 = MCP3008

adc1 = MCP3008 chip:1 vref:5

dac1 = MCP4922 chip:1

------------------------------------------------------------------------

[REST]

By default, REST API allows to GET/POST on all GPIOs

Use gpio-export to limit GPIO available through REST API

gpio-export = 21, 23, 24, 25

gpio-export = 21

Uncomment to forbid changing GPIO values

gpio-post-value = false

gpio-post-value = true

Uncomment to forbid changing GPIO functions

gpio-post-function = false

gpio-post-function = false

Uncomment to disable automatic device mapping

device-mapping = false

------------------------------------------------------------------------

[ROUTES]

Custom REST API route syntax :

source = destination

source : URL to route

destination : Resulting URL

Adding routes allows to simplify access with Human comprehensive URLs

In the next example with have the bedroom light connected to GPIO 25

and a temperature sensor named temp2, defined in [DEVICES] section

- GET /bedroom/light => GET /GPIO/25/value, returns the light state

- POST /bedroom/light/0 => POST /GPIO/25/value/0, turn off the light

- POST /bedroom/light/1 => POST /GPIO/25/value/1, turn on the light

- GET /bedroom/temperature => GET /devices/temp2/temperature/c, returns the temperature in celsius

/bedroom/light = /GPIO/25/value

/bedroom/temperature = /devices/temp2/temperature/c

/livingroom/light = /devices/expander0/0

/livingroom/brightness = /devices/adc/0/float

/livingroom/temperature = /devices/temp0/temperature/c

/weather/temperature = /devices/bmp/temperature/c

/weather/pressure = /devices/bmp/pressure/hpa

Same problem ! Anybody can help ?

If anyone runs into this issue it appears there are some illegal characters that in the file if you cut and paste right from the web page. I just went through and at the beginning of each line deleted any spaces and then just hit the tab key until the line was back to its original position. Worked for me and I was seeing exactly the same issue as the first post.
