Hello guys,
i hope someone can help me with this! i have been stuck here for days. I
just created a web app using web2py and i want to use it to send some
serial commands to a device through Raspberry Pi.
I have successfully sent the commands from R-Pi to the device by running a
Python script in the terminal.
But i thought web2py is using python as well so i did something similar but
i get the error below:
*<class 'serial.serialutil.SerialException'> could not open port
/dev/ttyAMA0: [Errno 13] Permission denied: '/dev/ttyAMA0'*
my codes are:
in Controller:
def test():
import serial
serialport= serial.Serial("/dev/ttyAMA0", 9600, timeout=0.5)
return dict() <-- not sure what to return
in view/default/index.html:
<a href = "{{=URL <https://10.0.0.132/examples/global/vars/URL>(c='default',
f='test')}}"><img src ="/Comfort2/static/images/off.jpg" width ="75"
height="75"</a>
i created a default/test.html as well.
i have no idea what's wrong! :( give me some hints please. thank you!
