Nope, it's not namespacing. In python it's safe to just "import serial"
You know the problem is due the "call" function.
Instead using:
* except* ser.SerialTimeoutException:
use:
except serial.SerialTimeoutException:
print('Data could not be read')
except:
print 'Error', sys.exc_info()
And see a better log message.
Don't forget to "import sys"
I belive the problem is the "video_player.py" or the ".mp4" files are
not in /bin. Or you don't have permission in those files...

Keep in mind I am not all that familiar with Python, but have been
programming in multiple other languages since the 90's. Meaning, I
dont write code in Python, but can usually read through it ok.
Anyhow, according to that post this error is due to namespace
resolution. Meaning . ..
*/import serial /*should instead be /*from serial import serial
*/
The second answer although seemingly rewarded with more votes is FUD,
and would be what I'd consider very bad programming technique. Never
name your project the same as an already existing module.

Yeah I saw that, but rushed through it. I'll take a closer look.
Thanks for helping the n00b.

Hey guys,
I'm looking for some help with an error I'm getting. I
think it's just a syntax sorta thing.
Here's my python code:
*import* serial
*import*time
*from* subprocess *import* call
ser = serial.Serial( *"/dev/ttyACM0"* , 9600 )
*while*1:
*try*:
ard = ser.readline()
*if*(*'smile'* *in* ard):
*print**'Smiling'*
call([*"bin/video_player.py -s 80x32 -l bin/smile.mp4"*])
*elif*(*'laugh'* *in* ard):
*print**'Laughing'*
call([*"bin/video_player.py -s 80x32 -l bin/laugh.mp4"*])
*elif*(*'wink'* *in* ard):
*print**'Winking'*
call([*"bin/video_player.py -s 80x32 -l bin/wink.mp4"*])
time.sleep(1)
*except* ser.SerialTimeoutException:
*print*(*'Data could not be read'*)
time.sleep(1)
---------------------------------------------------------------------------------------------------
And here's the error I'm receiving (happens because when I
try to call a subprocess):
File "commands.py", line 23, in <module>
except ser.SerialTimeoutException:
AttributeError: 'Serial' object has no attribute
'SerialTimeoutException'
---------------------------------------------------------------------------------------------------
Thanks for the help!
