Trouble with INPUT pin mode
Hi,
Before explaining the issue I have with your project, let me express how great I find it ! It is doing exactly what I need, thank you !
However I had some troubles when using a pin mode as "INPUT". For instance when running the following simple example :
from Arduino import Arduino
board = Arduino('9600') #plugged in via USB, serial com at rate 9600 board.pinMode(5,"INPUT") board.close()
everything runs fine. However, if I run this same code a second time I get the following output :
File "./TestArduino.py", line 23, in
board = Arduino('9600') #plugged in via USB, serial com at rate 9600 File "/usr/local/lib/python2.6/dist-packages/arduino_python-0.2-py2.6.egg/Arduino/arduino.py", line 106, in init raise ValueError("Could not find port.") ValueError: Could not find port.
But then it works again if I disconnect and reconnect the Arduino. Such an issue is not happening if I replace "INPUT" by "OUTPUT". The versions of Python and python-serial are respectively 2.6.5 and 2.7.
The issue I have is then not a major obstacle since I can just reconnect the Arduino board. But I was thinking that you may want to give this a look.

UPDATE :
This issue is not happening when running with Python 2.7 !
Hi Lucas, Glad you're enjoying the library! Strange issue with rerunning codes in input mode. I'm out of town at the moment, but I'll try and reproduce it & plan a fix when I get home. Thanks for pointing it out! -Tristan On Dec 19, 2013 1:47 PM, "LucasPa" [email protected] wrote:
