analogWrite to PWM pins not working #3
Description
import the lib
from arduino import Arduino
import time
specify the port as an argument
my_board = Arduino('COM5')
print my_board
declare output pins as a list/tuple
my_board.output([9,10,11])
perform operations
i=0
while(i<10):
print 'Writing Value'
val = my_board.analogWrite(11,255)
time.sleep(10)
i+=1
my_board.close()
This code hangs after 'Writing Value'

Have you tried sample_analogwrite.py? It works for me.
Why are you doing val = object.method() anyway? Try my_board.analogWrite(11,255) instead.

Thank you for responding. Yes, I tried sample_analogwrite.py, but the program gets stuck on b.analogWrite(pin, brightness) line. Also, I am not sure why there are two output statements there.
analogWrite method returns a boolean indicating completion. I am just retrieving it be able to see if it was completed properly.

Hm... That's odd. I'm using this lib in one of my projects for several months now (https://github.com/n0w/rgblamp) with no complaints at all. I'm at work now, so I can't test anything but just in case... What version of python are you using? Mine was 2.7 under debian linux

I am using python 2.5 under windows. I think I may have found a work around (I still need to check if it works properly). Looks like it was getting stuck at
" while(self.__getData()!="what"):
pass
"
in arduino.py. So I modified the prototype.pde to the following...
"
int readHexValue()
{
askData();
int strval[2];
int converted_str;
"
Maybe its a windows issue ...
