python - Time management for real-time applications -

how generate precise pulses python?

from threading import thread import time  def runa():     while true:         print "a"         sendsignal(1)         time.sleep(0.0001)         sendsignal(0)         time.sleep(0.005)   if __name__ == "__main__":     t1 = thread(target = runa)     t1.setdaemon(true)     t1.start()     while true:         sleep(10) 

time management in python not precise. specially create multi-threaded pwm generators (assuming each thread send data @ specific rate) . there better way generate pulses? precise ones!

[the solution language-independent]

my solution find real-time os raspberry pi have real-time patch raspbian os

was little of challenge enable it. working , error rate dropped dramatically.

thank @holdenweb tip real-time os
