I'm currently working on a project which requires more than one PWM signals for my LED drivers.
I'm not looking for any additional hardware for this and so my focus is mainly on software PWM. Based on the example from: http://raspi.tv/2013/how-to-use-soft-pwm-in-rpi-gpio-pt-2-led-dimming-and-motor-speed-control
Has anyone succeeded in creating 3 or more software PWM signals? If so, are there any precautions to be taken by doing this? Your help is much appreciated. :)
