Hi all!

I want to control 3 phase motor (I get HDD motor from old HDD), and now I can generate 3 PWM signal on 3 channels but they are same, not

shift phase

120 degree! Please help me! I use STM32F4 discovery board and Keil! Thanks all

Ok, the toggle only deals with half a cycle.

You'll need to play with the Pulse settings, and to get to 240 degrees you might need to invert the initial phase/state of things beyond 180
