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, notshift phase
120 degree! Please help me! I use STM32F4 discovery board and Keil! Thanks all2014-10-17 12:13 PM
how we can perform logic AND operation of PWM Channel 1 of TIM1 and pwm Channel 1 of TIM3 internally (using programming)?
Does a reading of the manual even suggest that's possible?2014-10-18 4:53 AM

The pin parameter here is not numeric. GPIO_ReadOutputDataBit()

One of the easiest, simple and functional code samples for timer functionality that I have seen. I changed from toggle mode to PWM1 and it works great. clive1 = Sir Brilliant

hye , clive sir
i am changing the frequency using variable resistor through adc.but when i vary freq. the output of channel 2 and channel 3 toggles. how can i get rid of this toggling???2015-03-07 12:29 PM
I think you'd probably want to change all the settings at the Update, and avoid the preload/immediate functionality.
If you pull in the period any when else, you run the risk of triggering the compares, and causing it to toggle.2015-07-21 5:47 AM
Hi Mr clive1
I have worked through this example code but when I measure phase shifts on oscilloscope I get 60º shift instead of 120º shift?
