Posted on March 28, 2014 at 10:04Hi,
I have a problem on PWM complementary output by using TIM1 on STM32F407.Now, i am going to drive the 3-phase BLDC with IR2130,
by using the TIM1 timer to generate six step complementary output PWM,
on One step,I wish that the CH1channel can generate PWM waveform, on the same the CH1N channel is High level, but actually, the CH1N channel is always low level!
How can i to setup the library of fuction? thanks!
Now it's my Configuration:
/* Channel1 configuration */
TIM_SelectOCxM(TIM1, TIM_Channel_1, TIM_OCMode_PWM1);
TIM_CCxCmd(TIM1, TIM_Channel_1, TIM_CCx_Enable);
TIM_CCxNCmd(TIM1,TIM_Channel_1, TIM_CCxN_Disable);
CH1 PWM
CH1N H-LEVEL
actuall CH1 PWM CH1N LOW-LEVEL
#pwmoutput
