This example shows how to configure the TIM1 peripheral to generate three complementary TIM1 signals, to insert a defined dead time value, to use the break feature and to lock the desired parameters.
The system clock works at 96Mhz and is generated through PLL configuration. The PLL clock source is an external 8Mhz crystal oscillator. The frequency division ratio of APB1 is 1, and the frequency division ratio of APB2 is 1.
TIM1CLK is fixed to SystemCoreClock, the TIM1 Prescaler is equal to 0 so the TIM1 counter clock used is SystemCoreClock.
The objective is to generate PWM signal at 1.46 KHz:
-TIM1_Period =(SystemCoreClock / 65536)
The Three Duty cycles are computed as the following description:
The channel 1 duty cycle is set to 50% so channel 1N is set to 50%.
The channel 2 duty cycle is set to 50% so channel 2N is set to 50%.
The channel 3 duty cycle is set to 50% so channel 3N is set to 50%.
A dead time equal to 11/SystemCoreClock is inserted between the different complementary signals, and the Lock level 1 is selected. The break Polarity is used at High level.
In order to make the program work, you must do the following :
