1/ Generate 3 complementary PWM signals with 3 different duty cycles:
TIM1 input clock (TIM1CLK) is set to 2 * APB2 clock (PCLK2), since APB2
prescaler is different from 1.
TIM1CLK = 2 * PCLK2
PCLK1 = HCLK / 2
=> TIM1CLK = HCLK = SystemCoreClock
TIM1CLK is fixed to SystemCoreClock, the TIM1 Prescaler is set to have
TIM1 counter clock = 18MHz.
The objective is to generate PWM signal at 10 KHz:
- TIM1_Period = (TIM1 counter clock / 10000) - 1
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 25% so channel 2N is set to 75%.
The channel 3 duty cycle is set to 12.5% so channel 3N is set to 87.5%.
The Timer pulse is calculated as follows:
- ChannelxPulse = DutyCycle * (TIM1_Period - 1) / 100
2/ Insert a dead time equal to (100/SystemCoreClock) us
3/ Configure the break feature, active at High level, and using the automatic
output enable feature
4/ Use the Locking parameters level1.
Note:
SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f4xx.c file.
Each time the core clock (HCLK) changes, user had to update SystemCoreClock
variable value. Otherwise, any configuration based on this variable will be incorrect.
This variable is updated in three ways:
1) by calling CMSIS function SystemCoreClockUpdate()
2) by calling HAL API function HAL_RCC_GetSysClockFreq()
3) each time HAL_RCC_ClockConfig() is called to configure the system clock frequency

TIM3 Configuration: Output Compare Toggle Mode:
In this example TIM3 input clock (TIM3CLK) is set to 2 * APB1 clock (PCLK1),
since APB1 prescaler is different from 1.
TIM3CLK = 2 * PCLK1
PCLK1 = HCLK / 4
=> TIM3CLK = HCLK / 2 = SystemCoreClock /2
To get TIM3 counter clock at 18 MHz, the prescaler is computed as follows:
Prescaler = (TIM3CLK / TIM3 counter clock) - 1
Prescaler = ((SystemCoreClock /2) /18 MHz) - 1
CC1 update rate = TIM3 counter clock / uhCCR1_Val = 439.44 Hz
==> So the TIM3 Channel 1 generates a periodic signal with a
frequency equal to 219.72 Hz.
CC2 update rate = TIM3 counter clock / uhCCR2_Val = 878.9 Hz
==> So the TIM3 Channel 2 generates a periodic signal with a
frequency equal to 439.45 Hz.
CC3 update rate = TIM3 counter clock / uhCCR3_Val = 1757.81 Hz
==> So the TIM3 Channel 3 generates a periodic signal with a
frequency equal to 878.9 Hz.
CC4 update rate = TIM3 counter clock / uhCCR4_Val = 3515.62 Hz
==> So the TIM3 Channel 4 generates a periodic signal with a
frequency equal to 1757.81 Hz.

Each time the core clock (HCLK) changes, user had to update SystemCoreClock
