Example Description

This example shows how to configure the TIM1 peripheral to generate one complementary TIM1 signal, 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 96MHz，the TIM1 Prescaler is equal to 0，so the TIM1 counter clock used is 96 MHz.
TIM1 frequency = TIM1 counter clock / (TIM1_Period + 1) = 1.46KHz。
TIM1 Channel1 duty cycle = TIM1_CCR1 / (TIM1_Period + 1) = 50。
TIM1 Channel1N duty cycle = (TIM1_Period - TIM1_CCR1) / (TIM1_Period + 1) = 50。
A dead time of 100 / 96Mhz is inserted between the different complementary signals, and the Lock level 1 is selected. The break Polarity is used at High level.
The TIM1 waveform can be displayed using an oscilloscope.

Hardware and Software environment

- Hardware environment
  - HSE crystal is 8MHz
  - Connect the TIM1 pins to an oscilloscope to monitor the different waveforms:
    - TIM1_CH1 pin (PA.08)
    - TIM1_CH1N pin (PB.13)
  - Connect TIM1 break pin TIM1_BKIN pin (PA.06) to the VCC to generate Break。

How to use it ?

In order to make the program work, you must do the following :

- Open TIM_TIM1ComplementarySignals.uvprojx from this example folder by Keil MDK5
- Rebuild all files and load your image into target memory

- Run the example
