@par Example Description 

This example shows how to configure the TIM1 peripheral to generate 7 PWM signals 
with 4 different duty cycles (50%, 37.5%, 25% and 12.5%).

In this example, Main clock is from PLL clock and it is configured at 72MHz. The PLL clock is based on 12MHz HSE. APB1 and APB2 clock is from Main clock.

The objective is to generate 7 PWM signal at 1.09 KHz:
  - TIM1_Period = (SystemCoreClock / 17570) - 1
The channel 1 and channel 1N duty cycle is set to 50%
The channel 2 and channel 2N duty cycle is set to 37.5%
The channel 3 and channel 3N duty cycle is set to 25%
The channel 4 duty cycle is set to 12.5%
The Timer pulse is calculated as follows:
  - ChannelxPulse = DutyCycle * (TIM1_Period - 1) / 100

The TIM1 waveform can be displayed using an oscilloscope.

    - Connect the TIM1 pins to an oscilloscope to monitor the different waveforms:
      - TIM1_CH1  pin (PA8)
      - TIM1_CH1N pin (PB13)
      - TIM1_CH2  pin (PA9)
      - TIM1_CH2N pin (PB14)
      - TIM1_CH3  pin (PA10)
      - TIM1_CH3N pin (PB15)
      - TIM1_CH4  pin (PB11)


@par How to use it ? 

In order to make the program work, you must do the following :
 - Open TIM_7PWM_Output.uvprojx from this example folder by Keil MDK5
 - Rebuild all files and load your image into target memory
 - Run the example
