Example description
===================
This example shows how to configure the TIM1 peripheral to generate 7 PWM signals
with 4 different duty cycles.
TIM1CLK is fixed to 72 MHz, the TIM1 Prescaler is equal to 0 so the TIM1 counter
clock used is 72 MHz.
TIM1 frequency is defined as follow:
TIM1 frequency = TIM1CLK/(TIM1_Period + 1) = 17.57 KHz.
The TIM1 CCR1 register value is equal to 0x7FF, so the TIM1 Channel 1 and TIM1
Channel 1N generate a PWM signal with a frequency equal to 17.57 KHz
and a duty cycle equal to:
TIM1 Channel1 duty cycle = TIM1_CCR1 /( TIM1_Period + 1) = 50%.
The TIM1 CCR2 register value is equal to 0x5FF, so the TIM1 Channel 2 and TIM1
Channel 2N generate a PWM signal with a frequency equal to 17.57 KHz
and a duty cycle equal to:
TIM1 Channel2 duty cycle = TIM1_CCR2 / ( TIM1_Period + 1)= 37.5%.
The TIM1 CCR3 register value is equal to 0x3FF, so the TIM1 Channel 3 and TIM1
Channel 3N generate a PWM signal with a frequency equal to 17.57 KHz
and a duty cycle equal to:
TIM1 Channel3 duty cycle = TIM1_CCR3 / ( TIM1_Period + 1) = 25%.
The TIM1 CCR4 register value is equal to 0x1FF, so the TIM1 Channel 4
generate a PWM signal with a frequency equal to 17.57 KHz
and a duty cycle equal to:
TIM1 Channel4 duty cycle = TIM1_CCR4 / ( TIM1_Period + 1) = 12.5%.
The TIM1 waveform can be displayed using an oscilloscope.

Hardware environment
====================
This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
boards and can be easily tailored to any other hardware.
Connect the TIM1 pins to an oscilloscope to monitor the different waveforms:
- TIM1_CH1 pin (PA.08)
- TIM1_CH1N pin (PB.13)
- TIM1_CH2 pin (PA.09)
- TIM1_CH2N pin (PB.14)
- TIM1_CH3 pin (PA.10)
- TIM1_CH3N pin (PB.15)
- TIM1_CH4 pin (PA.11)
How to use it
=============
In order to make the program work, you must do the following:
- Create a project and setup all your toolchain's start-up files
- Compile the directory content files and required Library files:
+ stm32f10x_lib.c
+ stm32f10x_tim.c
+ stm32f10x_gpio.c
+ stm32f10x_rcc.c
+ stm32f10x_nvic.c
+ stm32f10x_flash.c
- Link all compiled files and load your image into target memory
- Run the example
