Example description
===================
This example shows how to configure the TIM1 peripheral to generate 6 Steps.
The STM32F10x TIM1 peripheral offers the possibility to program in advance the 
configuration for the next TIM1 outputs behaviour (step) and change the configuration
of all the channels at the same time. This operation is possible when the COM 
(commutation) event is used.
The COM event can be generated by software by setting the COM bit in the TIM1_EGR
register or by hardware (on TRC rising edge).
In this example, a software COM event is generated each 100 ms: using the SysTick 
interrupt.
The TIM1 is configured in Timing Mode, each time a COM event occurs, a new TIM1
configuration will be set in advance.

The break Polarity is used at High level.

The following Table describes the TIM1 Channels states:

              -----------------------------------------------
             | Step1 | Step2 | Step3 | Step4 | Step5 | Step6 |
   ----------------------------------------------------------
  |Channel1  |   1   |   0   |   0   |   0   |   0   |   1   |
   ----------------------------------------------------------
  |Channel1N |   0   |   0   |   1   |   1   |   0   |   0   |
   ----------------------------------------------------------
  |Channel2  |   0   |   0   |   0   |   1   |   1   |   0   |
   ----------------------------------------------------------
  |Channel2N |   1   |   1   |   0   |   0   |   0   |   0   |
   ----------------------------------------------------------
  |Channel3  |   0   |   1   |   1   |   0   |   0   |   0   |
   ----------------------------------------------------------
  |Channel3N |   0   |   0   |   0   |   0   |   1   |   1   |

Hardware environment
====================
This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
boards and can be easily tailored to any other hardware.
There is no need for any modification when switching between these two boards.

- Connect the TIM1 pins to an oscilloscope to monitor the different waveforms:
    - TIM1_CH3  pin (PA.10)
    - TIM1_CH1N pin (PB.13)  
    - TIM1_CH2  pin (PA.09)  
    - TIM1_CH3N pin (PB.15)
    - TIM1_CH1  pin (PA.08)  
    - TIM1_CH2N pin (PB.14)  
  
- Connect the TIM1 break pin TIM1_BKIN pin (PB.12) to the GND. To generate a break
  event, switch this pin level from 0V to 3.3V.  

  
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
  + stm32f10x_systick.c
  
- Link all compiled files and load your image into target memory
- Run the example
