+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
