-Example description
-===================
-
-This example shows how to synchronize TIM peripherals in cascade mode with an
-external trigger.
-In this example three timers are used:
-
-1/TIM2 is configured as Master Timer:
- - Toggle Mode is used
- - The TIM2 Enable event is used as Trigger Output
-
-2/TIM2 is configured as Slave Timer for an external Trigger connected to TIM2 TI2 pin
-(TIM2 CH2 configured as input pin):
- - The TIM2 TI2FP2 is used as Trigger Input
- - Rising edge is used to enable and stop the TIM2: Gated Mode.
-
-3/TIM3 is slave for TIM2 and Master for TIM4,
- - Toggle Mode is used
- - The ITR1(TIM2) is used as input trigger
- - Gated mode is used, so start and stop of slave counter are controlled by the Master
- trigger output signal(TIM2 enable event).
- - The TIM3 enable event is used as Trigger Output.
-
-4/TIM4 is slave for TIM3,
- - Toggle Mode is used
- - The ITR2(TIM3) is used as input trigger
- - Gated mode is used, so start and stop of slave counter are controlled by the Master
-trigger output signal(TIM3 enable event).
-
-The TIMxCLK is fixed to 72 MHZ, the Prescaler is equal to 2 so the TIMx clock counter
-is equal to 24 MHz.
-The Three Timers are running at:
-TIMx frequency = TIMx clock counter/ 2*(TIMx_Period + 1) = 162.1 KHz.
-
-The starts and stops of the TIM2 counter are controlled by the external trigger.
-The TIM3 starts and stops are controlled by the TIM2, and the TIM4 starts and stops
-are controlled by the TIM3.

-Directory contents
-==================
-stm32f10x_conf.h Library Configuration file
-stm32f10x_it.c Interrupt handlers
-stm32f10x_it.h Interrupt handlers header file
-main.c Main program
-
-
-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 an external trigger, with a frequency <= 40KHz, to the TIM2 CH2 pin (PA.01).
- In this example the frequency is equal to 5 KHz.
-
-- Connect the:
- - TIM2 CH1 (PA.00)
- - TIM3 CH1 (PA.06)
- - TIM4 CH1 (PB.06)
- pins to an oscilloscope to monitor the different waveforms.
-
-
-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
- + stm32ff10x_flash.c
-
-- Link all compiled files and load your image into target memory
-- Run the example
