+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.

+
+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
