-Example description
-===================
-
-This example shows how to synchronize TIM peripherals in cascade mode.
-In this example three timers are used:
-
-Timers synchronisation in cascade mode:
-1/TIM2 is configured as Master Timer:
- - PWM Mode is used
- - The TIM2 Update event is used as Trigger Output
-
-2/TIM3 is slave for TIM2 and Master for TIM4,
- - PWM 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 update event).
- - The TIM3 Update event is used as Trigger Output.
-
-3/TIM4 is slave for TIM3,
- - PWM 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 update event).
-
-The TIMxCLK is fixed to 72 MHz, the TIM2 counter clock is 72 MHz.
-The Master Timer TIM2 is running at TIM2 frequency :
-TIM2 frequency = (TIM2 counter clock)/ (TIM2 period + 1) = 281.250 KHz
-and the duty cycle = TIM2_CCR1/(TIM2_ARR + 1) = 25%.
-
-The TIM3 is running:
- - At (TIM2 frequency)/ (TIM3 period + 1) = 70.312 KHz and a duty cycle equal
-to TIM3_CCR1/(TIM3_ARR + 1) = 25%
-
-The TIM4 is running:
- - At (TIM3 frequency)/ (TIM4 period + 1) = 17.578 Hz and a duty cycle equal
-to TIM4_CCR1/(TIM4_ARR + 1) = 25%

-==================
-stm32f10x_conf.h Library Configuration file
-stm32f10x_it.c Interrupt handlers
-stm32f10x_it.h Interrupt handlers header file

-
-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
-- 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
- + stm32f10x_flash.c
-
-- Link all compiled files and load your image into target memory
-- Run the example
