+Example description
+===================
+This example shows how to configure the TIM2 peripheral to generate four different
+signals with four different frequencies.
+
+The TIM2CLK frequency is set to 36 MHz, the Prescaler is set to 2, and used in
+Output Compare Toggle Mode.
+
+TIM2 counter clock = TIMxCLK / (Prescaler +1) = 12 MHz
+
+The TIM2 CCR1 register value is equal to 32768:
+CC1 update rate = TIM2 counter clock / CCR1_Val = 366.2 Hz,
+so the TIM2 Channel 1 generates a periodic signal with a frequency equal to 183.1 Hz.
+
+The TIM2 CCR2 register is equal to 16384:
+CC2 update rate = TIM2 counter clock / CCR2_Val = 732.4 Hz
+so the TIM2 channel 2 generates a periodic signal with a frequency equal to 366.3 Hz.
+
+The TIM2 CCR3 register is equal to 8192:
+CC3 update rate = TIM2 counter clock / CCR3_Val = 1464.8 Hz
+so the TIM2 channel 3 generates a periodic signal with a frequency equal to 732.4 Hz.
+
+The TIM2 CCR4 register is equal to 4096:
+CC4 update rate = TIM2 counter clock / CCR4_Val = 2929.6 Hz
+so the TIM2 channel 4 generates a periodic signal with a frequency equal to 1464.8 Hz.

+
+
+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:
+- PA.00 (TIM2_CH1)
+- PA.01 (TIM2_CH2)
+- PA.02 (TIM2_CH3)
+- PA.03 (TIM2_CH4)
+pins to an oscilloscope to monitor the different waveform.
+
+
+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
