+@par Example Description 
+
+This example shows how to use the TIM peripheral to generate a One pulse Mode 
+after a Rising edge of an external signal is received in Timer Input pin.
+
+TIM2CLK = SystemCoreClock, we want to get TIM2 counter clock at 24 MHz:
+  - Prescaler = (TIM2CLK / TIM2 counter clock) - 1
+SystemCoreClock is set to 72 MHz for Low-density, Medium-density, High-density
+and Connectivity line devices and to 24 MHz for Low-Density Value line,
+Medium-Density Value line and High-Density devices.
+
+The Autoreload value is 65535 (TIM4->ARR), so the maximum frequency value to 
+trigger the TIM4 input is 24000000/65535 = 300 Hz.
+
+The TIM4 is configured as follows: 
+The One Pulse mode is used, the external signal is connected to TIM4 CH2 pin (PB.07), 
+the rising edge is used as active edge, the One Pulse signal is output 
+on TIM4_CH1 (PB.06).
+
+The TIM_Pulse defines the delay value, the delay value is fixed to:
+delay =  CCR1/TIM4 counter clock = 16383 / 24000000 = 682.6 us. 
+The (TIM_Period - TIM_Pulse) defines the One Pulse value, the pulse value is fixed to:
+One Pulse value = (TIM_Period - TIM_Pulse)/TIM4 counter clock 
+                = (65535 - 16383) / 24000000 = 2.048 ms.

+@par Hardware and Software environment 
+
+  - This example runs on STM32F10x Connectivity line, High-Density, High-Density 
+    Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density 
+    and Low-Density Value line Devices.
+  
+  - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
+    Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL (Connectivity line), 
+    STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density) 
+    evaluation boards and can be easily tailored to any other supported device 
+    and development board.
+
+  - STM32100B-EVAL, STM3210E-EVAL, STM3210B-EVAL, STM32100E-EVAL and STM3210C-EVAL  Set-up 
+   - Connect the external signal to the TIM4_CH2 pin (PB.07)
+   - Connect the TIM4_CH1 (PB.06) pin to an oscilloscope to monitor the waveform.   
+  
+@par How to use it ? 
+
+In order to make the program work, you must do the following :
+ - Copy all source files from this example folder to the template folder under
+   Project\STM32F10x_StdPeriph_Template
+ - Open your preferred toolchain 
+ - Rebuild all files and load your image into target memory
+ - Run the example 
+
+@note
+ - Low-density Value line devices are STM32F100xx microcontrollers where the 
+   Flash memory density ranges between 16 and 32 Kbytes.
+ - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
+ - Medium-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 64 and 128 Kbytes.  
+ - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
+ - High-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes.
+ - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes.
+ - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 512 and 1024 Kbytes.
+ - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
