@par Example Description

This example shows how to configure the TIM peripheral to generate four different
signals with four different delays.

The TIM3CLK frequency is set to SystemCoreClock / 2 (Hz), and the objective is
to get TIM3 counter clock at 1 KHz so the Prescaler is computed as following:
- Prescaler = (TIM3CLK / TIM3 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 Value line devices.

The TIM3 CCR1 register value is equal to 1000:
TIM3_CH1 delay = CCR1_Val/TIM3 counter clock = 1000 ms
so the TIM3 Channel 1 generates a signal with a delay equal to 1000 ms.

The TIM3 CCR2 register value is equal to 500:
TIM3_CH2 delay = CCR2_Val/TIM3 counter clock = 500 ms
so the TIM3 Channel 2 generates a signal with a delay equal to 500 ms.

The TIM3 CCR3 register value is equal to 250:
TIM3_CH3 delay = CCR3_Val/TIM3 counter clock = 250 ms
so the TIM3 Channel 3 generates a signal with a delay equal to 250 ms.

The TIM3 CCR4 register value is equal to 125:
TIM3_CH4 delay = CCR4_Val/TIM3 counter clock = 125 ms
so the TIM3 Channel 4 generates a signal with a delay equal to 125 ms.

The delay correspond to the time difference between PC.06 and
TIM3_CHx signal rising edges in case of STM32100E-EVAL, STM32100B-EVAL, STM3210E-EVAL
and STM3210B-EVAL

The delay correspond to the time difference between PD.07 and
TIM3_CHx signal rising edges in case of STM3210C-EVAL

@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.


- STM3210C-EVAL Set-up
- Connect the TIM3 pins(TIM3 full remapped pins) to an oscilloscope to
monitor the different waveforms:
- PD.07
- PC.06 (TIM3_CH1)
- PC.07 (TIM3_CH2)
- PC.08 (TIM3_CH3)
- PC.09 (TIM3_CH4)

- STM32100E-EVAL, STM32100B-EVAL, STM3210E-EVAL and STM3210B-EVAL Set-up
- Connect the following pins to an oscilloscope to monitor the different
waveforms:
- PC.06
- PA.06 (TIM3_CH1)
- PA.07 (TIM3_CH2)
- PB.00 (TIM3_CH3)
- PB.01 (TIM3_CH4)

@par How to use it ?

In order to make the program work, you must do the following :
