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 Directory contents - TIM/OCActive/stm32f10x_conf.h Library Configuration file - TIM/OCActive/stm32f10x_it.c Interrupt handlers - TIM/OCActive/stm32f10x_it.h Interrupt handlers header file - TIM/OCActive/main.c Main program - TIM/OCActive/system_stm32f10x.c STM32F10x system source file @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 : - 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. *
