AS A RESULT, STMICROELECTRONICS SHALL NOT BE HELD LIABLE FOR ANY * DIRECT, INDIRECT OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY CLAIMS ARISING * FROM THE CONTENT OF SUCH FIRMWARE AND/OR THE USE MADE BY CUSTOMERS OF THE * CODING INFORMATION CONTAINED HEREIN IN CONNECTION WITH THEIR PRODUCTS. ****************************************************************************** @endverbatim @par Example Description This example shows how to use the TIM peripheral to measure the frequency of an external signal. The TIMxCLK frequency is set to SystemCoreClock (Hz), the Prescaler is 0 so the TIM3 counter clock is SystemCoreClock (Hz). SystemCoreClock is set to 72 MHz for Low-density, Medium-density, High-density and Connectivity line devices. For Low-Density Value line and Medium-Density Value line devices, SystemCoreClock is set to 24 MHz. TIM3 is configured in Input Capture Mode: the external signal is connected to TIM3 Channel2 used as input pin. To measure the frequency we use the TIM3 CC2 interrupt request, so In the TIM3_IRQHandler routine, the frequency of the external signal is computed. The "TIM3Freq" variable contains the external signal frequency: TIM3Freq = TIM3 counter clock / Capture in Hz, where the Capture is the difference between two consecutive TIM3 captures. For Low-density, Medium-density, High-density and Connectivity line devices, the minimum frequency value to measure is 1100 Hz. For Low-Density Value line, Medium-Density and High-Density Value line devices, the minimum frequency value to measure is 366 Hz. @par Directory contents - TIM/InputCapture/stm32f10x_conf.h Library Configuration file - TIM/InputCapture/stm32f10x_it.c Interrupt handlers - TIM/InputCapture/stm32f10x_it.h Interrupt handlers header file - TIM/InputCapture/main.c Main program - TIM/InputCapture/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. - STM32100E-EVAL, STM32100B-EVAL, STM3210C-EVAL, STM3210E-EVAL and STM3210B-EVAL Set-up - Connect the external signal to measure to the TIM3 CH2 pin (PA.07). @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 *** and 128 Kbytes. - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers where the Flash memory density ranges between *** 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. *
