The TIM2CLK frequency is set to 36 MHz, the Prescaler is set to 0x2, and used in Output Compare Toggle Mode. TIM2 counter clock = TIMxCLK / (Prescaler +1) = 12 MHz The TIM2 CC1 register value is equal to 0x8000: 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 CC2 register is equal to 0x4000: 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 CC3 register is equal to 0x2000: CC3 update rate = TIM2 counter clock / CCR3_Val = 14***.8 Hz so the TIM2 channel 3 generates a periodic signal with a frequency equal to 732.4 Hz. The TIM2 CC4 register is equal to 0x1000: 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 14***.8 Hz. Directory contents ================== stm32F10x_conf.h Library Configuration file stm32F10x_it.c Interrupt handlers stm32F10x_it.h Interrupt handlers header file main.c Main program Hardware environment ==================== Connect an oscilloscope on: - PA.00 (TIM2_CH1) - PA.01 (TIM2_CH2) - PA.02 (TIM2_CH3) - PA.03 (TIM2_CH4) to show the four different signals. 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 either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2007 STMicroelectronics *****END OF FILE******
