TIM1CLK is fixed to 72 MHz, the TIM1 Prescaler is equal to 0x0 so the TIM1 counter clock used is 72 MHz. TIM1 frequency is defined as follow: TIM1 frequency = TIM1 counter clock / (TIM1_Period + 1) = 1.0*** KHz. The Three Duty cycles are computed as the following description: TIM1 Channel1 duty cycle = TIM1_CCR1 / (TIM1_Period + 1) = 50% TIM1 Channel1N duty cycle = (TIM1_Period - TIM1_CCR1) / (TIM1_Period + 1) = 50% TIM1 Channel2 duty cycle = TIM1_CCR2 / (TIM1_Period + 1) = 25% TIM1 Channel2N duty cycle = (TIM1_Period - TIM1_CCR1) / (TIM1_Period + 1) = 75% TIM1 Channel3 duty cycle = TIM1_CCR3 / TIM1_Period = 12.5% TIM1 Channel3N duty cycle = (TIM1_Period - TIM1_CCR3) / (TIM1_Period + 1) = 87.5% A dead time of 1.62 us is inserted between the different complementary signals, and the Lock level 1 is selected. The break Polarity is used at High level. The TIM1 waveform can be displayed using an oscilloscope. 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 the TIM1 pins to an oscilloscope: - TIM1_CH1 pin (PA.08) - TIM1_CH1N pin (PB.13) - TIM1_CH2 pin (PA.09) - TIM1_CH2N pin (PB.14) - TIM1_CH3 pin (PA.10) - TIM1_CH3N pin (PB.15) Connect the TIM1 break pin TIM1_BKIN pin (PB.12) to the GND. To generate a break event, switch this pin level from 0V to 3.3V. 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_tim1.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******
