TIM1CLK is fixed to 2 MHz, the TIM1 Prescaler is equal to 0 so the TIM1 counter clock used is 2 MHz. (By default, fTimer1= fMaster/8 ) TIM1 frequency is defined as follows: TIM1 frequency = TIM1 counter clock / (TIM1_Period + 1) = 488.28 Hz. The TIM1 CCR1 register value is equal to 0x7FF, so the TIM1 Channel 1 and TIM1 Channel 1N generate a PWM signal with a frequency equal to 488.28Hz and a duty cycle equal to: TIM1 Channel1 duty cycle = TIM1_CCR1 /( TIM1_Period + 1) = 50%. The TIM1 CCR2 register value is equal to 0x5FF, so the TIM1 Channel 2 and TIM1 Channel 2N generate a PWM signal with a frequency equal to 488.28 Hz and a duty cycle equal to: TIM1 Channel2 duty cycle = TIM1_CCR2 / ( TIM1_Period + 1)= 37.5%. The TIM1 CCR3 register value is equal to 0x3FF, so the TIM1 Channel 3 and TIM1 Channel 3N generate a PWM signal with a frequency equal to 488.28 Hz and a duty cycle equal to: TIM1 Channel3 duty cycle = TIM1_CCR3 / ( TIM1_Period + 1) = 25%. The TIM1 CCR4 register value is equal to 0x1FF, so the TIM1 Channel 4 generate a PWM signal with a frequency equal to 488.28 Hz and a duty cycle equal to: TIM1 Channel4 duty cycle = TIM1_CCR4 / ( TIM1_Period + 1) = 12.5%. The TIM1 waveform can be displayed using an oscilloscope. @par Directory contents - TIM1\TIM1_7PWM_Output\main.c Main file containing the "main" function - TIM1\TIM1_7PWM_Output\stm8s_conf.h Library Configuration file - TIM1\TIM1_7PWM_Output\stm8s_it.c Interrupt routines source - TIM1\TIM1_7PWM_Output\stm8s_it.h Interrupt routines declaration @par Hardware and Software environment - This example runs on STM8S and STM8A High density, Medium density and Low density devices. - This example has been tested with STMicroelectronics STM8/128-EVAL evaluation board and can be easily tailored to any other development board. - Connect TIM1 pins to an oscilloscope as follows: - TIM1_CH1 pin (PC.1) - TIM1_CH1N pin (PH.7) - TIM1_CH2 pin (PC.2) - TIM1_CH2N pin (PH.6) - TIM1_CH3 pin (PC.3) - TIM1_CH3N pin (PH.5) - TIM1_CH4 pin (PC.4) @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\Template - Open your preferred toolchain - Rebuild all files and load your image into target memory - Run the example - Connect the TIM1 pins to an oscilloscope @note - High-Density STM8A devices are the STM8AF52xx STM8AF6269/8x/Ax, STM8AF51xx, and STM8AF6169/7x/8x/9x/Ax microcontrollers where the Flash memory density ranges between 32 to 128 Kbytes - Medium-Density STM8A devices are the STM8AF622x/4x, STM8AF6266/68, STM8AF612x/4x, and STM8AF6166/68 microcontrollers where the Flash memory density ranges between 8 to 32 Kbytes - High-Density STM8S devices are the STM8S207xx, STM8S007 and STM8S208xx microcontrollers where the Flash memory density ranges between 32 to 128 Kbytes. - Medium-Density STM8S devices are the STM8S105x and STM8S005 microcontrollers where the Flash memory density ranges between 16 to 32-Kbytes. - Low-Density STM8S devices are the STM8S103xx, STM8S003 and STM8S903xx microcontrollers where the Flash density is 8 Kbytes. *
