The CK_TIM frequency is set to 60 MHz, the TIM is running at 30 MHz, the Pulse period is equal to 546 µs and the PWM Period duration is fixed to 2.18 ms. The TIM0 provide on its OC2 pin a PWM signal with a frequency equal to 458 Hz and a duty cycle equal to 25%. The PWM waveform can be displayed using an oscilloscope. Directory contents ================== 75x_conf.h Library Configuration file 75x_it.c Interrupt handlers main.c Main program Hardware environment ==================== Connect TIM0_OC2 pin (P1.00) to an oscilloscope. 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 : + 75x_lib.c + 75x_tim.c + 75x_gpio.c + 75x_mrcc.c + 75x_cfg.c - Link all compiled files and load your image into either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2006 STMicroelectronics *****END OF FILE******
