In this example two timers are used: - TIM0 is configured to generate a One Pulse in PWM Mode with a delay fixed to 2.18 ms and a pulse length fixed to 6.55 ms. The External pulse is received on TIM0_TI1 pin. - TIM1 is configured in Output Compare Toggle Mode to generate a signal used as an external input signal for the TIM0 timer. The Timer clock(CK_TIM) is set to 30 MHz. The two timers waveforms 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_TI1 pin (P0.01) to TIM1_OC1 pin (P0.28). - Connect the two timers pins to an oscilloscope: - TIM0_OC1 pin (P0.00) - TIM1_OC1 pin (P0.28) 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_mrcc.c + 75x_gpio.c - Link all compiled files and load your image into either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2006 STMicroelectronics *****END OF FILE******
