Posted on May 06, 2015 at 13:00I want to have a sample of system clock at MCO pin of STM32F107RC micro controller.
I use dspin firmware library for driving stepper motor.
The on board crystal is 8MHz and system clock set to be 72MHz.
I add this code to ''dspin.c'':
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOA, &GPIO_InitStructure);
and I add the below line code in ''SetSysClockTo72()'' function at ''system_stm32f10x.c'' file.
RCC->CFGR &= (uint32_t)0xF6FFFFFF; //HSE clock selected as MCO source
But I don't have no clock output on this pin.
please guide me
thanks
