N32G032单霍尔编码器测速问题

只看该作者 · 2023-4-5 23:20

这个是参考STM32F103单片机配置的一个N32G032的单霍尔测速程序，为什么程序没反应？
有弄过这个的大佬吗？求帮忙看一下是什么问题

/*定时器8-CH1 输入的编码信号*/
void EncodeTimeInit(void)
{
GPIO_InitType GPIO_InitStructure;
NVIC_InitType NVIC_InitStructure;

/*GPIOB clock enable */
RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_GPIOB | RCC_APB2_PERIPH_AFIO,ENABLE);

/*PB12 - Encode Signal Input port1*/
GPIO_InitStructure.Pin = GPIO_PIN_12;

}

}
else
{

}
}

}

GPIO没有配置复用？

配置了还是不行

RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_TIM8, ENABLE);
/*GPIOB clock enable */
RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_GPIOB | RCC_APB2_PERIPH_AFIO,ENABLE);

/*PB12 - Encode Signal Input port1*/
GPIO_InitStructure.Pin = GPIO_PIN_12;
GPIO_InitStructure.GPIO_Mode =GPIO_MODE_INPUT;
GPIO_InitStructure.GPIO_Speed =GPIO_SPEED_HIGH;
GPIO_InitStructure.GPIO_Alternate = GPIO_AF5_TIM8;
GPIO_InitPeripheral(GPIOB, &GPIO_InitStructure);
