请大神帮忙看看图片中peli_transmit_message的值为何不能成功赋给CAN1_PELI呢
感激不尽

我的CAN 配置函数如下

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_FLOATING;
GPIO_Init(GPIOA, &GPIO_InitStructure);

//CAN TX PA12
GPIO_InitStructure.GPIO_Pin  = GPIO_Pin_12;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

GPIO_Init(GPIOA, &GPIO_InitStructure);

GPIO_PinAFConfig(GPIOA, GPIO_PinSource11, GPIO_AF_4);

NVIC_InitStructure.NVIC_IRQChannel = CAN_IRQn;
