gd32f103rct can

GD32F103RCT6是一款基于ARM Cortex-M3内核的微控制器，它具有丰富的外设和功能。其中包括CAN通信功能。下面是使用HAL库在GD32F103RCT6上进行CAN通信的示例代码：

#include "gd32f10x.h"
#include "gd32f10x_can.h"

void CAN_Config(void)
{
    CAN_InitPara CAN_InitStructure;
    CAN_FilterInitPara CAN_FilterInitStructure;

    /* 使能CAN时钟 */
    RCC_APB1PeriphClock_Enable(RCC_APB1PERIPH_CAN0, ENABLE);

    /* 配置CAN引脚 */
    GPIO_InitPara GPIO_InitStructure;
    RCC_APB2PeriphClock_Enable(RCC_APB2PERIPH_GPIOB, ENABLE);
    GPIO_InitStructure.GPIO_Pin = GPIO_PIN_8;
    GPIO_InitStructure.GPIO_Mode = GPIO_MODE_IPU;
    GPIO_InitStructure.GPIO_Speed = GPIO_SPEED_50MHZ;
    GPIO_Init(GPIOB, &GPIO_InitStructure);

    /* CAN单元初始化 */
    CAN_DeInit(CAN0);
    CAN_StructInit(&CAN_InitStructure);
    CAN_InitStructure.CAN_TTCM = DISABLE;
    CAN_InitStructure.CAN_ABOM = DISABLE;
    CAN_InitStructure.CAN_AWUM = DISABLE;
    CAN_InitStructure.CAN_NART = DISABLE;
    CAN_InitStructure.CAN_RFLM = DISABLE;
    CAN_InitStructure.CAN_TXFP = DISABLE;
    CAN_InitStructure.CAN_Mode = CAN_MODE_NORMAL;
    CAN_InitStructure.CAN_SJW = CAN_SJW_1TQ;
    CAN_InitStructure.CAN_BS1 = CAN_BS1_9TQ;
    CAN_InitStructure.CAN_BS2 = CAN_BS2_8TQ;
    CAN_InitStructure.CAN_Prescaler = 6;
    CAN_Init(CAN0, &CAN_InitStructure);

    /* CAN过滤器初始化 */
    CAN_FilterInitStructure.CAN_FilterNumber = 0;
    CAN_FilterInitStructure.CAN_FilterMode = CAN_FILTERMODE_MASK;
    CAN_FilterInitStructure.CAN_FilterScale = CAN_FILTERSCALE_32BIT;
    CAN_FilterInitStructure.CAN_FilterMaskIdHigh = 0x0000;
    CAN_FilterInitStructure.CAN_FilterMaskIdLow = 0x0000;
    CAN_FilterInitStructure.CAN_FilterIdHigh = 0x0000;
    CAN_FilterInitStructure.CAN_FilterIdLow = 0x0000;
    CAN_FilterInitStructure.CAN_FilterFIFOAssignment = CAN_FIFO0;
    CAN_FilterInitStructure.CAN_FilterActivation = ENABLE;
    CAN_FilterInit(&CAN_FilterInitStructure);

    /* 使能CAN接收中断 */
    CAN_INTConfig(CAN0, CAN_INT_RFNE0, ENABLE);
    NVIC_EnableIRQ(CAN0_RX0_IRQn);
}

void CAN0_RX0_IRQHandler(void)
{
    if (CAN_GetITStatus(CAN0, CAN_INT_RFNE0) != RESET)
    {
        CAN_Receive(CAN0, CAN_FIFO0, &RxMessage);
        // 处理接收到的数据
    }
}

int main(void)
{
    CAN_Config();

    while (1)
    {
        // 发送CAN数据
        CAN_Transmit(CAN0, &TxMessage);
    }
}

以上代码是一个简单的CAN通信示例，其中包括了CAN的初始化、过滤器配置、中断处理和数据发送。你可以根据自己的需求进行修改和扩展。
