详细写出基于国标27930的stm32f105 can通讯程序 使用标准库

基于国标27930的STM32F105 CAN通讯程序使用标准库的实现步骤如下：

1. 配置CAN硬件参数：首先需要配置CAN硬件的参数，包括波特率、工作模式和过滤器等。可以通过STM32的寄存器来配置CAN硬件参数。

2. 初始化CAN口：在CAN硬件参数配置完成后，需要通过CAN库函数来初始化CAN口，包括设置CAN的时序、初始化CAN中断、设置CAN接收和发送缓冲区等。

3. 发送CAN数据：使用CAN库函数可以轻松地实现CAN数据的发送，只需要将数据写入CAN发送缓冲区，并指定发送的ID即可。

4. 接收CAN数据：使用CAN库函数可以轻松地实现CAN数据的接收，只需要在CAN中断服务函数中读取CAN接收缓冲区中的数据即可。

以下是基于国标27930的STM32F105 CAN通讯程序使用标准库的代码示例：

#include "stm32f10x_can.h"

    GPIO_Init(GPIOA, &GPIO_InitStructure);

    CAN_FilterInitStructure.CAN_FilterFIFOAssignment = CAN_Filter_FIFO0;
    CAN_FilterInitStructure.CAN_FilterActivation = ENABLE;
    CAN_FilterInit(&CAN_FilterInitStructure);
}

/* CAN数据发送 */
void CAN_SendData(uint32_t id, uint8_t* data, uint8_t length)
{
    CanTxMsg TxMessage;

    /* 填充CAN发送数据 */
    TxMessage.StdId = id;
    TxMessage.ExtId = 0x00;
    TxMessage.RTR = CAN_RTR_DATA;
    TxMessage.IDE = CAN_ID_STD;
    TxMessage.DLC = length;
    for(uint8_t i = 0; i < length; i++)
    {
        TxMessage.Data[i] = data[i];
    }

    /* 发送CAN数据 */
    while(CAN_Transmit(CAN1, &TxMessage) != CAN_TxStatus_Ok);
}

/* CAN数据接收 */
void CAN_ReceiveData(void)
{
    CanRxMsg RxMessage;

    /* 读取CAN接收数据 */
    if(CAN_MessagePending(CAN1, CAN_FIFO0) != 0)
    {
        CAN_Receive(CAN1, CAN_FIFO0, &RxMessage);
        /* 处理接收到的CAN数据 */
    }
}

int main(void)
{
    /* CAN硬件参数配置 */
    CAN_Configuration();

    /* 发送CAN数据 */
    uint8_t data[] = {0x01, 0x02, 0x03};
    CAN_SendData(0x123, data, 3);

    while(1)
    {
        /* 接收CAN数据 */
        CAN_ReceiveData();
    }
}

以上代码仅供参考，具体实现还需要根据实际需求进行调整和完善。
