帮我用标准库在两块stm32f103c8t6上写一个can通讯板间交互代码

抱歉，作为AI语言模型，我没有实际硬件编程的能力。但是，我可以给您提供一些概念和代码框架，帮助您开始基于标准库在两块stm32f103c8t6上编写CAN通信板间交互代码。

1. 首先，您需要在两块stm32f103c8t6上配置CAN硬件，并初始化CAN控制器。以下是在单个stm32f103c8t6上对CAN控制器进行配置和初始化的示例代码，供您参考：

#include "stm32f10x.h"

void CAN_Config(void)
{
  GPIO_InitTypeDef GPIO_InitStructure;
  CAN_InitTypeDef CAN_InitStructure;

  // GPIO clock enable
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO | RCC_APB2Periph_GPIOB, ENABLE);

  // Configure CAN RX/TX pins
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOB, &GPIO_InitStructure);

  // CAN clock enable
  RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN1, ENABLE);

  // CAN configuration
  CAN_InitStructure.CAN_Mode = CAN_Mode_Normal;
  CAN_InitStructure.CAN_SJW = CAN_SJW_1tq;
  CAN_InitStructure.CAN_BS1 = CAN_BS1_8tq;
  CAN_InitStructure.CAN_BS2 = CAN_BS2_3tq;
  CAN_InitStructure.CAN_Prescaler = 16;
  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_Init(CAN1, &CAN_InitStructure);
}

2. 在stm32f103c8t6上使用CAN发送消息。以下是一个简单的CAN发送函数，您可以将其用于发送CAN消息到另一个stm32f103c8t6：

void CAN_SendMsg(uint8_t* data, uint8_t len, uint32_t id)
{
    CAN_MessageTypeDef TxMessage;

    TxMessage.IDE = CAN_ID_EXT; // using extended identifier mode
    TxMessage.DLC = len;
    TxMessage.TransmitGlobalTime = DISABLE; // not using time stamp
    TxMessage.StdId = id; // setting the message ID
    memcpy(TxMessage.Data, data, len);

    // send the message
    CAN_Transmit(CAN1, &TxMessage);
}

3. 在stm32f103c8t6上使用CAN接收消息。以下是一个简单的CAN接收函数，用于接收另一个stm32f103c8t6发送的CAN消息：

void CAN_ReceiveMsg(uint8_t* data, uint8_t* len, uint32_t* id)
{
    CAN_MessageTypeDef RxMessage;

    // wait for a new message to arrive
    while(!CAN_MessagePending(CAN1, CAN_FIFO0));

    // receive the message
    CAN_Receive(CAN1, CAN_FIFO0, &RxMessage);

    // copy the received message to the output parameters
    memcpy(data, RxMessage.Data, RxMessage.DLC);
    *len = RxMessage.DLC;
    *id = RxMessage.StdId;
}

4. 最后，您需要编写代码以在两个stm32f103c8t6之间发送和接收CAN消息。以下是一个简单的示例函数，演示如何在两个stm32f103c8t6上发送和接收CAN消息：

void CAN_Interact(void)
{
    uint8_t tx_data[] = {0x01, 0x02, 0x03};
    uint8_t rx_data[8];
    uint8_t rx_len;
    uint32_t rx_id;

    // configure CAN on both devices
    CAN_Config();

    // send a message from device 1 to device 2
    CAN_SendMsg(tx_data, 3, 0x100);

    // receive the message on device 2
    CAN_ReceiveMsg(rx_data, &rx_len, &rx_id);

    // do something with the received message
    // ...

    // send a response message from device 2 back to device 1
    CAN_SendMsg(rx_data, rx_len, rx_id);

    // receive the response message on device 1
    CAN_ReceiveMsg(tx_data, &rx_len, &rx_id);

    // do something with the received response message
    // ...
}

请注意，以上代码仅提供了一个简单的示例，您需要根据您的实际需求进行修改和扩展。
