使用DSP芯片的CAN通信代码

由于涉及到具体的DSP芯片型号和开发环境，所以无法提供具体的代码。以下是一些通用的CAN通信代码片段，供参考：

1. 初始化CAN

// 定义CAN参数
CAN_Params params;
CAN_Params_init(&params);
params.bitRate = 500000;
params.txBuf = txBuf;
params.rxBuf = rxBuf;
params.txBufLen = TX_BUF_LEN;
params.rxBufLen = RX_BUF_LEN;

// 打开CAN模块
CAN_Handle handle = CAN_open(CAN_CONFIG_0, &params);

// 配置过滤器
CAN_FilterConfig filterCfg;
CAN_FilterConfig_init(&filterCfg);
filterCfg.action = CAN_FILTER_SET;
filterCfg.format = CAN_FILTER_FORMAT_STANDARD;
filterCfg.mask = 0x7FF;
filterCfg.filterIdHigh = 0x100; // 过滤器ID
filterCfg.filterIdLow = 0x0;
filterCfg.filterMaskIdHigh = 0x0;
filterCfg.filterMaskIdLow = 0x0;
CAN_control(handle, CAN_CMD_FILTER_CONFIG, &filterCfg);

// 启动CAN模块
CAN_start(handle);

2. 发送CAN数据

CAN_Frame frame;
CAN_Frame_setStdId(&frame, 0x100); // 发送帧ID
frame.dataLen = 8; // 数据长度
frame.data[0] = 0x01; // 数据内容
frame.data[1] = 0x02;
frame.data[2] = 0x03;
frame.data[3] = 0x04;
frame.data[4] = 0x05;
frame.data[5] = 0x06;
frame.data[6] = 0x07;
frame.data[7] = 0x08;
CAN_write(handle, &frame, 0);

3. 接收CAN数据

CAN_Frame frame;
uint32_t status = CAN_read(handle, &frame, 0);
if (status != CAN_STATUS_SUCCESS) {
    // 处理接收错误
} else {
    // 处理接收数据
}
