主函数中调用serial_init();串口初始化
serial_recv();串口接收数据
用vscode进行模拟时，程序运行到这行代码就出现异常
status = serial_handler->frame_recv(serial_handler);

上面这个库文件是厂家串口函数定义结构体和枚举的头文件；
void *serial_recv(void)
{
serial_status_t status = SERIAL_SUCCESS;
status = serial_handler->frame_recv(serial_handler);
if (status == SERIAL_SUCCESS)
{
printf("recv len = %d,recv=", serial_handler->serial_frame_length);
for (int i = 0; i < serial_handler->serial_frame_length; i++)
{
printf("%c", serial_handler->serial_frame_buff[i]); //打印接收到的数据
}
//received_data = (char *)serial_handler->serial_frame_buff;
}
}
问了一下厂家说在这个recv函数中写个函数显示上去，可是这个函数都运行报错，这个代码要怎么修改呀
