linux, 函数, 串口调试, UART, unsigned

代码调试完毕，没有问题，结构清晰。

下面是头文件的代码，c文件代码请下载附件。

/*

*/

struct T_UART_DEVICE

{

char *uart_name;

int (*ptr_fun)(unsigned char *buf,unsigned int len);

unsigned char uart_num;

unsigned char databits;

unsigned char parity;

unsigned char stopbits;

unsigned int  baudrate;

};

extern struct T_UART_DEVICE uart_device;

/*

* 根据串口的名称，确定在uart_dev[]中的编号，比如/dev/ttyO0对应0，/dev/ttyO1对应1

* 返回值是串口的编号

*/

int open_uart_dev(char *uart_name);

int set_uart_opt(char *uart_name, int speed, int bits, char event, int stop);

int read_uart_data(char *uart_name, char *rcv_buf, int time_out_ms, int buf_len);

int send_uart_data(char *uart_name, char *send_buf, int buf_len);

int close_uart_dev(char *uart_name);

/*

* 创建串口线程

* uart_recvbuf_and_process是串口线程中的处理函数，参数为ptr_uart_device

* 处理函数必须是int ptr_fun (unsigned char *buf,unsigned int len);类型的函数

*/

int create_uart_pthread(struct T_UART_DEVICE *ptr_uart_device);

void *uart_recvbuf_and_process(void * ptr_uart_device);
