环形存储区

發布時間：2025/4/16 编程问答 20 豆豆

生活随笔收集整理的這篇文章主要介紹了环形存储区小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

環形存儲區

概念：當多個不同線程調用同一接口如串口時，會出現干涉情況。增加環形存儲區后，會將不同線程的調用指令放入同一數組中輪詢調用同一接口。

具體內碼如下：

typedef?struct?

????uint16_t?send_cmd[50];??????????//發送指令

????uint16_t?send_para[50];?????????//發送內容?

????uint8_t?send_add_in_number;?????//數組遞增序列號，遞增到50后變為0????

????uint8_t?send_sub_out_number;????//數組遞減序列號，遞增到50后變為0??

????uint8_t?send_times;?????????????//表示數組里，待發送的數量??

}modbus_huiling_t;

extern?modbus_huiling_t?modbus_huiling;?

//將調用指令增加到環形數組?

int?add_modbus_cmd(uint8_t?huiling_cmd,?uint16_t?para_time)?

{

????modbus_huiling.send_times++;?

????modbus_huiling.send_cmd[modbus_huiling.send_add_in_number]?=?huiling_cmd;?

????modbus_huiling.send_para[modbus_huiling.send_add_in_number]?=?para_time;??

????log_d("send_times?=?%d?\r\n",?modbus_huiling.send_times);??

????log_d("send_add_in_number?=?%d\r\n",?modbus_huiling.send_add_in_number);?

????if(modbus_huiling.send_add_in_number?>=?49)?????

????????modbus_huiling.send_add_in_number?=?0;

????else?

????????modbus_huiling.send_add_in_number++;

????return?0;?

//環形數組遞減，串口完成后調用此接口

static?int?sub_modbus_cmd(void)???

{

????modbus_huiling.send_times?--;?

????if(modbus_huiling.send_sub_out_number?>=49)??

????????modbus_huiling.send_sub_out_number?=?0;

????else

????????modbus_huiling.send_sub_out_number?++;?

}
