C语言实现的串口query 缓存 8 bit一存，一帧一取，欢迎大家使用。
.c文件

/* *先入先出队列 */uint8_t receive_buff[QUEUE_SIZE] = { 0 };uint8_t front = 0;uint8_t rear = 0;bool QueryPush(uint8_t dat){    if (((front + 1) % QUEUE_SIZE) != rear)  //队列没满    {        receive_buff[front++] = dat;        front %= QUEUE_SIZE;        return TRUE;    }    else        return FALSE;}bool QueryPop(uint8_t *dat){    if (front != rear)       //队列不为空    {        *dat = receive_buff[rear++];        rear %= QUEUE_SIZE;        return TRUE;    }    return FALSE;}/*Modbus一帧数据出栈*/bool PopFreame(uint8_t *buffer){    uint8_t data = 0;    uint8_t count = 0;    while ((count < FREAME_SIZE) && QueryPop(&data))    {        buffer[count++] = data;    }    if (count != FREAME_SIZE)              return FALSE;    else    {        count = 0;        return TRUE;    }}

.h文件

#ifndef __QUEUE_H_#define __QUEUE_H_#include "stm8s.h"#define QUEUE_SIZE 32           //需要定义的空间大小为帧大小*帧数，例如帧大小为8B共4帧则为32bool QueryPush(uint8_t dat);bool QueryPop(uint8_t *dat);bool PopFreame(uint8_t *buffer);#endif
