wow-type文件说明

• 项目地址：https://gitee.com/wow-iot/wow-iot7
• 本文件的的功能主要用于处理数据类型的转换，包含字符串、数组、BCD码；
• 由于涉及的类型较多，仅以uint64_t类型进行描述说明；

指针强制类型转换

#define p2u64(x)     ((uint64_t)(size_t)(x))
#define p2s64(x)     ((sint64_t)(size_t)(x))

字符串转数据类型

/*brief    二进制字符串转int64*/
int S2toU64(const char* pcStr,uint64_t* pu64Data);
/*brief    十进制字符串转int64*/
int S10toU64(const char* pcStr,uint64_t* pu64Data);
/*brief    十六进制字符串转int64 */
int S16toU64(const char* pcStr,uint64_t* pu64Data);

具体实现如下：

二进制实现

  uint64_t _S2toU64(const char* pcStr)
 {
	while (isspace(*pcStr)) pcStr++;

	int sign = 0;
	if (*pcStr == '-') {
		sign = 1;
		pcStr++;
	}else if(*pcStr == '+'){
		pcStr++;
	} 

	if (pcStr[0] == '0' && (pcStr[1] == 'b' || pcStr[1] == 'B')){
		 pcStr += 2;
	}

	while ((*pcStr) == '0') pcStr++;

	uint32_t val = 0;
	while (*pcStr){
		char ch = *pcStr;
		CHECK_RET_BREAK(isdigit2(ch));

		val = (val << 1) + (ch - '0');
		pcStr++;
	}


	return (sign)?(~val + 1):val;
 }

十进制进制实现

 uint64_t _S10toU64(const char* pcStr)
{	
while (isspace(*pcStr)) pcStr++;

int sign = 0;
if (*pcStr == '-') {
	sign = 1;
	pcStr++;
}else if(*pcStr == '+'){
	pcStr++;
} 
while ((*pcStr) == '0') pcStr++;

uint32_t val = 0;
while (*pcStr){
	char ch = *pcStr;
	CHECK_RET_BREAK(isdigit10(ch));

	val = val * 10 + (ch - '0');
	pcStr++;
}

return (sign)?(~val + 1):val;
}

十六进制进制实现

uint64_t _S16toU64(const char* pcStr)
{
	while (isspace(*pcStr)) pcStr++;

	int sign = 0;
	if (*pcStr == '-') {
		sign = 1;
		pcStr++;
	}else if(*pcStr == '+'){
		pcStr++;
	} 

	if (pcStr[0] == '0' && (pcStr[1] == 'x' ||pcStr[1] == 'X')) {
		pcStr += 2;
	}
	while ((*pcStr) == '0')pcStr++;

	uint32_t val = 0;
	while (*pcStr){
		char ch = *pcStr;
		if (isdigit10(ch))
			val = (val << 4) + (ch - '0');
		else if (ch > ('a' - 1) && ch < ('f' + 1))
			val = (val << 4) + (ch - 'a') + 10;
		else if (ch > ('A' - 1) && ch < ('F' + 1))
			val = (val << 4) + (ch - 'A') + 10;
		else break;
		pcStr++;
	}

	return (sign)?(~val + 1):val;
}

数据类型转字符串

#define StrtoS64(str,v)   		do {sscanf(str,"%lld", v); } while (0);
#define StrtoU64(str,v)   		do {sscanf(str,"%llu", v); } while (0);
#define S64toStr(v, buf,n)   do {snprintf(buf, n,"%lld", v); } while (0);
#define U64toStr(v, buf,n)   do {snprintf(buf, n,"%llu", v); } while (0);

数据类型与数组

/*brief    long类型转数组*/
int long2char(uint64_t u64Data,uint8_t* pu8Data) 
{
	CHECK_RET_VAL_P(pu8Data,-PARAM_INPUT_DATA_IS_NULL,"param input data invalid!\n");

#if WOW_BIG_ENDIAN == 1
	byte_set_64_be_impl(pu8Data,u64Data);
#elif WOW_LITTLE_ENDIAN == 1
	byte_set_64_le_impl(pu8Data,u64Data);
#else
	byte_set_64_be_impl(pu8Data,u64Data);
#endif

	return WOW_SUCESS;
}

/*brief    数组转long类型 */
int char2long(uint8_t* pu8Data,uint32_t *pu64Data) 
{
	CHECK_RET_VAL_P(pu8Data && pu64Data,-PARAM_INPUT_DATA_IS_NULL,"param input data invalid!\n");

#if WOW_BIG_ENDIAN == 1
	*pu64Data = byte_get_64_be_impl(pu8Data);
#elif WOW_LITTLE_ENDIAN == 1
	*pu64Data = byte_get_64_le_impl(pu8Data);
#else
	*pu64Data = byte_get_64_be_impl(pu8Data);
#endif

	return WOW_SUCESS;
}

BCD码与字符串

int BCD2String(uint8_t *pu8BcdData, int nBcdLen, uint8_t *pu8StrData, int nStrLen)
{
	int  iPosFlag = 0;
	char cBCD     = 0;

	CHECK_RET_VAL_P(pu8BcdData && pu8StrData ,-PARAM_INPUT_DATA_IS_NULL,"param input data invalid!\n");
	CHECK_RET_VAL_P(2 * nBcdLen <= nStrLen,-PARAM_INPUT_SIZE_IS_SMALL,"param input size invalid!\n");

	for (iPosFlag = 0; iPosFlag < nBcdLen; iPosFlag++)
	{
		cBCD = (pu8BcdData[iPosFlag] >> 4);
		if (0x0f == cBCD){
			break;
		}
		pu8StrData[2 * iPosFlag] = cBCD + '0';
		CHECK_RET_VAL_P(isdigit(pu8StrData[2 * iPosFlag]),-1,"pu8StrData[2 * %d] is not digit!\n", iPosFlag);


		cBCD = (pu8BcdData[iPosFlag] & 0x0f);
		if (0x0f == cBCD){
			break;
		}
		pu8StrData[2 * iPosFlag + 1] = cBCD + '0';
		CHECK_RET_VAL_P(isdigit(pu8StrData[2 * iPosFlag + 1]),-1,"pu8StrData[2 * %d] is not digit!\n", iPosFlag);
		pu8StrData[2 * iPosFlag + 1] = cBCD + '0';
	}

	return WOW_SUCESS;
}

int String2BCD(const uint8_t *pu8StrData, int nStrLen, uint8_t *pu8BcdData, int nBcdLen)
{
int  iPosFlag = 0;

CHECK_RET_VAL_P(pu8BcdData && pu8StrData ,-PARAM_INPUT_DATA_IS_NULL,"param input data invalid!\n");
CHECK_RET_VAL_P(2 * nBcdLen >= nStrLen,-PARAM_INPUT_SIZE_IS_SMALL,"param input size invalid!\n");

for (iPosFlag = 0; iPosFlag < nStrLen; iPosFlag+=2)
{
	CHECK_RET_VAL_P(isdigit(pu8StrData[iPosFlag]),-1,"pu8StrData[%d] is not digit!\n", iPosFlag);

	pu8BcdData[iPosFlag / 2] = pu8StrData[iPosFlag] - '0';
	pu8BcdData[iPosFlag / 2] <<= 4;

	if ((iPosFlag + 1 >= nStrLen)){
		break;
	}

	CHECK_RET_VAL_P(isdigit(pu8StrData[iPosFlag+ 1]),-1,"pu8StrData[%d+ 1] is not digit!\n", iPosFlag);

	pu8BcdData[iPosFlag / 2] += pu8StrData[iPosFlag + 1] - '0';
}

return WOW_SUCESS;
