Int Array To Hex String

//All checks went fine, convert data
for (i = 0; i < hexLength; i++)

总结
根据上面两个例子
只要将byte GBF_Convert_ByteArrToHexStr(byte rawData[], dword datalen, char outHexStr[])
改为byte GBF_Convert_LongArrToHexStr(long rawData[], dword datalen, char outHexStr[])
然后再将const byte dataType = 4;改为const byte dataType = 8;即可实现long 整型数组转为hex字符串。
Hex字符串转为 整型数组（byte,int,long,dword）

总结
如果是想实现 Hex String To long array ,只需要将byte GBF_ConvertHexStrToIntArray(char hexRawData[], int outByteArr[])改为byte GBF_ConvertHexStrToLongArray(char hexRawData[], long outByteArr[])
int outdword; const byte dataType = 4;改为long outdword; const byte dataType = 8;
