如何将uchar数组转换为字符串 [英] how to convert array of uchar to string
问题描述
你好
我是C的新手并且不确定如何完成以下任务：
我有以下c代码，在centos ver 3.4下，使用gnu gcc编译：
uchar sn [8];
//读数
sn [0] = 0x10;
sn [1] = 0x2E;
sn [2] = 0x22;
sn [3] = 0x47;
sn [4] = 0x00;
sn [5] = 0x08;
sn [ 6] = 0x00;
sn [7] = 0x35;
我想将上面的数组转换成Ascii字符串，有什么简单的方法吗在C中实现这一点？
最终我想做以下事情：
query ="插入测试（读取）值（sn） ）" ;;
//我希望将其格式化为插入测试（读取）值（'''3500080047222E10''）"
// I明白c不会插入数组''sn''的值，不像php或其他胶水语言...我希望有一些方法实现这个目标..
do_this_query（查询）;
任何帮助都将不胜感激。
hello
I am new to C and not sure how to go about getting the following accomplished:
I have the following c code, under centos ver 3.4, using gnu gcc to compile:
uchar sn[8];
// readings
sn[0] = 0x10;
sn[1] = 0x2E;
sn[2] = 0x22;
sn[3] = 0x47;
sn[4] = 0x00;
sn[5] = 0x08;
sn[6] = 0x00;
sn[7] = 0x35;
I want to convert the above array into an Ascii string, is there any simple way of achieving this in C?
ultimately i want to do the following:
query = "Insert into test (reading) values(sn)";
// i want to get it formated as "Insert into test (reading) values (''3500080047222E10'')"
// I understand that c will not insert the value of the array ''sn'', unlike php or other glue languages...i am hoping there is some way to achieve this..
do_this_query(query);
any help would be appreciated.

您好，
您能发布完整的代码吗？
我可以从哪里得到这些值吗？
Hi,
Can you post your full code?
Can I know from where you are getting these values?

当然。
我的以下代码是di来自Dallas / Maxim'网站的rect副本，我已经尝试将Mysql c api合并到其中，所以我可以直接将测量的温度信息发送到sql表。
对于来自dallas的全源代码，请访问以下网站获取他们的sdk

以下是我的黑客c代码，请记住我不是程序员，所以我对这个东西很新。对于来自Dallas的原始代码，您可能希望从上面的sdk中看到temp.c。
Sure.
My following code is a direct copy from Dallas/Maxim''s site, I have tried to incorporate the Mysql c api in it as well so I could directly send the measured temperature information to a sql table.
for the fullsource code from dallas, please visit the following site to get their sdk

Following is my hacked c code, please bear in mind I am not a programmer, so I am pretty new to this stuff. For the original code from Dallas, you may want to see the temp.c from the above sdk.
