我正在寻找可以执行此示例的示例代码或代码。
我有2个字符缓冲区
Character_Buf1=<**DATA1,1**> Format used to receive character from Serial Receive
character Buf2=<**DATA1,1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val2**>
其中val1是整数值。我需要将它转换为一个字符并附加在Buf2
中If Externally send request <DATA1,1>
if Char_buf1[First_6character]=Char_buf2[First_6character]
Char_Buf[100]=<**DATA1,1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val1,val2**>
print Char_buf2[]
其他打印字符缓冲区不匹配。
If serial request
char_buf1
其中charact_buf1是从Arduino委员会发送的sereial请求。
从我从堆栈溢出中找到的代码中，我能够按预期发送请求＆amp;在案件之间切换。如何通过值转换实现字符缓冲区数据存储？

我编辑了代码。在这里，我可以切换模式。但是如何将数字存储到 Serial_Command1（）函数的字符缓冲区中。我无法将商店数据打印到字符缓冲区数组中。
