数据类型转换问题

刘小白_xl · 发表于 2016-12-16 18:53:11

本人现在正在使用射频模块RC522，接收卡号，在串口接收到一系列的十六进制数，这是卡的号码 515937D5EA --------->0x51,0x59,0x37,0xD5,0xEA，我想帮这个卡号编成字符串:'5','1','5','9','3','7','D','5','E','A'，然后在LCD12864上显示，尝试了好长时间，一直都是乱码。。。麻烦大神们帮我想想办法，谢了

这个rfid.serNum返回的结果应该是unsigned char类型的了，你看一下能不能直接用，或者是我记得如果LCD1692用IIC转接板的话可以直接发送char类型的，就能识别，或者是lcd.print/lcd.write里面试试按照串口那样加[,HEX]

我用的是12864 没有用1602

我先跟你说这么一个问题，serNum已经是unsigned char类型的了，我看到你又定义了一个charserNum的字符串，然后去做了一个处理是吧。
for(int i=0;i<9;i+=2)
{
charserNum= rfid.serNum/4;
charserNum[i+1]= rfid.serNum%4;
}
我想问你的是，你知道rfid.serNum返回的是什么吗，你有注意到你的程序上面串口输出卡号的时候用的是rfid.serNum[0]这一类的吗？
还有，对于char类型变量，我想知道的是，你认为char类型变量÷4或者求余4之后的结果是什么？因为我记得是，虽然它是char类型变量，但他是用ascii码表存储的数字，你直接将ascii的数字÷4，你看一下表是不是和你的乱码一样。。。
检查的时候记得用十进制检查。。。虽然串口输出是十六进制，但好像存储的数字是十进制的
