不好意思小弟又来请教了
这次想实现的功能是开启程式后透过廻圈传递Define的值给程式
然后程式将值透过位元运算编译成我想要的资料格式 8个Byte的资料 然后再转成16进制的资料格式发送给机器
编译之后没有提示语法错误，小弟苦思费解还是找不出问题所在

报错

小弟试了好久 把每段程式都遮罩起来一个一个Debug

发现好像是这段有问题


WidthCode[7]=(WidthCode[0]^WidthCode[1]^WidthCode[2]^WidthCode[3]^WidthCode[4]^WidthCode[5]^WidthCode[6]) | 0x01;

但是语法上没啥错误啊 搞不懂...
