unsigned char counter=0, led1=0;意思是定义两个无符号字符型的变量，并且给他们赋值。我们知道字符实际上也是整数，因为字符其实就是用ascii码来编码的。
在计算机科学和编程领域,unsigned是一个关键字,用于定义无符号整数类型,无符号整数是一种不包含负数的整数,其值范围从0到该类型的最大正数,这种数据类型在处理需要大量非负数值的应用场景中非常有用,如计数器、索引、内存地址等。 无符号整数的定义和用途 无符号整数通过省略符号位来扩展数值的范围,一个8位的无符号...

String literal should not be assigned to object unless it has type of pointer to const-qualified char. V2533. MISRA. C-style and functional notation casts should not be performed. V2534. MISRA. The loop counter should not have floating-point type. V2535. MISRA. Unreachable code should not...
你也可以写if(counter < 0xFFu)，这也很好，两个操作数本质上都是无符号的。没有MISRA规则“积分...
