规则3. 变量名不能使用编程语言的保留字。例如:if、else、int... 解决方案 看了命名规则之后,你发现之前的代码在给变量命名的时候,有一个错误的命名:val%,现在将'%'删除或者换为字母(a-z A-Z),数字(0-9),下划线(_)的组合,来看看更改后的效果吧。 标签:...

output is in the range 0..1023, so the Arduino does the appropriate shifting to get the output from the filter back into the same range. The filter input and output values are stored as 16-bit ints but some of the maths must be done using 32-bit ints to avoid problems with ...
