使用 ADC对NTC热敏电阻查表，数组设置出错

使用ADC的对NTC热敏电阻查表得出实际温度。通过excel表格已经得出温度和AD值的关系，思路是通过获取AD值和表中AD值对比，得知获取AD值在表中的位置，从而得知实际温度。
但是在rebuild时有两个error和一个warning。搞了两天，看了很多资料，还是不能解决。期望论坛的大神可以帮忙看看。
本人在Github上开源了这个项目：https://github.com/jack0915/PWM_fan_controller 有兴趣的同可以去看看。

错误信息如下：

main.c(29): error: #146: too many initializer values
这个已经解决了，数组数量定义错了，不是89个，应该是94个。
有没有其他方便点的方法可以点出数量呢？

不写数组的容量，直接定义成[]

这玩意你自己看看就好了。错误就是形参应该是指针变量，你调用给的是一个u16类型的
