对于基于 Arduino Sketch 的测光表，'loop'之外的功能不会触发/触发

我对Arduino很陌生。我对Java和ActionScript3有更多的经验。我正在用Arduino Uno和TAOS TSL235R光频转换器建造一个测光表。

我只能用不同的传感器找到一个图图里亚尔，所以我正在努力转换我需要的东西，让它全部工作（也就是一些复制和粘贴，可耻的是，但我是新手）。

有三个部分：这是Arduino和Taos TSL230R光传感器系列的第一个教程：入门。

摄影转换：Arduino和TSL230R：摄影转换。

起初，我可以返回TSL235R传感器创建的频率值，但一旦我尝试添加用于摄影转换的代码，我只返回了零，主循环之外的任何功能似乎都没有启动，因为我的Serial.Println()没有返回任何东西。

比起我的数学是否完美，我更关心的是激发函数在ActionScript和Java中，有函数的事件侦听器等等，我是否需要声明函数以使其在C/C++中激发？

基本上，我如何确保我的所有函数都使用C编程语言？

我的Arduino素描：

#define TSL_FREQ_PIN 2
// Our pulse counter for our interrupt
unsigned long pulse_cnt = 0;
// How often to calculate frequency
// 1000 ms = 1 second
#define READ_TM 1000
// Two variables used to track time
unsigned long cur_tm = millis();
unsigned long pre_tm = cur_tm;
// We'll need to access the amount of time passed
unsigned int tm_diff = 0;
unsigned long frequency;
unsigned long freq;
float lux;
float Bv;
float Sv;
// Set our frequency multiplier to a default of 1
// which maps to output frequency scaling of 100x.
int freq_mult = 100;
// We need to measure what to divide the frequency by:
//   1x sensitivity =   10,
//  10x sensitivity =  100,
