我已经浏览了其他问题,我真的找不到任何可以帮助我的东西。我仍然是Arduino的新手,几年来还没有使用C语言,所以我是一个生锈的...
我的问题是在包含所需的所有库后立即在主文件中初始化类变量" TCS"。它给了我" adafruit_tcs34725"不命名类型。"
它应该调用我的父类中的功能,以初始化变量,正确?
另外,请记住我无法测试/调试代码的其余部分,因此不要讨厌是否也有任何错误:P我包括了主文件和2个库,添加了。
这是用于运行Arduino的主C文件。main.h
#include <Adafruit_TCS34725.h>
#include <Adafruit_TCS34725_CPP.h>
#include <Servo.h>
#include <Wire.h>
/* Initialise with default values (int time = 2.4ms, gain = 1x) */
Adafruit_TCS34725 tcs = Adafruit_TCS34725();
/* Initialise with specific int time and gain values */
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_700MS, TCS34725_GAIN_1X);
void setup(void) {
Serial.begin(9600);
if (tcs.begin()) {
Serial.println("Found sensor");
} else {
Serial.println("No TCS34725 found ... check your connections");
while (1);
}
// Now we're ready to get readings!
}
void loop(void) {
uint16_t r, g, b, c, colorTemp, lux;
tcs.getRawData(&r, &g, &b, &c);
colorTemp = tcs.calculateColorTemperature(r, g, b);
lux = tcs.calculateLux(r, g, b);
Serial.print("Color Temp: "); Serial.print(colorTemp, DEC); Serial.print(" K - ");
Serial.print("Lux: "); Serial.print(lux, DEC); Serial.print(" - ");
Serial.print("R: "); Serial.print(r, DEC); Serial.print(" ");
Serial.print("G: "); Serial.print(g, DEC); Serial.print(" ");
Serial.print("B: "); Serial.print(b, DEC); Serial.print(" ");
Serial.print("C: "); Serial.print(c, DEC); Serial.print(" ");
Serial.println(" ");
}

您修改的原始示例可以很好地编译。我很确定您会遇到错误,因为您尚未正确安装库。
假设您的素描本文件夹是:
C:UsersYourUserNameDocumentsArduino
然后必须放入文件Adafruit_TCS34725.cpp
和Adafruit_TCS34725.h
,例如:
C:UsersYourUserNameDocumentsArduinolibrariesAdafruit_TCS34725
如果您在放置这些文件时正在运行Arduino IDE,请重新启动。最后一个目录名称可以不同,但只能包含字母,下划线和数字。如果您从Github下载了此库,则可能是Adafruit_TCS34725-master
后的文件夹名称,这是无效的,因为它包含-
。如果还不清楚,这里有一个库安装教程。
其他,然后在您的修改中:#include <Adafruit_TCS34725_CPP.h>
是不必要的,您有两个带有名称tcs
