红外遥控支持库与“多线程”支持库冲突导致接收红外乱变
本帖最后由 hejie13250 于 2016-7-29 17:32 编辑在淘宝上买了一个RGB灯环，每个灯（12个）都带有微型控制器，只用一个IO就可以搞定。
想通过一个4*4的矩阵键盘控制灯环的变色样式，其中按键“D”为关闭所有灯。
现在增加红外遥控来控制，和4*4的矩阵键盘一样。
此时问题来了，不加“多线程”库，读取的红外信号是正常的，加上后读取的信号值就会乱变，下图为多次按下遥控上的“9”后接收到的信号
经排除确认是红外遥控支持库与“多线程”支持库冲突导致，还望大神支招！！！
代码如下：
主体
#include <SCoop.h>
char style = 'd';//灯环样式 style 默认为关闭状，按 d 键或 遥控 EQ关闭
//初始化功能
void setup() {
Serial.begin(9600);
mySCoop.start();//启用“多线程”
}
void loop()
{
yield();
}
遥控接收
#include <IRremote.h>
int RECV_PIN = A0;
IRrecv irrecv(RECV_PIN);
decode_results results;
defineTask(IRremote);
void IRremote::setup()
{
irrecv.enableIRIn(); // 开始接收信号
}
void IRremote::loop()
{
if (irrecv.decode(&results))
{
switch (results.value)
{
//灯环样式 style 默认为关闭状态，按 d 键或 遥控 EQ关闭
case 16761405: style = 'd'; break; // PLAY
case 16769055: style = 'c'; break; // VOL-
case 16754775: style = 'b'; break; // VLO+
case 16748655: style = 'a'; break; // EQ
case 16738455: style = '0'; break; // 0
case 16750695: style = '*'; break; // 100+
case 16756815: style = '#'; break; // 200+
case 16724175: style = '1'; break; // 1
case 16718055: style = '2'; break; // 2
case 16743045: style = '3'; break; // 3
case 16716015: style = '4'; break; // 4
case 16726215: style = '5'; break; // 5
case 16734885: style = '6'; break; // 6
case 16728765: style = '7'; break; // 7
case 16730805: style = '8'; break; // 8
case 16732845: style = '9'; break; // 9
default : break;
}
//Serial.println(style + "" + results.value);
Serial.print(style);
Serial.print("");
Serial.println(results.value);
irrecv.resume(); //接收下一个信号
}
}
按键部分
//按键4*4定义
const int numRows = 4;//定义4行
const int numCols = 4;//定义4列
const int rowPins = {4, 5, 6, 7}; //设置4*4按键对应的引脚
const int colPins = {8, 9, 10, 11};
const int debounceTime = 20;//去抖动时间长度 20ms
const char keymap = { //键值，可以按需要更改
{ '1', '2', '3', 'a' },
{ '4', '5', '6', 'b' },
{ '7', '8', '9', 'c' },
{ '*', '0', '#', 'd' }
};
defineTask(Key);
void Key::setup()
{
for (int row = 0; row < numRows; row++)
{
pinMode(rowPins, INPUT);
digitalWrite(rowPins, HIGH);
}
for (int column = 0; column < numCols; column++)
{
pinMode(colPins, OUTPUT);
digitalWrite(colPins, HIGH);
}
}
void Key::loop()
{
char key = getkey();
if (key != 0)
{
Serial.print("Got key ");//串口打印键值
Serial.println(key);
style = key;
}
}
//读取键值程序
char getkey()
{
char key = 0;
for (int column = 0; column < numCols; column++) {
digitalWrite(colPins, LOW);
for (int row = 0 ; row < numRows; row++) {
if (digitalRead(rowPins) == LOW) { //是否有按键按下
sleep(debounceTime);
while (digitalRead(rowPins) == LOW) //等待按键释放
;
key = keymap;
}
}
digitalWrite(colPins, HIGH); //De-active the current column
}
return key;
}

代码和要用的库
自己顶！！！！！！ 我才刚刚接触Arduino，还暂时不能回答您的这个问题。
不过，我正在到处找多线程库SCoop.h，想开发一个小程序。
您能不能把这个SCoop.h库发给我一份？非常感谢！
