从遥控直升机收集协议 [英] Gathering protocol from remote control helicopter
问题描述
我有一个（S107G）迷你直升机，和一个Arduino。这种可能性听起来很有趣。于是我动身去寻找数据从控制器转移与IR直升机的协议。我用这个code，试图弄清楚它的东西。
I have a (S107G) mini helicopter, and an Arduino. The possibilities sounded quite fun. So I set off to find the protocol for the transfer of data from controller to helicopter with IR. I used this code to try to figure out something of it.
void setup()
{
Serial.begin(9600);
pinMode(12, INPUT_PULLUP); // 12 is IR sensor
}
void loop()
{
Serial.print(digitalRead(12) ? LOW : HIGH);
delay(1);
}
显然有许多漏洞与此有关。
Obviously there a number of flaws with this.
-
延迟（1）;是任意选择的，我不知道在传输什么高速数据的方式 - 这可能是模拟输入。 （虽然我对此表示怀疑，因为大多数红外传感器，我发现不支持）
- 我不知道什么时候一个数据包开始或结束的方式。
delay(1);is arbitrarily chosen, I have no way of knowing at what speed data is transmitted.- It could be an analog input. (Though I doubt it, as most IR sensors I found don't support that)
- I have no way of knowing when a "packet" starts or ends.
如果您有任何的如何做到这一点的想法
我更AP preciate它。谢谢！
If any of you have an idea of how to do this I would much appreciate it. Thanks!
编辑：我发现<一个href=\"http://stackoverflow.com/questions/14774794/how-to-determine-checksum-from-de$c$cd-ir-remotes\">this在SO ，听起来很不错，但他并没有进入深度来他是如何做到的，什么他的调查结果（速度等）
I found this on SO and it sounds very nice, but he didn't go into depth as to how he did it, and what his findings were (speed, etc.)
推荐答案
您可以找到完整的code库的在这里我github上中，你会发现IRsendDemoHelicopter.ino和IRrecvDump.ino的例子。这些和IRremote.cpp应该回答你的问题。我有它在我的计划（的某个时候），以实现在一个Esplora发射器。
You can find the complete code library here on my GITHUB in which you will find the examples of IRsendDemoHelicopter.ino and IRrecvDump.ino. These and the IRremote.cpp should answer your questions. I have had it on my plan (for sometime) to implement the transmitter on an Esplora.
下面是微秒，在发现的https：// github.com/mpflaga/Arduino-IRremote/blob/master/IRremoteInt.h#L192
#define SYMA_UPDATE_PERIOD_CH_A 120 // 0
#define SYMA_UPDATE_PERIOD_CH_B 180 // 1
#define SYMA_HDR_MARK 2000
#define SYMA_HDR_SPACE 2000
#define SYMA_BIT_MARK 320
#define SYMA_ONE_SPACE 687
#define SYMA_ZERO_SPACE 300
和这里为两个R3和R5的比特的图案。我相信R5是生产中最常见的是。
and here is the pattern of bits for both the R3 and R5. I believe the R5 is the most common being in production.
union helicopter {
uint32_t dword;
struct
{
uint8_t Throttle : 7; // 0..6 0 - 127
uint8_t Channel : 1; // 7 A=0, B=1
uint8_t Pitch : 7; // 8..14 0(forward) - 63(center) 127(back)
uint8_t Pspacer : 1; // 15 na
uint8_t Yaw : 7; // 16..22 127(left) - 63(center) - 0(right)
} symaR3;
struct
{
uint8_t Trim : 7; // 0..6 127(left) - 63(center) - 0(right)
uint8_t Tspacer : 1; // 7 na
uint8_t Throttle : 7; // 8..14 0 - 127
uint8_t Channel : 1; // 15 A=0, B=1
uint8_t Pitch : 7; // 16..22 0(forward) - 63(center) 127(back)
uint8_t Pspacer : 1; // 23 na
uint8_t Yaw : 7; // 24..30 127(left) - 63(center) - 0(right)
} symaR5;
};
但它始终是可能的，他们推出了一个新的模式。
but it is always possible they have come out with a new pattern.
