arduino代码
以下是基于Arduino的代码实现:
```C++
#include <SoftwareSerial.h>
#define RX_PIN 2
#define TX_PIN 3
SoftwareSerial mySerial(RX_PIN, TX_PIN);
unsigned char Comm_Head[6] = {0xAA, 0x6F, 0x00, 0x00, 0x00, 0x24};
unsigned char Comm_End[4] = {0xCC, 0x33, 0xC3, 0x3C};
void setup() {
Serial.begin(9600);
mySerial.begin(9600);
}
void loop() {
unsigned char data[100];
int data_len = 0;
// Wait for data
while (mySerial.available() == 0) {}
// Read data until the end of the packet
while (mySerial.available() > 0) {
data[data_len] = mySerial.read();
data_len++;
// Check if we have received the packet end
if (data_len >= 4 &&
data[data_len - 4] == Comm_End[0] &&
data[data_len - 3] == Comm_End[1] &&
data[data_len - 2] == Comm_End[2] &&
data[data_len - 1] == Comm_End[3]) {
// Remove packet end from data
data_len -= 4;
// Find packet start
int start_index = -1;
for (int i = 0; i <= data_len - 6; i++) {
if (data[i] == Comm_Head[0] &&
data[i + 1] == Comm_Head[1] &&
data[i + 2] == Comm_Head[2] &&
data[i + 3] == Comm_Head[3] &&
data[i + 4] == Comm_Head[4] &&
data[i + 5] == Comm_Head[5]) {
start_index = i;
break;
}
}
// If packet start found
if (start_index != -1) {
// Remove packet header from data
data_len -= start_index;
for (int i = 0; i < data_len; i++) {
data[i] = data[i + start_index];
}
// Process data
for (int i = 0; i < data_len; i++) {
// Do something with each byte of data, for example:
Serial.print(data[i], HEX);
Serial.print(" ");
}
Serial.println();
}
// Clear data buffer
data_len = 0;
}
}
}
```
这个代码使用了SoftwareSerial库来模拟一个串口,从而接收数据。在loop()函数中,我们等待数据的到来,然后从串口中读取数据,并将其存储在一个缓冲区中。我们在缓冲区中查找包头和包尾,如果找到了一个完整的数据包,我们将从中提取有效数据并进行处理。在这个例子中,我们将有效数据打印到串口监视器中,以16进制形式显示每个字节。
当然,这只是一个简单的例子,你可能需要根据你的具体需求进行修改和扩展。
