mCookie-CoreRF

mCookie-CoreRF is AVR core board, supporting for 802.15 Wireless Protocol natively. It integrates 802.15.4 Wireless Protocol modules, including ZigBee, MAC/6LoWPAN and RF4CE.

Features

• Integrate 802.15.4 Wireless Protocol modules, including ZigBee, MAC/6LoWPAN and RF4CE.
• Small, cheap, stackable and open；
• Open-source hardware circuit design, and compatible-with-Arduino programming development environment；
• The unified Microduino interface specification, and abundant peripheral modules, which make it can be extended and connected with other modules and sensors which meet the Microduino interface specification, quickly, conveniently and flexibly；

Specification

Adopt ATmega128RFA1 core：

• There are 22 Digital I/O（6 during them support ADC）：
• 2 hard serial ports：
  • UART0_RX：D0
  • UART0_TX：D1
  • UART1_RX：D2
  • UART1_TX：D3
• Support 7 PWM：
  • D4、D5、D6、D7、D8、D9、D10
• 6 external interrupt：
  • Interrupt0 (pin SCL)
  • Interrupt1 (pin SDA)
  • Interrupt2 (pin D2)
  • Interrupt3 (pin D3)
  • Interrupt4 (pin D5)
  • Interrupt5 (pin D6)
• There are 10 Analog I/O ：
  • On the module labeled A0, A1, A2, A3, A6, A7, D8(A8), D9(A9), D3(A10), and D4(A11)；
  • Each provides 10 resolution ratios（that is 0~1024）. By default, the measurement range of analog voltage is the value from GND to VCC；
  • Please refer to analogRead()function for details.
• There is one SPI supporter：
  • On the module labeled D13(SCK),D12(MISO),D11(MOSI),D10(SS).
• There is one I2C supporter：
  • On the module labeled SDA(D18),SCL(D19).

Test

Use the example program “ZigduinoRadioExample” in ZigduinoRadio library to test

void loop() 
{ 
    if (Serial.available()) 
    { 
        ZigduinoRadio.beginTransmission(); 
 
        Serial.println(); 
        Serial.print("Tx: "); 
 
        while(Serial.available()) 
        { 
            char c = Serial.read(); 
            Serial.write(c); 
            ZigduinoRadio.write(c); 
        } 
 
        Serial.println(); 
 
        ZigduinoRadio.endTransmission(); 
    } 
 
    if (ZigduinoRadio.available()) 
    { 
        Serial.println(); 
        Serial.print("Rx: "); 
 
        while(ZigduinoRadio.available()) 
            Serial.write(ZigduinoRadio.read()); 
 
        Serial.println(); 
        Serial.print("LQI: "); 
        Serial.print(ZigduinoRadio.getLqi(), 10); 
        Serial.print(", RSSI: "); 
        Serial.print(ZigduinoRadio.getLastRssi(), 10); 
        Serial.print(" dBm, ED: "); 
        Serial.print(ZigduinoRadio.getLastEd(), 10); 
        Serial.println("dBm"); 
    } 
 
    delay(100); 
} 
 
void errHandle(radio_error_t err) 
{ 
    Serial.println(); 
    Serial.print("Error: "); 
    Serial.print((uint8_t)err, 10); 
    Serial.println(); 
} 
 
void onXmitDone(radio_tx_done_t x) 
{ 
    Serial.println(); 
    Serial.print("TxDone: "); 
    Serial.print((uint8_t)x, 10); 
    Serial.println(); 
}

This example realizes the wireless transmission function. Because Core RF adopts ports to download, you need to stack a Microduino-USBTTL at first： The board card , choose Microduino Core RF.

After downloading programs to two Core-RF, open the serial port monitor, and input “Hello Microduino!”, then you will get the following result:

The test is completed now.
