8:00 – FP

• Installing arduino drivers and generally setting up environment.Done
• Working on understanding ASCII serial communications
• Serial echo:

  const unsigned int BAUD_RATE = 9600;
  
  void setup(){
    Serial.begin(BAUD_RATE);
  }
  
  void loop(){
    int numChars = Serial.available();
    if(numChars > 0){
      Serial.print("numChars = [");
      Serial.print(numChars);
      Serial.print("] string = ");
      for(int i = 0; i < numChars; ++i){
        // Serial.read returns the first byte (int?) of incoming serial data
        // available (or -1 if no data is available) - int
        char inp = Serial.read();
        Serial.print(inp);
      }
      Serial.println();
      Serial.println("ready");
    }
  }

• Turns out that I don’t have Visual Studio here. Talking from C++ will have to wait until this afternoon.
• The arduino book references arduino-serial.c for example c code. The book’s code is here.
