xchip bonus 4

Bonus Lab 4: Serial Monitor to OLED

To perform this lab you will need:

1. IP01 xChip- USB module
2. CW01 xChip- WiFi module and processor
3. OD01 xChip- OLED display module
4. SW01 xChip- Humidity, Pressure, and Temperature Sensor
5. 3 Connector pieces

---

Assembly

Click your pieces together using the connector pieces.

The Code

Copy and paste the code from below into your Arduino IDE. Verify and upload the program onto your xSystem.

NOTE: Your IP01 USB module has two switches. Be sure they are set to "B" and "DCE." The xChip will not be able to receive code if it is in any other configuration.

// Establish Serial Monitor Connections, Send text to OLED
// Uses CW01, OD01 and IP01 xChips

  #include <xCore.h>     //This library allows us to use the CW01 processor
  #include <xOD01.h>     //This library allows us to use the OD01 screen
  #include <xSW01.h>     //This library allows us to use the weather sensor

  String text;          //Initialize variable

void setup() {
  Wire.begin(2,14);     //Starts the xChips talking to each other
  Serial.begin(9600);   //Define serial monitor connection parameters
  OLED.begin();         //Turn on the OLED Screen

//These instructions will display on the OLED screen
//Instructions to establish serial connection
  OD01.println("Flick the switch");
  OD01.println("from B to A");
  OD01.println();
  OD01.println("Open the Serial");
  OD01.println("Monitor and type 'go'");

  while (!Serial.available()){
  //Wait for serial monitor to be opened
    delay(1000);
  }

// Type any message into the Serial Monitor to establish communication
 Serial.readString();

//This prints to the serial monitor  
  Serial.println("     Connection Established   ");
  Serial.println("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
  Serial.println("         XinaBox OLED         ");
  Serial.println("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");

  delay (1000);   //Dramatic pause

  Serial.println("Type a message and look at the OLED!");    //Initial instructions
  Serial.println("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");    //Decorative divider

  OD01.clear();   //Clear the text from OLED screen
}

void loop() {

  text = Serial.readString();   //Get text from the Serial Monitor

  if (text != 0){
  //If something is typed in, follow these instructions
    OD01.println(text);
    Serial.println("Type a new message!");    //New Instructions
    Serial.println("~~~~~~~~~~~~~~~~~~~");    //Decorative divider  
  }
}

Follow the instructions on the OLED. You should then be able to display any message you want!
