TMP118EVM: USB Command Driver

Hello Allan,

Are you asking for separate code the customer can use for the TMP118 device? Or the source code for the TMP118EVM software?

I have attached some C-based sample code for Arduino below. If the customer needs help with developing a C-based driver, I highly encourage checking out our SysConfig page.

//TMP118 Example Code to allow users to read from the TMP118 temperature sensor using a C-based program.

 #include <Wire.h>

//|| Device Definitions ||\\

// Register Configurations
#define DEVICE_CONFIG_REG_ADDR 0x0 //
#define DEVICE_ADDR 0x48 //
#define DEVICE_TEMP_REG_ADDR 0x0 //

// Device Mode Options \\

// One-Shot

// Continuous
#define CONFIG_CONTINUOUS 0x0 //


void setup() {
  
  // put your setup code here, to run once:
  Wire.begin();
  Serial.println("TMP118 Arduino Example");
  Serial.begin(9600);

  //initialize device
  device_init();
  
  //wait 8ms
  delay(8);

}

void loop() {

  // put your main code here, to run repeatedly:

  // Pass device address and temp reg addr
  int16_t tempData = getData(DEVICE_ADDR, DEVICE_TEMP_REG_ADDR);

  float celcius = tempData * 0.0078125;

  Serial.print("Temp (C): ");
  Serial.println(celcius);

  //wait one second until next temp read
  delay(1000); 

}

    // initialize device and load configuration into sensor
    void device_init(){

      //initiate contact with sensor
      Wire.beginTransmission(DEVICE_ADDR);

      //write to config register
      Wire.write(DEVICE_CONFIG_REG_ADDR);
      
      //write OS mode to config register
      Wire.write(CONFIG_OS);
      
      Wire.endTransmission();

    }

    int16_t getData(int8_t sensorAddr, int8_t tempReg) {
      
      Wire.beginTransmission(sensorAddr);
      Wire.write(tempReg);
      Wire.endTransmission();
      Wire.requestFrom(sensorAddr, 2);

      int16_t bytes = Wire.read() << 8;
      bytes |= Wire.read();

      return bytes;
      
    }
