Other Parts Discussed in Thread: TMP118
Tool/software:
Hi expert,
May I know if we have the USB command/driver of USB to I2C for TMP118EVM can share with customer for system integration development?
Thanks,
Allan

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. //Author: Harry Gill //v0.2 #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 #define CONFIG_OS 0x1 // // 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; }
