Hi, this is Gaurav.

Please guide me for the SMBus protocol. MXL90614 infrared temp sensor. I want to communicate the sensor with the PSoC and then send the data to the BLE.

 

Please do guide me.

I'm attaching the TempSensor's Data sheet.

Thank you

Hi Tom,

I understand the I2C module in the CyComponentLibrary can't write to a device with address 0x00 because valid addresses for the API calls are 8 to 120.  How were you able to change the device address of the IR sensor from the factory default of 0x00 to 0x5A?  Did you use a different SMBus master to do this?

 

Thanks,

-Ted

The SMBus is compatible to I2C, so you may use an I2C Master component to talk to the MXL90614. Read the I2C datasheet thoroughly and understand how it works.
