CCS/MSP430G2544: MSP430G2544 temperature calibration data

Part Number: MSP430G2544

Tool/software: Code Composer Studio

Hello,

I'm using the built-in temperature sensor in MSP430G2544.

However I couldn't find the Flash address for temperature ADC calibration data in the device datasheet.

It mentions in the user guide that device datasheet will contain the address of calibration data, but I couldn't find any for MSP430G2544.

Your support is appreciated. Thanks.

  • Chapter 24 says:

    The Tag-Length-Value (TLV) structure is used in selected MSP430x2xx devices to provide device-specific information in the device's flash memory SegmentA, such as calibration data.

    The G2544 is not one of those selected devices.

    And section 22.2.8 says:

    Deriving absolute temperature values in the application requires calibration. See the device-specific data sheet for the parameters.

    This is very misleading. There are no temperature parameters mentioned in the datasheet because no calibration was done. If calibration is required, you have to do it yourself.

  • Hey Namh,

    Clemens in correct. This device does not have any temperature calibration data.
