calibrate Data in MSP430

Other Parts Discussed in Thread: MSP430G2231

Hi fortum members:

 TI has calibrate some data such as buit_in temperature Sensor,  REF, ADC. for customer using.

what  I want to know is that these data were sotred in which section in the MSP430. and how to use in my application .

The F5xx user guider has tell us a lot about this,however, what about the F1xx，G2xx, F2xx, F4xx?  I can't find any document mention these serises.

Thanks in advance.

    All calibration data are stored in the INFORMATION MEMORY section.   The physical address is flask 0x1000 ~ 0x1FFF.

    You can find detail difination from .h file for the device.  Exp: for MSP430G2231 using MSP430G2231.h file.  Open the file and search "CAL" you will get the information.

    I think the family users guides have some information.  For example, slau144e.pdf for the MSP430x2xx Family has a section describing the calibration data, 'TLV Structure'. 

    Specific device data sheets detail the information also, such as in SLAS541E for the MSP430F241x / 261x series.  There is a section detailing the calibration data and the TLV structure used. 

    Additionally, some code examples use the calibration values, such as for setting up the DCO for 8MHz clock speed.

    Hope that helps!

    The F1 series has no calibraiton data or other information at all.

    The other families have either a TLV structure or some values (usually just for 1MHz and perhaps 4MHz DCO settings) in the info memory.
    The information about it is eithe rin the family users guide or in the device datasheet. However, I must admit that it isn't easily found.
