I'm working with MM9Z1J638 MCU.

In the demo there is a structure defined for calibration data as below.

// --------------------------------------------------------------------

/*! \brief Sets up the next channel for conversion

- loads device calibration values (from IFR -> B_COMP_xxx registers)

- loads incremental system calibration values (gainsteps and offsetsteps)

@Param SensorChannelchannel

void CsenseSetupChannel(TYPE_CSENSE_CHANNEL Channel) {

B_COMP_IG4 = IFR_COMP_IG4 + CalibValues.isense.gainsteps;

B_COMP_IG16 = IFR_COMP_IG16 + CalibValues.isense.gainsteps;

B_COMP_IG64 = IFR_COMP_IG64 + CalibValues.isense.gainsteps;

//B_COMP_IG256 = IFR_COMP_IG256+ CalibValues.isense.gainsteps;

B_COMP_TIG4 = IFR_COMP_TIG4;

B_COMP_TIG16 = IFR_COMP_TIG16;

B_COMP_TIG64 = IFR_COMP_TIG64;

B_COMP_TIG256= IFR_COMP_TIG256;

// select "window (page)" then write value

B_ACQ_GAIN = GAIN256;

//B_COMP_IO = CalibValues.isense.offsetsteps;

B_ACQ_GAIN = GAIN64;

B_COMP_IO = CalibValues.isense.offsetsteps / 4;// offset for gain 64 = offset for gain 256 / 4

B_ACQ_GAIN = GAIN16;

//B_COMP_IO = CalibValues.isense.offsetsteps / 16;// offset for gain 16 = offset for gain 256 / 16

B_ACQ_GAIN = GAIN4;

//B_COMP_IO = CalibValues.isense.offsetsteps / 64;// offset for gain 4 = offset for gain 256 / 64

}

I can't locate the definition of this structure from the demo code. Where can I get this information?

Regards,

Bruce

Hello bjs

Could you share the name of the demo you're using?

I will be waiting for your response

Have a great day and best of luck.
