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?
