IPM problem using EMIOS_ic

Hello,

I'm trying to use EMIOS_IC component but it's not working..

I'd like to read the frequency of a square wave.

I have a DEVKIT-MPC5748G and use S32-Design with processor expert.

EMIOS_DRV_IC_InitInputCaptureMode(INST_EMIOS_MC1, 11, &eMIOS_Ic1_ICChnConfig0);

EMIOS_DRV_IC_GetLastMeasurement(INST_EMIOS_MC1, 11, &Period);

The input signal period is 50ms but 'Period' variable is always 0.

Other doubt is if the emios_qd component works? If so, is there any example of how to use?

Thanks,

Best Regards

João Paulo

Hi,

you can refer to "emios_ic_mpc5748g" demo example available in S32 Design Studio.

The eMIOS module on the MPC5748G does not support quad decode mode.
