eMIOS Register Access

Bobkat — Tue, 07 Dec 2021 16:35:00 GMT

Hi,

Is there a way I can access eMIOS registers, e.g. eMIOS_0.MCR_B.GPREN etc... in addition to using one of the SDKs.

I need low-frequency pwm (50-200Hz) for the application and have been advised to avoid using the SDK for this purpose.

I've managed to get the code working based on one of the emios example projects.

The problem I'm encountering is that if I've configured the project to use one of the SDKs (SDK_S32_PA_15), as soon as I include 'project.h' for the emios code as is required by the example , I get a mass of errors related to redefinition of variables etc. If I remove 'project.h' in favour of 'Cpu.h', the compiler can't find the register definition I need for configuration.

I would greatly appreciate any help on this matter.

Best regards

Rob

Hi,

yes, you can access eMIOS registers in SDK code too. Just follow registers definition in respective header file. So you can have e.g.

eMIOS_0->MCR |= eMIOS_MCR_GPREN(1);
eMIOS_0->MCR |= eMIOS_MCR_GPREN_MASK
