GenericSPI: No inherited component assigned

asfarley — Wed, 22 Feb 2017 21:41:22 GMT

I'm trying to configure the SPI1 bus using the FRDM-K22F. The PE component GenericSPI gives an error when added to the design: No Inherited Component Assigned. The SPI Channel dropdown does not contain any values.

Configuring the SPIMaster_LDD component seems to work fine. I've already configured the SPI1 pins in the PinSettings component.

Why can't I configure the GenericSPI component? Is there something I need to do first?

Hi Alexander,

The 'GenericSPI' component is for legacy HCS08 and ColdFire devices, and the 'SPI channel' points to their Init_SPIxxx component. So it is not applicable for Kinetis (as the API is different). The documentation for the component was not clear abou this (I appologize!), so I have updated it.

If you want to use a software (bit banging) SPI implementation, you could use the GenericSWSPI too:
