SPI Initializes four chip select pins

fernando_barrio — Wed, 02 Jan 2019 22:13:54 GMT

Hi,

I am working with SPI on the S32K, is there any way that I don't have to initialize all four chip select pins? I want three instances of SPI communication each with only one slave/master, but now I have a lot of pins that I cannot use. Please let me know if you have any suggestions.

Thank you,

Fernando

Hello fernando.barrios@uwaterloo.ca‌,

In the current version of the toolbox there is no such option, but I will post on the Hotfixes page next week an update so you can do just that - it will be there probably Tuesday; I'll post here a link to it as it is made available.

Kind regards,

Razvan.

Hello fernando.barrios@uwaterloo.ca‌,

I've updated this hotfix (#2) so you can select None on the pins you don't need to use. Please follow the instructions there and let me know if you encounter any issues.

Kind regards,

Razvan.
