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,

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.

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.
