Configuring TWIS

Hello

I'm using the NRF52832 with softdevice 132.  My SDK version is 15.3.  My platform is WIndows 10.  

I am having trouble configuring the TWIS.  I've followed the instructions in the info center.  They are vague at best.  I could use a step by step procedure.

In addition, I'm using the template example and am doing my best to configure the NRFX directives.  I've tried to source some of the code from the master/slave example in the peripheral examples folder.  However, this code is configured using the older NRF_DRV  directives. 

thanks

Shawn
