Sigrok Decoder for Infineon SWI

Instructions

First install sigrok, either:

sudo apt-get install sigrok

or download PulseView directly

Next clone this directory:

git clone https://github.com/JonasAlaif/sigrok-infineon-swi.git
cd sigrok-infineon-swi/

Then to run you can use:

SIGROKDECODE_DIR=$(pwd)/decoders pulseview -i cap_*.sr

This will open all 4 cap_ files, each is unique. If you downloaded the PulseView AppImage then replace pulseview above. The SIGROKDECODE_DIR var is needed to add the custom decoder.

Inside PulseView click the add protocol decoder button (rightmost) and select SWI. This will add a new channel SWI, below DIN 0 (SWI) and DIN 4 (UART).

The captured DIN 0 (SWI) channel should now be decoded here. Zoom in with scroll to view at different levels. If you need to change the channel being decoded, click on SWI and select a different SWI channel.

Note; the captured trace has been included in this repo to save you having to convert it to a sigrok format. If you do not wish for this to be publicly available please let me know.
