PinMux Tool v4 User Guide

Table of Contents


PinMux determines a mux configuration for your system once you’ve specified the peripheral signals your system requires external pinouts for. This determination is automatic based on your requirements - you do not need to manually try multiple configurations or resolve conflicts. Once determined, the tool can either generate source code that configures the device at runtime, or a summary file showing the configuration.

Getting Started

After installing, launch the tool, select your device and hit configure. You'll then see a screen similar to this. The left side lists all the peripheral types available on the device. The middle gives specifics on an individual specific peripheral. The picture on the far right shows what device pins are in use or available. Drawing
To start inputting your system's requirements. Select a peripheral type from the list on the left and select “Add” in the middle column. The tool will automatically select external pins for the signals of that peripheral. Those pins will appear green in the picture on the right. You do not have to select them yourself. Drawing
If your system doesn't need every signal on the peripheral, unselect the signal using the checkbox to its left. The fewer signals selected, the less external pins are used and therefore available for other peripheral signals. Drawing
Some devices may expose Use Cases for some peripherals to allow you to quickly eliminate the signals you won't need.
