Precision32™ 32-bit Microcontroller Software Tools

Software Tools

Silicon Labs offers advanced software development tools, available at no charge to developers. These tools unlock the power and flexibility of the Precision32™ 32-bit microcontroller family.

Precision32 Integrated Development Environment

Silicon Labs’ Eclipse-based integrated development environment (IDE) includes a full compiler, debugger and an online dashboard for application-critical information such as a software library with example code, data sheets, schematics, PCB footprints, app notes, active version tracking and automatic updates. These tools are available for free, with no code size or time limitations.

Precision32 AppBuilder Rapid Prototyping Utility

A centerpiece of the IDE is Silicon Labs’ Precision32™ GUI-based AppBuilder rapid prototyping utility, which enables developers to quickly and graphically select peripheral mix and properties, set up clocking modes, customize pinouts and generate source code – all without having to read a data sheet or learn register settings. Sophisticated mode management validates peripheral properties and pin assignments, and provides real-time feedback when conflicts are detected.
