  1. Overview

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 Suite

Download the free Precision32 Development Suite, which includes all of the following components:

Components

 Precision32 Integrated Development Environment (IDE)

 Precision32 AppBuilder Rapid Prototyping Utility

 "Power-Aware" System Optimization Tools

 Si32 SDK (HAL, Software Libraries and Development Kit Utilities)

 Precision32 SDK Release Notes

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.



"Power Aware" System Optimization Tools

The Precision32 Eclipse-based IDE and AppBuilder software include new, first-of-a-kind capabilities for estimating power consumption and providing configuration guidance for developers to achieve the lowest system power:Power Estimator provides a graphical estimate of the total supply current of the MCU. Designers can see which peripherals consume the most power in the system and configuration changes are updated automatically in the output. Each mode, active and sleep, has its own Power Estimator output.Power Tips provides software configuration guidance that helps developers minimize current consumption. This feature is available within AppBuilder allowing developers the ability to see power consumption while configuring the MCU.



Extensive Software Library

Silicon Labs' Precision32 microcontroller library provides building blocks for creating new stacks, allowing developers to focus on their end application instead of spending time on MCU specific details. Modular components can be reused and easily re-arranged.

Made with simplicity in mind, the Si32Library easily hooks into the main application via function calls. The Si32Library is comprised of flexible, scalable and portable source modules enabling core functionality for error handling, debug logging, memory allocation, buffer management, data collections, data transfers, event notification, multitasking, USB, tool chain portability, RTOS compatibility, and more. Portable objects can connect directly to Silicon Labs HAL (hardware access layer), which are easily configured using AppBuilder, a free GUI-based initialization tool.

Get your application up and running quickly:

  • Configure the hardware using AppBuilder
  • Configure the library components
  • Examples:
    • Si32BufferObject
    • Si32QueueObject
    • Si32PortalObject
    • Si32USBDeviceObject
    • Si32RunloopObject
    • Si32PseduoThreadObject
  • Add application specific code

The Si32Library is delivered as source code as part of the Precision32 Development Environment installation. Customers can modify and adapt it to tune performance and memory as required by their application. A simple object-based model allows for reuse and modularity without the added complexity of C++.

System Requirements

The Precision32 Development Suite requires one of the following operating systems:

  • Windows XP (SP2 or newer)
  • Windows Vista
  • Windows 7
