ModusToolbox™ software is a modern, extensible development environment supporting a wide range of Infineon microcontroller devices. It provides a flexible set of tools and a diverse, high-quality collection of application-focused software. These include configuration tools, low-level drivers, libraries, and operating system support, most of which are compatible with Linux, macOS, and Windows-hosted environments.
This page helps you identify and find the ModusToolbox™ resources available. These resources are grouped in the following top-level categories:
- Tools
- Code examples (link to separate page)
- Board support packages
- Libraries
- Training material (link to separate page)
The ModusToolbox™ tools package installer (https://www.infineon.com/cms/en/design-support/tools/sdk/modustoolbox-software) provides various multi-platform development tools to help you work in your preferred flow. The installer includes a make-based build system, Eclipse IDE, configurators, stand-alone project creator and library manager, as well as support for using other IDEs, generating code, compiling, programming, and debugging. Refer to the ModusToolbox™ tools package user guide for complete details.
Some tools are available separately on GitHub, including:
| Tool | Description | Docs |
|---|---|---|
| Firmware-loader | A command-line tool to update KitProg low-level program/debug communication firmware on our kits. Installed with ModusToolbox™ tools package, newer version may be available on GitHub. | readme |
| "Secure Boot" SDK | This SDK includes all required libraries, tools, and sample code to provision and develop applications for PSoC™ 64 "Secure Boot" MCUs. | User guide |
For any ModusToolbox™ application, you must specify a Board Support Package (BSP), which defines basic device features and capabilities. The BSP is a central feature of ModusToolbox™ software. The BSP specifies several critical items for the application, including:
- hardware configuration files for the device (for example, design.modus)
- startup code and linker files for the device
- other libraries that are required to support a kit
BSPs are aligned with our kits; they provide files for basic device functionality. A BSP typically has a design.modus file that configures clocks and other board-specific capabilities. That file is used by the ModusToolbox™ configurators. A BSP also includes the required device support code for the device on the board. You can modify the configuration to suit your application.
We release BSPs independently of ModusToolbox™ software as a whole. This search link finds all currently available BSPs on the GitHub site.
The search results include links to each repository, named TARGET_kitnumber. For example, you will find links to repositories like TARGET_CY8CPROTO-062-4343W. Each repository provides links to relevant documentation. The following links use this BSP as an example. Each BSP has its own documentation.
The information provided varies, but typically includes one or more of:
- an API reference for the BSP
- the BSP overview
- a link to the associated kit page with kit-specific documentation
A BSP is specific to a board and the device on that board. For custom development, you can create or modify a BSP for your device. See the ModusToolbox™ tools package user guide chapter on BSPs for how they work and how to create your own for a custom board.
There are many other parts of ModusToolbox™ software that are provided as libraries. In general, you should not need to use these libraries directly. When you create a ModusToolbox™ application, the system downloads all the libraries your application needs to take full advantage of the various features of our devices. A ModusToolbox™ application can use different libraries based on the Active BSP. If you wish to add various libraries to your application, use the Library Manager tool.
The following tables provide brief descriptions about the libraries available and links to the various repos. Refer to the ModusToolbox™ run-time software reference guide for more details about how these libraries are used in the ModusToolbox™ ecosystem.
