A Complete No-Cost Commercial Development Environment

You can waste months porting an OS and developing the board support package, basic support utilities and communication protocol stacks — even before writing the first line of traditional C- code. Using “free” software stacks can lead you down of path with minimal support and a hodgepodge of building blocks constant requiring attention. Serious gives you a complete, no-cost, commercially supported development environment, including tools and software, to enable you to focus on your communications and control software, not the infrastructure. We call it Leveraged Embedded.

Full Commercial Dev Tools

Every SCM Development Kit comes with an unlocked, single seat commercial license to Segger Embedded Studio, enabling powerful cross-platform C development and debugging for your SCM projects. All Serious ARM-based SCM example projects come pre-engineered out-of-the-box for Segger Embedded Studio.

SHIPWare – A Complete Firmware Platform for Comms/Control App Development

Every SCM also comes with Serious SHIPWare – a starting set of code and firmware on which you can build powerful control and communications applications, leveraging all the features of your module. SHIPWare complete, commercially supported software including:

Segger OS and Stacks
Serious frameworks and infrastructure, including the SHIPv5 Boot System with firmware update and version management
Drivers and high level abstractions for on-board peripherals, including UART, SPI, I2C, WiFi, Ethernet, FLASH storage, and more

From Segger, the following no-cost, pre-licensed, pre-ported and fully supported linkable object libraries are included:

Segger embOS kernel, pre-ported and optimized for the platform
Segger emFile file system, including FAT and embedded file system support with journaling, and all the necessary drivers pre-integrated for the platform
Segger emUSB-Device USB device/host stacks with various classes, and pre-integrated for the peripherals
Segger emTCP/IP and TLS/SSL security stacks (including DHCP, web server, ftp, and more), pre-integrated with the WiFi and Ethernet peripherals
Segger MQTT and CoAP stacks for IoT data connectivity
Segger emCrypt, the foundational NIST-validated security you need for IoT and device connectivity

This OS and stack implementation is fully supported by Serious and is production-licensed for one copy per Serious module purchased – there are no additional required fees or licensing to use the Segger object software with the SCM. Source code and Segger-direct support is available as an upgrade from Segger with a discount for Serious customers.

In addition to these ingredients, SHIPWare includes numerous application level frameworks, drivers, and example code for developing a communicating and controlling application, including heap and buffer management, the SHIPBridge device and host protocol stacks for communicating with the HMI. This software is provided in source code format and is fully supported by the Serious team.

Production Line and Application Installation Tools

Out of the box, the SCM also includes the SHIPv5 Boot System, including pre-installed boot-strap and boot-loader applications enabling you to install and commission your custom embedded application on the board on the production line using the no-cost SHIPCrane tools or even over-the-air/wire.

SCM Development Engagement Model

There is no cost or royalty for the out-of-the-box software/firmware for Serious Comms/Control Modules (SCMs). However, getting access to this software and firmware for initial development with SCMs requires a one-time “kickstart” engagement with our Services team to ensure a smooth first project experience. First-time access to SCM dev kits and downloads is predicated on having this engagement in place. Once you’ve been through this initial process, ongoing support (including new revisions of firmware and access to new SCMs) is available at a nominal charge through an annual maintenance and support contract. Contact Serious for details.
