Machine learning models + IoT data = a smarter world

With the IoT market set to triple in size by 2020, and massive increases in computing power on small devices, the intersection of IoT and machine learning is a trend that all developers should pay attention to. This talk will cover three core use cases, including: how to manage sourcing data from IoT devices to drive machine-learned models; how to deploy and use trained models on mobile devices; and how to do on-device training with a Raspberry Pi computer.

System Workbench for STM32 - a Free IDE for STM32 Microcontroller

The System Workbench toolchain, called SW4STM32, is a free multi-OS software development environment based on Eclipse, which supports the full range of STM32 microcontrollers and associated boards.

The SW4STM32 toolchain may be obtained from the website www.openstm32.org, which includes forums, blogs, and trainings for technical support. Once registered to this site, users will get installation instructions at the Documentation > System Workbench page to proceed with the download of the free toolchain.

The System Workbench toolchain and its collaborative website have been built by AC6, a service company providing training and consultancy on embedded systems.

This product is supplied by a third party not affiliated to ST. For the latest information on the specification, refer to the third party’s website: www.ac6.fr.

Key Features

• Comprehensive support for STM32 microcontrollers, STM32 Nucleo boards, Discovery kits and Evaluation boards, as well as STM32 firmware (Standard Peripheral library or STM32Cube HAL)
• GCC C/C++ compiler
• GDB-based debugger
• Eclipse IDE with team-work management
• Compatible with Eclipse plug-ins
• ST-LINK support
• No code size limit
• Multiple OS support: Windows® , Linux and OS X®

Install System Workbench for STM32 on Ubuntu GNOME 16.04 (run on VirtualBox)

Before install System Workbench for STM32, java is needed to be installed. Enter the command:
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer

To download System Workbench for STM32, visit: http://www.openstm32.org/Installing+System+Workbench+for+STM32+with+installer.

Fow Linux 64-bit, it is install_sw4stm32_linux_64bits-v1.8.run currently.

Accessing OpenSTM32.org is free, but you need to be logged in to have access to some parts of the site, like the System Workbench for STM32 documentation and download instructions.

For Ubuntu 64-bit, download the external tools with command:
$ sudo apt-get install libc6:i386 lib32ncurses5

To launch the installer in GUI mode, gksudo must be installed:
$ sudo apt-get install gksu

Then run the downloaded installer (install_sw4stm32_linux_64bits-v1.8.run); switch to the download folder, make it executable, run it and follow the steps:

$ ./install_sw4stm32_linux_64bits-v1.8.run

Check for update after finished.

ST-Link/V2-1 driver on Linux

The ST-Link/V2-1 is supported by libusb but the device has to be named with a udev rule.

Download the following tarball which contains 49-stlinkv2.rules
