STMicroelectronics X-CUBE-IOTA1 2.0 expansion software

In line with the Chrysalis upgrades to the IOTA Foundation’s distributed ledger technology (DLT) and infrastructure, STMicroelectronics has announced an updated version of its X-CUBE-IOTA1 expansion software package, including integrated IOTA C library, for the STM32Cube microcontroller software development ecosystem. The IOTA DLT is a decentralised secure database that protects against data tampering, and the Chrysalis protocol upgrade is said to be 60% more energy efficient than IOTA’s original implementation.

STM32Cube integrates low-level and middleware software in one library together with a configuration tool to generate initialisation code for embedded applications running on any MCU from the STM32 microcontroller family. With more than 100 expansion packages, STM32Cube is a dynamic development resource that welcomes additional software components to enable specific application use cases. The updated X-CUBE-IOTA1, which includes IOTA-specific middleware and sample implementations, lets developers benefit from the efficient performance and high feature integration of STM32 MCUs to build smart, connected transaction-handling devices leveraging the latest Chrysalis upgrades to the IOTA DLT.

The updated software runs on the B-L4S5I-IOT01A Discovery kit for IoT node, which features an STM32L4+ MCU and connects to the internet through the integrated Wi-Fi interface. The package relies on the optimised and robust security algorithms provided by the STM32 Cryptolib, and includes middleware libraries and a complete driver to access motion and environmental sensors on board.
