 Hello and welcome to the presentation of the STM32C0 large ecosystem that contributes to simplify the implementation of these microcontrollers. The STM32 eval boards have been designed as a complete demonstrator and development platform for the STM32 MCUs and MPUs. The evaluation boards can be considered as a reference designed for application development. Two types of STM32C0 boards are available for different users depending on the targeted applications. STM32C0 nuclear boards enable quick and flexible prototyping. STM32C0 discovery kits target more creative demos. STM32 nuclear boards can easily be extended with a large number of specialized application hardware, add-ons, thanks to Arduino Uno RAV3 and ST Morpho connectors. The STM32Cube ecosystem is a software solution for STM32 microcontrollers and microprocessors created for designers interested in a free comprehensive development environment and for users looking to integrate STM32 software in their existing IDE, such as Kyle or IAR IDEs. All these tools have been tuned to support the new STM32C0 series features. The Azure Arto Suite has been added to STM32Cube to complement the existing offer and to deliver the highest quality of service and quick time to design with a free of charge production license for STM32 users. It includes the ThreadX ArtoS, the FileX file system with wear labeling and fall tolerant modules to support NAND and NOR flash memories, the industrial grade NetX TCPIP stack optimized for performance and coming with many IoT protocols including security support and the optimized USB X device and host USB stack coming with many classes. STM32Cube MX is a graphical tool that allows a very easy configuration of STM32 microcontrollers as well as the generation of the corresponding initialization C code for the ARM Cortex M0 plus core through a step-by-step process. Through an intuitive user interface, the user first selects the MCU or the board and then configures the pinout, the clock tree, the peripherals and the software components. STM32Cube IDE is an all-in-one multi-hours development tool which is part of the STM32Cube software ecosystem. STM32Cube IDE is an advanced CC++ development platform with peripheral configuration, code generation, code compilation and debug features for STM32 microcontrollers. It's based on the Eclipse CDT framework and GCC tool chain for the development and GDB for the debugging. It allows the integration of the hundreds of existing plugins that complete the features of the Eclipse IDE. This slide summarizes the tools involved in the various development steps, configuring the MCU through STM32Cube MX and generating the project for the following IDE's STM32Cube IDE, IAR or KYLE Developing and debugging the application software through STM32Cube IDE, IAR or KYLE Programming the STM32 internal memories thanks to STM32Cube programmer Monitoring the execution by using STM32Cube monitor which helps to fine-tune and diagnose STM32 applications at runtime by reading and visualizing their variables in real-time. Thank you for attending this presentation.
