This workshop marks the conclusion of our trilogy on the serial interface, building upon the insights shared in the last two Embedded Online Conferences. In this session, we will explore an advanced Direct Memory Access (DMA) technique that transforms the traditional character-based serial interface into a variable-length, packet-oriented one, similar to Ethernet. This powerful approach opens up new possibilities for reducing the complexity of software required for command handling and file transfers.

We will start by examining the theoretical foundations of this DMA technique, discussing its implementation for managing data packets of varying lengths. Following this, we will demonstrate practical applications through live coding on an STM32 Nucleo board. You will witness firsthand how this transformation simplifies the development of software for command handling and file transfer. By the end of the workshop, you will have a clear understanding of how to apply these concepts to your own projects to enhance the robustness and efficiency of your embedded systems.

Join us for this comprehensive session, where theory meets practice, and elevate your understanding of serial interfaces to the next level.
