The communication system The Arduino Uno Q features a specialized communication method designed to handle data exchange between the MPU and the MCU. This system is based on RPC (Remote Procedure Call). In this post, we will explore the architecture, the protocol, and a hands-on example of how to send and receive commands. We'll even dive into a logic analyzer capture to see exactly how it works under the hood. Before proceeding with this post, I strongly recommend reading my previous review of the Arduino Uno Q: https://myembeddedstuff.com/arduino-uno-q-new-paradigm-review RPC Description Communication is based on RPC (Remote Procedure Call). This system operates like a sort of Router, hosted on the MPU as a service called Arduino-Router. It is responsible for creating and managing a connection table. This…
