Arduino Uno Q: The Truth About its Boot-Up Performance

I’d seen a lot of conflicting info on various forums about the Arduino Uno Q's boot time. I decided to stop guessing and test it myself using my own setup to see exactly how long it takes from power-on until the first instruction of a sketch actually executes.In this article, I analyze the startup performance of the Arduino Uno Q boot. I’ll be measuring exactly how long it takes for the MCU sketch and the MPU Python script to execute from the moment the board receives power.Unlike theoretical analyses, I am using external signals and a logic analyzer to pinpoint when each processor begins execution and determine whether they start simultaneously.Specifically, I aim to answer: Does the MCU sketch start automatically? How long does…

Arduino Uno Q Communication: A Deep Dive into RPC

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…
