Sending messages to a screen in serial console is the simplest and most common way to debug embedded programs. In Arduino projects, using Serial.print() is a standard debugging technique.

This document records the complete process of bringing up and debugging a custom UART-based LiDAR sensor on a ROS2 (Humble) robot platform. The LiDAR streams raw distance frames via /dev/ttyUSB0, ...

RP2350B development board Bells&Whistles combines a Raspberry Pi RP2350B target with an onboard RP2040-based debugger, HDMI output, and a microSD card slot. The result is a compact open-hardware board ...

Abstract: This paper presents a novel UART-based debugging interface for resource-constrained RISC-V soft-core implementations on FPGAs. Unlike traditional JTAG-based approaches that require dedicated ...
