Pi Pico Learns Morse Code

https://invidious.privacyredirect.com/watch?v=rBRf3QOt4wc

When [101 Things] didn’t want to copy Morse code, he decided to build a Pi Pico system to read it for him. On the face of it, this doesn’t seem particularly hard, until you look at the practical considerations. With perfectly timed dots and dashes, it would be trivial. But in real life, you get an audio signal. It has been mangled and mixed with noise and interference as it travels through the air. Then there’s the human on the other end who will rarely send at a constant speed with no errors.

Once you consider that, this becomes quite the...

Cangaroo open-source CAN bus analyzer supports SocketCAN and CAN-FD on Linux

Cangaroo is an open-source CAN bus analyzer for Linux systems used in automotive, robotics, and industrial environments. The desktop application focuses on real-time capture, decoding, and analysis of CAN and CAN-FD traffic, with native integration into the Linux SocketCAN stack.

DeepComputing has opened an Early Access Program for the DC-ROMA RISC-V Mainboard III. This hardware is a modular internal component designed to fit the Framework Laptop 13 chassis. It allows users to transition the modular laptop to a RISC-V architecture while utilizing the existing 2.2K display and shell. The board features the SpacemiT K3 SoC, […]

Making self hosted web user interface for BME280 temperature, humidity and pressure sensor for ESP32-POE, ESP32-C6-DevKit-Lipo and ESP32-C3-Devkit-Lipo with ESPUI

When building an ESP32 project controlled through a self-hosted web interface, one of the most boring and repetitive tasks is creating the user interface. Several projects aim to simplify this process. One popular option is ESP-DASH, but the open version is quite limited, and the Pro version—required for practical use—is paid. Fortunately, there are several […]

PicoClaw ultra-lightweight personal AI Assistant runs on just 10MB of RAM

PicoClaw is an ultra-lightweight personal AI Assistant designed to work on less than 10 MB RAM and suitable for resource-constrained embedded boards such as the Sipeed LicheeRV Nano SBC going for around $15 and powered by a SOPHGO SG2002 RISC-V SoC with 256MB on-chip DDR3. I keep reading news about the OpenClaw personal AI assistant, after first finding out about it when the Cubie A7S SBC was launched. OpenClaw (previously ClawdBot) clears your inbox, sends emails, manages your calendar, and checks you in for flights from WhatsApp, Telegram, or any chat app. It’s been shown to run a range of...

Black Sesame Technologies Wudang C1200 “cross-domain” automotive SoCs feature up to 10x Cortex-A78AE cores

I found two interesting automotive SoCs in the Linux 6.19 changelog: Renesas R-Car X5H 16-/32-core Cortex-A720AE SoC and Black Sesame Technologies’ “Wudang” C1200 8-/10-core Cortex-A78AE processor family. While announced in 2024, there’s still no product page for the Renesas chip. So today, I’ll focus on the Wudang C1200 family. They are designed to be automotive-grade “cross-domain computing platforms” capable of handling multiple functions such as in-cabin sensing systems (e.g., driver attention monitoring), infotainment, auto-parking systems, safety information, autonomous driving, and more. Wudang C1296 10-core SoC Wudang C1296 specifications: CPU 10x Arm Cortex-A78AE automotive-grade cores Dual-Core Lockstep (DCLS) supported, ASIL-D compliance...

Streamlining Your Digital Dash: How the Bridgetek EVE Controller Empowers STM32 Designs

For many engineers, the leap from basic character displays to a full-color Graphical User
Interface (GUI) feels like a daunting hardware hurdle. When the FS-3 Formula SAE team began designing their 2025 car, they hit a common roadblock:
How to drive a high-resolution 5” display without overhauling their existing STM32-based architecture.

The solution wasn’t just in the pixels—it was in the silicon. By choosing the CFA800480E3-050SN, they utilized the integrated Bridgetek (EVE) display controller.

Standard “dumb” displays require the host microcontroller (MCU) to handle every pixel
calculation, frame buffering, and refresh cycle. For an STM32 already busy managing vehicle
telemetry and...
