#Embedded

Open-source ESP32-S3 firmware, browser tools, recipes, documentation and companion hardware for exploring wired buses, USB adapters, wireless protocols, firmware workflows and embedded devices.

It's time for another technical blog post about async Rust on embedded. This time we're going to pitch Embassy/Rust against FreeRTOS/C on an STM32F446 microcontroller.

A comprehensive guide on using the Rust programming language with Espressif SoCs and modules

Hey everyone, I am working on a project using a Raspberry Pi to communicate with a PGA112 EVM (Programmable Gain Amplifier) over SPI. I am using an Analog Discovery 2 logic analyzer to check the signals.…

I’ve put together a basic working prototype of a project for a client using those two components and the most basic connections to read NFC cards.…

Project: microcontroller : ESP32-S3 1.47inch IPS Touch Display Development Board, 172x320 Resolution, 262K Display Color, Support 2.4GHz W-i-F-i 6/BLE 5, 240MHz LX7 Dual-core Processor, Sensor: MAX30102 blood oxygen wrist heart rate and pulse detection…

A small C89-compatible fixed-size object pool for cases where you want predictable performance and avoid repeated malloc/free calls. It preallocates a block of objects and reuses them in constant time (O(1)) using a simple push/pop style API.…

I have been working on a project that uses a TI BQ25713 power / battery charge controller and supports USB PD. The device operates well and does everything I need with minimal firmware configuration, thanks to HW pin strapping, happy with everything the…

Hey i am a student persuing ECE , i have been working with embedded systems since a year or two now . I have also shipped products both for private and govt bodies .…

TL;DR: I'm recreating the Serial Loopback project from Make: AVR Programming on an ATmega328p. The UART echo works fine, but the LEDs on PORTB do not display the ASCII value of the ASCII received character.…

I recently developed a PCB around an AT32F421 MCU and regret it as to obviously not having the same kind of support as STM32. I am new to AT32/STM32 as I have only really used ESP32 based systems.…

I've set my sights on creating an RTOS system running on STM32N6570-DK with some kind of FMCW radar module (any recommendations?) for distance and velocity of a flying RC toy.…

Hi everyone, My MSI PRO B660M-A DDR4 motherboard got bricked after a power cut during a BIOS update. Local repair technicians are asking around 1/3 the price of the motherboard just to fix it, so I'm deciding to try repairing it myself.…

- 3 individual tracking ids: showing distance - Heat Trail - Heading indicator - Correct distances according to spec. sheet This library https://github.com/javier-fg/Arduino\_RD-03D Was very helpful.…

Hello all! I wanted to share my first ever embedded project. Though it really only scratched the surface it opened my eyes to the vastness of the world of embedded engineering.…

Been coding C for 8 years with image sensors, previous automotive engineer before that doing Simulink. I impressed through take home coding, 2 technicals, and just finished my onsite interviews this week.…

Hi everyone, I created an open-source domain specific language and composition engine called Firmion. The goal is to make firmware image creation more obvious and maintainable.…

To start off with, I apologize if there is a post on this already. Personally, I will say I have scoured this community and the internet regarding my "dilemma" but the answer changes from person to person so I decided to bite the bullet and make a…

Hey everyone, I’m a 2nd-year Electronics Engineering student and a beginner in open-source contributions. I want to start contributing to open-source electronics projects to learn, gain experience, and improve my skills.…
