Top 23 C Firmware Projects

  • Tasmota

    Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at

    • Project mention: Printing emails based on Message Filters, does not seem possible | /r/Thunderbird | 2023-12-02

    All of my office devices are connected to Sonoff S31 smart plugs, flashed with Tasmota on their own locked-down VLAN, and can be controlled via voice, Alexa, Tasker automation on my Android, NFC tags at my office door and various scripts triggered via my StreamDeck (on Linux). This all works fantastic, and I can turn on or off my devices, including my printer, when I start or end my day at work.

  • unleashed-firmware

    Flipper Zero Unleashed Firmware

    • Project mention: Flipper Zero: Multi-Tool Device for Geeks | news.ycombinator.com | 2024-01-21

    I got one not too long after the official launch and I've used it a decent amount (granted I am in cybersecurity and have a more real-world use cases then the average person). My favorite use case is the IR remote since phones no longer have IR blasters. It's saved me twice so far in having to buy/find a remote for something.

    One thing people don't realize is that the custom firmware [0] that you can run allows you to receive and transmit on a wide range of frequencies under 1Ghz. Lots of things use that range (garage doors, gates, fan remotes, etc.) and are not very secure. I think that this will be a time looked back on where it's possible to interact with those devices without having to buy a custom PCB transmitter or somewhat expensive and complex SDR.

  • flipperzero-firmware

    Flipper Zero firmware source code

  • nodemcu-firmware

    Lua based interactive firmware for ESP8266, ESP8285 and ESP32

  • IronOS

    Open Source Soldering Iron firmware

    • Project mention: Accessing the Pinecil UART with Picoprobe | news.ycombinator.com | 2024-01-30

    So apparently the Pinecil is a BLE-enabled soldering iron with a 108 MHz RISC-V processor running a custom real-time operating system [0]. The author wanted to access the UART logs, so they repurposed a Raspberry Pi Pico (a dual-core microcontroller system running a real-time OS) for the task.

    That's a staggering amount of hardware, sortware and computing power devoted to decoding one of the simplest and oldest serial protocols from a device whose sole purpose is to essentially melt tin. Maybe I'm out of touch, but I think I'll stick to my thermostat-controlled Weller soldering station and FTDI UART converters. I apologize if this post comes across as snarky, my point is that these are solved problems and have been for half a century.

  • edk2

    EDK II

    • Project mention: Future of 32-bit platform support in FreeBSD | news.ycombinator.com | 2024-02-20

    For the modern server/desktop and even laptop, that's also no bad thing. It is somewhat ridiculous that UEFI bioses, internally, still boot in 16-bit real mode and have to do all the steps your bios bootloader used to do to set up a 64-bit environment ready to go: https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a...

    Why not just start the CPU in "long mode", which is what everyone is using it for, in the first place?

    These newer ARM processors support 32-bit code at EL0 only (userspace). That seems like a reasonable approach for x86 as well and the freebsd announcement has this to say:

    > There is currently no plan to remove support for 32-bit binaries on 64-bit kernels.

    So for the moment, you can run 32-bit applications just fine.
