Top 23 C Firmware Projects

  • Tasmota

    Project mention: Trying to flash or replace and EcoPlug 8266, I have questions. | reddit.com/r/esp8266 | 2022-08-11

    You should look at the Tasmota website. They have a good guide about flashing the software and I found a template for the other switch you mentioned. If the template isn't right you might have to play around to find out which gpio pin does what but that is also explained in their documentation. It won't be easy though.

    Project mention: Toit – A Language Designed for Microcontrollers | news.ycombinator.com | 2022-06-08

    As long as Toit is licensed under the GNU Lesser General Public License v2.1, I am unlikely to consider using it. By contrast, MicroPython is licensed under the MIT License (MIT).

    As others have noted, Toit seems like a bad name. I suppose non-French speakers will tend to inadvertently mispronounce Toit.

    Getting traction is hard. In my opinion, having a restrictive license and a bad name make it less likely Toit will gain traction. Finally, Toit licensing reminds me of Mongoose OS https://github.com/cesanta/mongoose-os#mongoose-os---an-iot-....

    Project mention: Does pwnagotchi work on zero 2 | reddit.com/r/pwnagotchi | 2022-03-24

    I was able to get pwnagotchi to work on the pizerow2 with AI mode. I basically used DrSchottky's image, then ran https://github.com/isthisausername2/pwnagotchi_rpi_zero_2_fix, then compiled the nexmon drivers on the device (https://github.com/seemoo-lab/nexmon).

    Project mention: IP cam not communicating when connected to main router | reddit.com/r/HomeNetworking | 2022-06-04

    I have a raspberry pi running Shinobi as a NVR system for my house. I have IP cams that have been firmware unlocked (Yi Hack), my issue is when they are connected to my access point in the front of the house I can query them with no problem and access the webUI, pull the RTSP stream etc, once I change the wifi to my main modem they basically go cold. I can see them on angry IP scanner as blue (they are there and connected though not responding to query). I'm unsure where to start, port forwarding seems to just block port 8080 and shut out my net when I'm trying to access the Pi.

  • OpenSteamController

    Steam Controller reverse engineering and customization project.

    Project mention: Does the steam controller work with the 8bitdo wireless USB adapter? | reddit.com/r/SteamController | 2022-08-07

    However, there's an open source project that enables the controller to function on the Switch through cable, basically flashing the controller's firmware so it functions as a generic wired USB controller compatible with the Switch. You can check a video here. I'm not sure if the bluetooth angle would be able to be rewritten so it mimics a Switch Pro Controller or a generic Xinput controller so it can be synced to the 8bitdo dongle tho.
