One year ago i was annoyed by the missing failsafe feature of the stock firmware of my VD5M receiver.Stm32 uart receive
My brushed micro quad nearly flow away because of that. This was when i started to look out for alternatives. There were some diy receivers using atmega processors and code from midelic, a user of rcgroups.
They did not quite fit my needs, the cheap cc modules from china had some rx issues and i never got them to work percent reliable. This is when i started to write my own firmware for FrSky gear….
OpenSky Feeder for Dump1090 (Raspberry Pi-based)
I started with a vd5m. I gathered some information about the used chipset a ccgot a cc-debugger for it and started blinking leds.
That was quite easy once you get used to the sdcc compiler. After tracking all traces and writing down a pinout i started to work on the receiver code. When i got it working i started adding more features such as SBUS output. After some modifications, introducing a hardware abstraction layer and some testing i finally got my code to support both targets.
A new feature was added as well, the code supports incoming serial hub telemetry — you can hook up that port to your flight controller and receive various telemetry data on your tx. Of course it also runs OpenSky. This is my approach of building a tiny flight controller with an integrated uSKY receiver. My code is not based on any FrSky code, it was written from scratch with some inspiration from midelics atmega code.
I am not affiliated with FrSky in any way. This is just my personal hobby project. As written before i did not only implement the features of the original receivers but added or enhanced some features:. This is for educational use only, bad things could happen if you run this on a real vehicle.
Using this code will probably void its FCC compliance and might void transmission laws depending on your country! Thanks to midelic from rcgroups.
They are cc based and there are a lot of bricked out there. Ask my how I know? It is just a matter of tracing the pinout and setting the proper defines in the config file.
It should work out of the box. The tinyFISH bf firmware includes all settings. You can load the defaults. You can always connect a receiver to the UART3 pads next to the usb port. I was wondering how complicated it would be to add support for the D8R-II receiver?Upgrade issue: when updating from v2.
Either reboot your device or use sudo systemctl restart opensky-feeder after installation. The setup just takes 5 minutes. Check out this page to install the feeder on a different architecture.

Next, execute the following two commands for the second command, you might have to enter the password again. After that, you will be prompted some questions about your receiver setup. If you have an OpenSky accountyou can also supply your OpenSky username.
If you configure your receiver a second time i. If you leave this field blank, you'll be assigned a new serial number automatically. Don't worry, the negative serial number is alright.
Known issue After the setup is done, the feeder is started automatically and starts feeding to the OpenSky network. It is furthermore started every time the raspberry pi is booted. If you want to update the feeder, you can execute the previous steps again. You can also refer to the Changelog to see if there are any updates. Your configuration will be retained, so you won't be asked for your location again. You can also use apt to keep the feeder up to date, as described here. If you want to reconfigure the feeder e.

Historically we had 3 branches named developrelease and production. Developers would work on changes in a branch created from develop.Body measurements
Once the work was done, the branch would be merged back in to develop. Then a tag would be created from the production branch and the tag would get deployed.
Hotfixes and other small changes would sometimes be branched and merged directly to the production branch. Over the years we invested heavily in our automated test and deploy processes. The goal was to make the processes very fast, stable and easy to rollback if something goes sideways. A developer should be able to push up a change and get feedback from the automated test suite in minutes or less. It used to take up to an hour to get feedback from the tests because the tests all ran serially.Parallel lines and transversal practice set 2 3
We built a tool internally called PHPChunkit that allows you to run your tests in parallel chunks across multiple servers. On top of the speed issues, the coverage was not that great, so every change required lots of manual QA before it could go to production.
The need to manually QA everything meant it was very costly to test and deploy individual changes in isolation. This is one of the reasons the above process to batch things up and test and deploy them together every 2 weeks was used. We also improved the speed to deploy to production. The process used to be a series of automated steps that were executed by a human and would take up to an hour sometimes.
Once this process was fully streamlined, optimized and automated we were able take a change to production in less than 10 minutes. This is including running the full test suite before going to production.
There was a bit of a cultural change that happened through all of this too. Due to limited manual testing resources, we mandated that developers must include unit and functional tests with their changes. If they fix a bug, the first commit should be a test demonstrating the failure and the 2nd commit should fix it. We got rid of the develop and release branches and all changes get branched off of production. All changes are tested and deployed in isolation. Branches are usually short lived and are tied to a single developers work.
We now deploy an average of 5 times per day and have deployed as many as 20 times in a single day. Our overall throughput went up, we have less issues in production and our fear of change decreased.

Additionally: Do not blame me if you brick your RX during the flash upgrade. Hook this up to a 3.Cirrus logic cs4208 driver windows 10
There are probably thousands of bugs. Please report any bugs! Alternatively, you can use a raspberry pi to flash. It is handy to mount a 5pin Molex Picoblade connector to the 5pin ISP connection on the side of the vd5m.
This way it is easy to upgrade firmware. In order to enter the bootloader temporarily short circuit the Jumperpad R19 to enter the boot loader. The D4R-ii has a signal inverter on board, thus the serial lines are inverted. Connect an inverted serial cable to the 4pin connector FTDI devices can be configured to invert rx and tx using mprog!
