UAVCAN for Hobbyists: Inaugural Release

[OlliW]

Hey Folks

there are already two UAVCAN for Hobbyists threads in this mailing list, full of questions which Pavel patiently answered.

This third one here is about announcing that the project has reached some sort of practical usefulness: I have uploaded release v0.19, and created some info:
* Binaries for the uc4h slcan adapter and uc4h gps-mag node can be found here: https://github.com/olliw42/uavcan4hobbyists/
* Some info on the project and build schemes are here: http://www.olliw.eu/2017/uavcan-for-hobbyists/

Since this is intended for hobbyists, this additional info: The uc4h SLCAN adapter can be build for as little as $4.71, and the uc4h GPS-magnetometer node for as little as $3.70 (exclusive GPS+compass module), using widely available cheap standard modules . However, as part of the project I've also designed some PCBs, two-layered SMD of 0604 size, which are simple enough to be build but are probably somewhat more useful.

Pictures and schemes you find on the above web page, and some test results in a ardupilot.discuss thread.

Pavel, thank you soo much!

Cheers, Olli

Olli - Awesome work! I was wondering if you knew if there was anyone looking to implement any of the UAVCAN libraries in Arduino? I know some of the various devices like the Teensy or the ESP32 or ESP8266 have CANBUS capabilities, and with a transceiver could be made to interface with a CAN. I'm thinking of a generic use case for sensing and control. Someone could use the library to create their own UAVCAN devices.   

Keep up the good work, I hope support builds for UV4H!

Dear Olli,

thank you so much for the UAVCAN for hobbyist examples you posted online.
We are currently working on utilzing UAVCAN for a rocketry / sattelite project and would like to use STM32F103s for node on the bus...

Would it be possible to obtain a copy of the source code, that you run on the STM32 for for example the UC4H GPS-Magnetometer Node,
since we are trying to get started with implementing a publisher-sensor-node for something simpler (BME280 or similar...) ??

We also consider loading the STM32 with ChibiOS, but want to see if we could benefit from understanding and trying out a
bare-metall implementation of an UAVCAN sensor node (I'm assuming your STM32-version of the nodes are bare-metall and do not use an OS...)..

Thanks!

Kind regards
Niels Göran
