CoAP on micropython?

Is there any CoAP implementation for micropython available?

I found https://github.com/chrysn/aiocoap which is for python 3.4 but I dont know if it would run on micropython.

I am looking into making available sensordata to IoT servers over CoAP from micropython boards.

Thank you.

Porting Mirocpython to Risc V ?

We got a small FPGA reserarch project funded. We consider running Micropython on a Risc V core on an FPGA. Having micropython as an interpreter would make things easy on the higher levels. We do our own Lattice based FPGA board with Flash and Memory and interfaces, so we are flexible on that side. I...

Re: Is 32kByte enough for micropyhton?

So it might be absolutely doable to run 100.000 instances of micropython (e.g. to simulate neurons) on this massively connected machine of 100.000 cores with 32kbyte of RAM each. http://apt.cs.manchester.ac.uk/projects/SpiNNaker/project/ The next machine which will have 1 mio cores (which is current...

Is 32kByte enough for micropyhton?

Some cores like Arm M0 do only have 32kByte RAM.

Did someone already port Micropython to any 32kByte Core?

Thank you

Re: Pyboard control system design

There is a project evaluating the use of an FPGA for handling the control loops. The FPGA could be programmed/configured by the microcontroller (therefore the reverse engineering of the bitstream) the microcontroller would then do only the high level stuff. even he would be able to go sleeping for s...

Re: Pyboard control system design

You might want to look at https://www.indiegogo.com/projects/raspicommplus-all-in-one-raspberry-pi-extension/ They run a naked binary on the M0 core in the extender board which is connected over SPI to the rasperry pi. therefore it it deterministic. the Rasperri pi does only IO and higher level stuff.

Re: deployment and testing of code

It would be great if hardcore hackers (who actually can get great things done) would have more love for functional and elegant design as Steve Jobs had (for the tool he ordered from his programmers). Then it would be more fun to use great-tools than having to work with tools that work-somehow and do...

Re: deployment and testing of code

Thank you very much for that hint. The raise SystemExit is helpful. Do you have a solution for the problem for quick access to the SD card from the developer machine when doing development cycles? So I unmount the SD card from the developer machine, then reset the board from the REPL, it starts (wit...

deployment and testing of code

I use a 4GB micro SD card on the pyboard. I do have my code and my log-data on this card. As much as I like micropython, I found out that developing code for it and testing and deploying it on the board is a hassle. I want to have the following workflow: Connect the board to the USB of the computer....
