The above fix was merged into master.

Docs for pyb.usb_mode() have now been updated. Regarding fast data transmission over USB: there has been some (not publicly available) work done to use MSC to communicate between a board and a PC, by essentially memory mapping an MSC block on both the PC and pyboard and then writing/reading the bloc...

To enable high-speed USB you need to pass "high_speed=True" when setting the USB mode, eg This definitely needs to be added to the documentation!

From what you describe it doesn't sound like a heap fragmentation issue. Heap fragmentation would eventually lead to a MemoryError exception being raised, and then MicroPython will drop to the REPL. You can then run micropython.mem_info(1) to get a view of the heap to see how fragmented it is. If yo...

Thanks for testing. I think raw sockets are a good addition (should have been done earlier!).

Would be good to put the uping.py script in a repository somewhere so it can be maintained.

I've been able to add support for SOCK_RAW on esp8266 and stm32 boards, and tested that uPing then works on these ports. See pull request here: https://github.com/micropython/micropython/pull/4946

As mentioned above, you can use frozen scripts to store a bytes object in ROM. An alternative: to load binary data to some external device (here SPI RAM) then you could simply store that binary data directly on the filesystem as a binary file, then copy it to the external SPI RAM device using a simp...

Dear community, This is a brief newsletter to announce that at UTC 17:00 today (15th May 2019) we will make available new stock in the MicroPython online store. All pyboard D-series boards and accessories will be available. And to celebrate that it was just (two weeks ago) MicroPython's 6th Birthday...
