using dfu-util to upgrade pyboard-d firmware

What is the exact command (and options) to use dfu-util to upgrade the Pyboard-D firmware. I am confident about getting the Pyboard-D into (and out of!) dfu mode, but I want to be absolutely certain about the command I need to use to upload the firmware.

How network.WLAN reports a mac address

I'm just starting to play with my pyboard-D and I am a bit confused how it reports mac addresses. for instance, >>> w.config('mac') b'HJ0\x01\xb2\xd0' I understand that the b' means that it is a byte string and that the H means they are unsigned short integers, but I dont understand why there only s...

Re: uasyncio/aswitch : problem cancelling coros on the throw of a switch.

Eventually found the time to get this working. 1. I moved to using NamedTask as this is neater than using Cancellable with groups (at least for my case). 2. Working with classes, and making the 'cancelling function' a bound method gives a neat function/method to pass to the aswitch objects. (see the...

Re: adhesive/insulation for electronics in soil

Caveat: the following is based on opinion rather than first hand experience: I think you might have a conflict between your requirement to water proof your electronics and your requirement not to leach any undesirable chemicals into your soil. I believe that there are two types of silicone sealant, ...

uasyncio/aswitch : problem cancelling coros on the throw of a switch.

I am having problems cancelling a coro using await asyn.Cancellable.cancel_all()) from a aswitch close_func() call I have successfully used aswitch to (a) send an event to a coro to get it to continue running (b) set a parameter to terminate a while loop, i.e. loop=asyncio.get_event_loop() self.cons...

Re: Beacon frame timestamp alt to ntp

Where is the problem with using NTP? I will admit that I don’t understand how to connect to an NTP server and what the effect of network delays etc might be on accuracy, but a very cursory look at examples of NTP clients written in Python makes it look simple, Am I missing something. ...
