But for that purpose, RTS/CTS line information must also be accessible. Not sure if this is possible in uPy... In a recent patch (yesterday) I added experimental RTS/CTS support. There are 2 uarts on the pyboard that have these lines available. The way it's implemented is that you say you want flow...

Are you typing pyb.freq(30000000) at the REPL prompt when connected over the USB serial? Can you try pyb.freq(168000000) and also pyb.freq() to see what the output of that says?

The pyb.freq() command supports frequencies (in MHz) between 24MHz and 168MHz, and it rounds them to a compatible value. Sometimes when you change the frequency while connected over USB you will lose the USB connection, but this doesn't happen very often. And I think pyb.freq(24000000) doesn't allow...

I have made a pull request for custom HID functionality, including keyboard and mouse:

https://github.com/micropython/micropython/pull/955

Thanks for pointing this out, I agree it's pretty unconventional behaviour. It is now fixed in the latest version: bits specifies the actual number of data bits, and if you enable parity then it adds an extra bit. So your original initialisation will now work. BTW, you may be interested in this code...

There have been a few requests now for extended HID functionality, so I'll start to look into it. The idea would be that on boot up you specify "custom HID" and pass the HID descriptor, eg: descr = b"\x01\x02\x03..." pyb.usb_mode('HID', descr) Of course, the descr set of bytes will need to define a ...

Using pyb.wfi() allows you to reduce power consumption by about 1/2 if you are waiting in a loop. Consider: sw = pyb.Switch() while True: if sw(): print("switch pressed") versus: sw = pyb.Switch() while True: if sw(): print("switch pressed") pyb.wfi() The second code will run the same, but use about...

Damien mentioned coming out with a Lite version (which I'll speculate is based on the STM32F401 - which is around $8 Qty1 and in the $3-$4 Qty a few thousand). That's right, I'm working on a Lite version of the pyboard which is based on an STM32F4 chip. I have a prototype which is working. It is ex...

Awesome.

Can this script live somewhere in the micropython repo (eg tools/ subdir), so that "make deploy" just works?

The cc3k.recv() method was trying to do multiple recv calls to get the requested buffer size. This was wrong behaviour that is now fixed. I don't know if this is enough to fully fix your problem, but give this version a try: https://micropython.org/static/download/pybv10-network-2014-10-22-v1.3.4-1-...
