That was the mechanism I had in mind in my post of 23rd June, albeit applied to a class not subclassed from int. Subclassing from built-in types is only partially supported in MicroPython https://github.com/micropython/micropython/wiki/Differences so it's questionable whether Guido's approach would ...

I'm no expert on the WiPy so I can't answer your main point, but the circular buffer in _addData_ looks wrong to me. Try this:

Looking at my code again it was originally ported from Javascript. The original source website has disappeared into /dev/null but I've put a copy here http://hinch.me.uk/riset.html . You can run the code to check the results of your port. Also if you examine the Javascript you'll see code for civil,...

@patvdleer I've posted it here http://hinch.me.uk/lunarmath.c It doesn't support twilight phases. There is a lot of code concerned with lunar calculations which you can obviously eliminate, and you'll need to adjust the latitude and longitude for your location. If you decide to port it to Python, my...

Perhaps what's needed is an enhancement to Python syntax enabling the slice notation to be applied to integers stm.mem16[stm.GPIOA + stm.GPIO_ODR][14] = 1 stm.mem16[stm.GPIOA + stm.GPIO_ODR][14:18] = 0b1011 >>> a = 0 >>> a[10:12] = 0b11 >>> hex(a) >>> '0xc00' I doubt you'd get it past Guido ;) Or Da...

wrt fonts one technique I found quite useful is to store bitmap images of antialiased fonts on the sd card... There is a potential performance issue here: performing a file random access for every character can be slow. I've used this approach for driving ePaper displays where the device is inheren...

I have some C code for calculating sun rise and set times which I can provide if you wish. It calculates to an accuracy on the order of +- a minute, which is probably better than you need. One option is to port it to Python to run on the target (which should be easy). Alternatively adapt it to creat...

Have you altered boot.py or main.py? It sounds as if it might be executing a program.

You could define a class in Python such that code like a = InstanceOfMyClass() a[12] = True would set bit 12 of some underlying hardware register. I don't think it would be remotely as efficient as the code you cited: stm.mem16[stm.GPIOA + stm.GPIO_ODR] ^= BIT14 The const() declaration means that th...

My guess (and it is just a guess: I don't use Windows) is that it's a terminal artefact. It looks to me as if Hyperterm is set to 80 columns and isn't handling line wrap. It displays 80 characters correctly, but then puts subsequent characters in the rightmost column, repeatedly overwriting column 8...
