Re: bits to bytes
Well, ASR33. OK, you win. I did use teletypes at university for a very short time (maybe one term). I remember a really interesting one that used spark discharge to print on the paper (how many people know that, at some point in time, terminals actually used paper and did not have a display?). It us...

Re: bits to bytes
So no easy way to get b'40 80' ? Seems to me python is being as slippery with octal/hex here as it sometimes is with types? When debugging I always do something like this: [hex(n) for n in bytes_or_bytearray_variable] <Rant mode on> I can't stand some aspects of the Python bytes and bytearray imple...

Re: Any zlib.DecompIO examples?
Well, it was easier than I thought. Here is it for the benefit of others who might need to figure this out: import zlib compressed_text = b'\xf3LS\xa8\xcc/U\xc8*-.Q(O\xcc+Q(\xc9W(JMLQ\xc8/R(/\xca,IUHTH\xcb\xccI\x05\x00' uncompressed_text = b'If you just want to read or write a file' # Create file wi...

Any zlib.DecompIO examples?
Trying to understand various ways to use this class. Anyone know of any nice examples out there? Google has failed me. One of the things I am trying to figure out is how to decompress a large compressed chunk of data without using very large buffers. I can seek to the compressed data in the file...a...

Re: Access to UART ring buffers
Just putting a byte into the ringbuffer does not mean it will be sent. Unless sending is already active, the send process has to be initiated. So what you need is a lightweight version of uart_write(). That has as well to cater for the case that the ringbuffer is full. True. That's pretty much what...

Re: Access to UART ring buffers
But... this sounds like it would be a lot easier to fix in machine_uart.c (i.e. add a helper method that does what you need). I think this is likely where I am headed. It will be a couple of months before I can take this path though. My preference would be to try and contribute something potentiall...

Re: How does _SOME_CONSTANT = const(2) work in a class?
I get it. It's just that "unclean" feeling of not having everything inside the class definition. Not an issue at all.

Re: Is this a bug or a feature?
I thought I reported it on github. The last few weeks have been a blur. I'll put it back on my list.
Thanks.
Thanks.
