BS 6146-1 parallel interface specification?

Hi I have an old weather station from mid 1980 years equipped with a so called BSI (BS 6146-1) parallel interface (8 data + 5 control lines, TTL levels). Unfortunately I can't find details how interface works. Does anybody have information using control lines, extract of the standard, etc.? As far a...

uPython for chipKIT boards (PIC32)

Talking about Microchip PIC32 chipKIT boards are good targets to port. There are different boards both with 128k and 512k flash. Great advantage is that board layouts, connectors are mostly compatible to Arduino shields and there are cipKIt boards too. For details see: http://chipkit.net/products/ T...

Re: deployment and testing of code

Under linux, I don't bother unmounting. I just edit the file, copy it across, wait a few seconds for the file writes to finish, press Control-D on the REPL and retest. Occasionally I'm too fast and the file doesn't get written properly. It is a bad parctice, you can't be sure data is really written...

Re: Not easily impressed...

Talking about Arduino, pyboard has a much higher specs hardware than Arduino boards. But the key differentiator is micropython as others already explained.

Re: another python on micorcontrollers project

One thing I usually check is Python exception support. And none of the existing implementations has something which can be classified as real Python exceptions. I'll tell you why - because it's hard to implement them (you need design VM with them in mind, and then spend bunch of nights to debug the...
