Hi I was lucky enough to qualify for a pyboard d t-shirt pale blue in large. The thing is i don't wear t-shirts and was thinking about selling on ebay giving the procedes to charity. These are rare items i think there was only 50 made. Are you interested in buying it. If i do list it i hope the bidd...

They are just text versions of the constants defined in file errno.h. micropython sticks to these eg ENODEV to remain lean.

If you need a translator to convert these to english you need to write a C program

I've connected a microbit to raspberry pi with direct uart to uart connection

That @mcauser code is bloated. I offered this as a pull request https://github.com/rhubarbdog/microbit-tm1637

The code is slightly bigger, but it's obvious what can be deleted and therefore more useful in the very limited microbit

I believe what @jimmo said is sort of correct.
Mu-editor will plot results from any micropython that has USB REPL. just print your results as a tuple and Mu will plot values on the y axis and time on the x axis.

Have you tried writing your results to a file in csv format and plotting that?

While your doing that is it worth changing this to read Writing to nv ram on the broadcast address (1) will update the nvram of all tile36 meaning that any unwanted brightness settings will be recorded for future use

I've read the docs. The code is sketchy it should read. def set_i2caddr(addr=60, oaddr=1): """ modify I2C address and save it to NVRAM """ ba = bytearray(b'\x02\x0eI2C ') ba[-1] = (oaddr*2) & 0xfe i2c.writeto(addr, ba) save_nvram(addr) The docs are also sketchy After setting the i2c Address you need...

So that nvram should exist on my tile36 allowing me to give the tile an address of something different to 60?

I've just got my pyboard d and tile36. I go to the code examples I copy and paste it to a file add the lines set_i2caddr() random_dots(dt=300) I get the output Traceback (most recent call last): File "<stdin>", line 151, in <module> File "<stdin>", line 39, in set_i2caddr File "<stdin>", line 32, in...

There's a thing called EduBlocks . That mixes blocks with python. It may offer you a solution.
