Haven't had much time to work with this lately..... Although I'd tried different USB ports (and the cheapo hub wasn't very!) - I'd tried multiple ports on the PC (a modern machine - MSI motherboard, i7) without joy. That seems to work - connected to an old laptop (a ~7 yr old Core-2) and all seems w...

A possible fix - flashed board with latest version of dfu file from: http://micropython.org/download/ using the Dfuse demonstration from: http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1533/PF257916?s_searchtype After a worrying few minutes where the board wouldn't come out of dfu mode ...

Also happens with the board attached and no activity at all (empty main.py) and no terminal connection. Trying to connect after ~5mins doesn't work without a board reset..

Tried with different cable, port and computer. It 'appears' that the input loop of the interpreter crashes - putty giving error writing to serial port - restarting putty gives a fixed cursor, and Ctrl C etc have no effect. When running a program (main.py - Life in a loop) - the board runs happily fo...

Certain MicroSD cards cause the micropython board to reset after 30 seconds.

No - happens with a 'bare' board. It also happens with LCD skin attached and/or a servo.. I'll try another cable / usb port (on the pc rather than the hub) this evening.

I get a problem with the pyboard disappearing after a few minutes of not being used (ie no input - occasionally doing so while typing too). Using Putty (on Windows7) and with the board connected to a USB3 (powered) hub, putty gives "cannot write to serial port". I can open the card from Explorer - b...

A tutorial has just appeared for this:

Details of how to read the buttons too!

More good stuff!

Code for Life: Very little changed from the github source - just the lcd initialisation and the random number selection #import essential libraries import pyb # do 1 iteration of Conway's Game of Life def conway_step(): for x in range(128): # loop over x coordinates for y in range(32): # loop over y...

After a while of playing: lcd = pyb.LCD("X") or lcd = pyb.LCD("Y") Is the required code - depending which end you've plugged the lcd skin into. Then using the terminal: lcd.light(1) - and the backlight was on - and in business. With a few modifications I got Conway's Life to work >>> help (pyb.LCD) ...

Just received my micropython board and LCD pyskin - board up and running nicely (& an interesting bag of bits to play with too) So turned my attention to the LCD (first sample code I found was for Mandelbrot) - soldered some header pins and plugged in. How to get the LCD to work - lcd = pyb.LCD("wha...
