muccc / flipdots Goto Github PK

the method blitTextAtPosition in flipdots/scripts/FlipdotAPI/FlipdotMatrix.py is recursive. unfortunately python crashes on huge recursion depths....

the current one is slow and produces strange pulses on the /CS line.

Have a look a https://github.com/mstaflex/SPI-Py or quick to wire

Something like dynDNS for the 3 IPv6es of the flipdotwall could finally end the mess with manually editing the prefixes in all the scripts everytime the wall moves...

make API python3-compatible

title says it all...

We need something like pixelflut to run on the "wand".

As shown on 31C3: https://github.com/noniq/flipdotwars – short video here: http://www.youtube.com/watch?v=9COjimqT3hw

(Not an issue, of course, just a notice 😃 )

The python file flipdots/rpi-demo/udp_receiver_and_translator.py runs on the zeile and the wand for the following reasons:

• enable and disable 24V power as required
• fix the strange orientation of the flipdots in the zeile.

Both should be features of the the udp-receiver.c

There are a number of python2 scripts in the scripts directory which should be converted to python3.

Typical issues to be encountered will be the use of strings as arguments to socket.sendto. This behaviour has changed with python3. socket.sendto now accepts a byte type as argument.
Ideally these affected scripts would be modified to use the FlipdotAPI which takes care of sending data to the flipdot matrix.

as seen at the 33c3, a webapp like https://github.com/trezor/homescreen-editor is a great improvement to send images to the flipdotwall.
just slight changes in mentioned repo need to be done, but we need a receiver for image files via http-post or something similar...

wanted methods:
getLineHeight()
getWidthForLetter( )
getLetterImage( )
