BluePoV is a persistence of vision display, just some leds rotating at ~2400rpm creating the illusion of a floating image, communicated over bluetooth with a pc or an android device.

This driver allows any program written in Python to send it a pixel matrix asynchronously, and configure some variables.

The display, developed over 8 weeks, is the final project of Pio IX secondary school.

• Python 2 || 3, works under both.
• numpy.
• cython, if compiling the encoder.
• For now, only pygame's surfaces are supported as the input data.

And depending on the communication method:

• Bluetooth works natively under python 3.2+, for py2 pybuez is needed.
• The serial port needs pyserial to work.

The bit-encoding part is written in C, so it must be compiled. Under encoderSrc/ there is a setup.sh and a setup.bat, use the appropriate. They will try to compile for both the py2 and py3 versions.

There is an example.py with a simple setup and usage. Also, there is a drawing program coded by my partner using it.

# Everything is inside this module
import BluePoV
    
# Create a bluetooth or serial socket and connect to it
# sckt = bluePoV.BluetoothSocket()
# sckt.connect(MACaddr='12:34:56:78:9a:bc', asServer=False, port=3, timeout=0.1)
sckt = bluePoV.SerialSocket()
sckt.connect(port='/dev/ttyUSB0', bauds=9600, bytesize=8, parity='N', stopbits=1, timeout=0.01)
# Once connected, both sockets work equally

# Create the interface
# It will spawn a new thread, so we can send the data asynchronously
driver = bluePoV.Driver(socket=sckt, res=(480,64), depth=1)


# Now we can use it

# Check if it is connected
if driver.ping():
  echo('Yeah!')

# Clean the display
driver.clean()


# Refresh all the display
driver.pgBlit(pygameSurface)

# Or only part of it
driver.pgBlitSection(pygameSurface,pos=32,lenght=16)


# Change some parameters
driver.setResolution((240,128))
driver.setSpeed(0xf48)
driver.setDim(False)

# And get others
echo(driver.getFPS())
echo(driver.getDepth())
