DmxPy test programme issue

[philarnaud]

Hello Sir DavePaul,
I have installed your DmxPy on Raspbian (simulation of a RaspBerry PI on a VirtualBox on my PC.
When I connect usb DMX key (Emtec), I can see "usb 1-1.4: FTDI USB Serial Device converter now attached to ttyUSB0. So I use /dev/ttyUSB0.

Then I run python dmxpytest.py with follwing contents:
python dmxpytest.py (here after)

• It start for half a second and come back to command line
• Red led on adaptater is blinking twice then come back to black
• Par led is flashing half a second in Red Green.
• it seems that delay is not taken into account to wait between the 2 effects!

Do you have any idea of what it could be?
Best regards
Philippe

from DmxPy import DmxPy
import time
dmx = DmxPy('/dev/ttyUSB0')
dmx.setChannel(4, 255) <- I have a small PAR LED RGBW Channel 4 is light intensity
dmx.setChannel(5, 255) < is RED intensity
dmx.render()
time.sleep(2)
dmx.setChannel(6, 255) < is GREEN intensity
dmx.render()
time.sleep(2)
dmx.blackout()
dmx.render()
