Hello again,
BiblioPixel newbie here! I am working with a simple LED strip code example given to me that uses the update() method. My understanding from reading the wiki was that animations need to be written separately from layouts. I also see in the error message from running the program that the update() method is deprecated. I checked in the Strip class for a successor and didn’t see one. I am not sure if I just need to modify this program or redo it in a totally different format.
Is this form of program still supported/valid? I like how the script is simple and lets students program the LEDs procedurally, so I would like to keep this kind of format if that is still supported. If it is out of date, what would be the steps/best practices for updating it?
Here is the important part of the program: (demo-test.py)
### Initial setup
numStrips = 1
numLeds= 10 * numStrips
driver=DriverLPD8806(numLeds, ChannelOrder.BRG, False)
led=LEDStrip(driver)
### Each LED turns on serially
####Once done they all flash ON & OFF till user ends the program with CTRL + C
led.fillRGB(0,0,0) # turns everything off
led.update()
Pick Random Color
color = (random.randint(1,180), random.randint(1,180), random.randint(1,180))
for i in range (numLeds):
print ('LED '+str(i+1))
led.set(i, color)
led.update()
time.sleep(0.25)
``
Error message when running: ($ python demo-test.py)
