APA102 #271

Closed Suspect-byte closed 4 years ago

Suspect-byte commented 4 years ago

Hi guys, I am new to this and I found a few things first of all I have a 4 wire cable called Dotstar. I got the APA102. Now I want to use this script with Hypercon to make a bias and audio led strip. I installed the Adafruit dotstar and Adafruit Blinka (because apparently you need those). But I have no clue on how to get these things working. I know which GPIO pins I need but don't know how to get the software working. I got a RPI4 and RPI3b. So I can chose 1 of those. Can somebody help me out a step by step guide. Because the WS281x software (obviously doesn't work for the apa102).

If you have an apa102 library that supports setting pixel colors via r,g,b then you can import the library and replace the line at

RgbColor pixel((uint8_t)packetBuffer[i+1], (uint8_t)packetBuffer[i+2], (uint8_t)packetBuffer[i+3]);//color

With your function.

@joeybab3 Thanks for you response! As is said I am kinda nooby with this so would you mind explaining. I have successfully installed the apa102-pi library "https://github.com/tinue/apa102-pi". In the link, they say I need to install Adafruit_Python_GPIO, but when I go to the site they say that is has been deprecated for Adafruit-Blinka. So my first question do I need to install the Adafruit_Python_GPIO or not? Secondly, how do I change it with my function and where can I find the file to change it? So my APA102 would work with a CLK and DATA wire.

Thanks in advance!

@Suspect-byte I do not own an APA102 strip so I can't really test for it. Check #162 it seems they discussed it a bit there as well.

Closing this as it's already addressed in #162, if you have more questions please ask them there.
