Sylvie sorry for the ping, but nobody on VTOW could figure out the problem, so I figured I would ask you. I’m pretty sure I’ve done everything correctly, and have it set up so that the LEDs should turn on when the program initializes, but nothing happens.
I removed the ping, it’s most likely not code.
see this.
I do want to point out a couple of issues that will be encountered when driving the addressable LED strips from the 3wire ports. Some strips will work directly without needing to do anything about these, however, some strips may need additional logic to work reliably.
The addressable LEDs (WS2812, neopixel) use 5V logic but the 3wire ports are 3.3V logic. The LED want’s to detect logic 1 at 3.6V or above according to datasheet, so really our logic levels are too low. However, some strips I’v…
you may also just want to try this demo using the VEX VSCode extension.
change this line in the demo to use a different port, 22 is the internal 3wire port.
addressable_led addrled(vex::triport(PORT20).A, 60 );

Sorry for the late reply, I forgot that I made this post. As it turns out, every single ADI port on my brain was dead.
