Hey yall, first time posting! I’ve been trying implement an addressable LED strip on our bot, and I’ve been reading up on some documentation, I’ve tried to use the method listed on the VEX Pros API documentation but I cant seem to get it work, I read on past posts that the number of LEDs on the str…

i need to talk to my programmers but could you use these with vexcode? We used leds in FRC and loved them but I dont know that with us its possible in vrc. WOuld we have to transfer to vs code or pros to do this?

You could with C++, the code linked here could be easily ported. [image] GitHub - jpearman/V5_addr_led_demo Contribute to jpearman/V5_addr_led_demo development by creating an account on GitHub. or for Python. [image] V5 Addressable LED…

I understand that and did in fact look into that, but thus far all my bot’s code have been written in PROs, and it would be a difficult pivot, is there no way to resolve this issue in PROs?

I’ll go try the solutions listen here, thank you!

It should work ok from PROS, I did a quick test using latest kernel. void initialize() { pros::lcd::initialize(); pros::lcd::set_text(1, "Hello PROS User!"); static pros::adi::Led led (1, 60); pros::delay(1000); led.set_all(0x800000); //led.update(); pros::delay…

Sorry, I’m not the brightest of the bunch :pensive: Could you please explain what a level converter is?

would these be counted as microcontrollers and technically not allowed under vex rules?

What are you using for the 5V source? It doesn’t seem possible to reach 5V exactly with AA batteries.

V5 Addressable LEDs VEX V5 General Discussion

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…
