All,
I got my Ambilight system mostly up and running this weekend. I'm using a RPi3 and a (clone) Arduino Uno to run a string of WS2812 LEDs, using the built-in V4L2 grabber pulling input from an STK1160 USB capture device.
The good news:
- All LEDs blink just fine as part of the Arduino startup routine (and I've now disabled that so it goes straight to it's "ready" mode.
- All LEDs respond to effects picked via the HyperCon Android app. It switches back to actively responding to what's on the screen when I turn the effect off.
The weird part:
- Almost all LEDs update and react to what's on the screen without issue, with the exception of the last LED in the string.
As I said, all LEDs blinked in the Arduino's startup sequence before I disabled it, and all LEDs work fine in effects and the color wheel.
I am using the Arduino Sketch found @ https://github.com/hyperion-pr…ino/adalight/adalight.ino. When I was setting it up initially I ran into a problem with the last LED not lighting up until I commented out the following part of the Sketch:
if (ANALOG_MODE == ANALOG_MODE_LAST_LED) {
ledCount--;
}That brought the last LED online in the start-up sequence (though I couldn't find where I could have misconfigured the Analog options that would have made it go through that if statement), but not for the actual Ambilight operation.
I then took the Sketch and edited out ALL the analog configuration and function parts. The result can be found here: [MEDIA=pastebin]hsEZFM4F[/MEDIA]
My config file can be found here: [MEDIA=pastebin]X21BcF2y[/MEDIA]
I have a total of 222 LEDs in my string, which is set in the config file, with it showing config for LEDs 0 through 221.
And for completeness, here is the results grabbed from my log after starting/re-starting Hyperion.
