FINALLY! Turns out it was an issue with the HDMI + HDCP.
I'm pretty sure you need adalight as the led type, not adalightapa102
I'd also try changing the arduino sketch and Hyperion config to use 115200
Some good news! The Arduino and Pi now talk to each other. Here's what I had to do:
After getting everything to communicate I had another problem. Depending where you look, the APA102-C LED color order is documented differently. With a little debugging I found the correct color order and updated my sketch
With those problems solved I ran into an issue where the LEDs would flicker with fast moving effects:
I think I've reduced this by grounding the LED strip to the ground pin on the power side of the Arduino. I had previously grounded the LED strip on the other side.
My HDMI to RCA adapter doesn't appear to be pulling a signal from my HDMI splitter. I think I have a defective adapter...but it could be an issue with the HDMI splitter and HDCP. I have a replacement HDMI to RCA adapter on the way.
But, here's where I'm at today:
Any suggestions?
No resolution on my end.
Making sure the Rpi can communicate with the a arduino without issue on /dev/ttyACM0
Oh, I've confirmed that the RPi can talk to the Arduino. With the latest changes I can issue commands from the RPi to the Arduino and change the LED color, but only a handful at a time (see above photo).
As a test, would it be possible to install the arduino ide on the Rpi and see if it can upload the sketch without issue?
I'm not sure what this would accomplish since I can confirm I am able to upload sketches.
I have another idea that may resolve the issue. Try the Official sketch. ( https://github.com/hyperion-pr…ino/adalight/adalight.ino)
It may work better for you. I know it did for me.
I am already using the official sketch.
Are you uploading the sketch via the arduino ide on the Rpi?
No, I'm plugging my Arduino into my laptop and uploading from the IDE on there..
Out of curiosity what does " sudo ls -l /dev/ttyACM0 " return on the Rpi?
BoxOfLights:~ # ls -l /dev/ttyACM0
crw-rw---- 1 root dialout 166, 0 Mar 31 18:41 /dev/ttyACM0How many LED's are you using? I ask because the two sketch's have different values. One for 240 and the other for 168.
I have 168. The 240 value was a default when I was trying to determine the color order.
Okay, another update. I believe the RGB byte order provided online was incorrect. I loaded another sketch to test and found BRG gave me the correct colors on boot. After setting the correct color order on the Arduino to BRG and keeping the Hyperion config at RGB it looks like I can control a single LED. This is odd.
On first boot with Pi + Arduino this is the resting state, note the LEDs that are off:
When I connect with the Hyperion Android app and use the color wheel and choose yellow:
Gist => Test sketch
Okay, I've added the ground wire on the Arduino. I don't think I need to ground anything on the RPi.
When I send commands to change color from the command I can see the LEDs doing something, but I'm still not seeing any solid color or working effects.
I double checked the manufacuter site and read:
ZitatThe manufacturer of the APA102C smart LED used in this strip used to be GRB order, and has changed in 2015 to have BRG color order. This means if you are using our DotStar library, you’ll need to change the initialization to tell it which you are using. Check the tutorial for details on how to do this! The LED colors are otherwise identical, you just have to pipe the data to it in a slightly different order.
I updated my Arduino sketch to use the BRG color order while keeping the Hyperion config to use RGB. Still no luck and everything is white.
The Arduino picture is missing a ground pin.
Hope it helps.
Do I ground it to the PWM side, or the Power side? I've tried both, but there is no difference. Thanks!
Hi all, I've been making progress with my setup at home but am encountering some problems. I have the my LED strip connected together and talking to the Arduino (verified by loading a different sketch). I have verified Hyperion is running, and my phone can successfully connect to the server. I have not added an inline capicator
When I power only the Arduino, I see a quick, successful LED test. Once the Pi and Arduino boot up I see a quick LED flash, but do not see the rainbow swirl effect.
I am unable to control the LEDs through Hyperion. When I SSH into the Pi and manually set a color I see confirmation from Hyperion, but nothing on the LED side. I'm not sure if it's a configuration issue with the Arduino, or a communication issue between the Pi and the Arduino. Thanks for any help!
