Need help wiring correctly using HyperSerialPico as LED driver #927

Hey y'all!

I have been running HyperHDR for some time now using the deprecated way of wiring the LED on the Raspberry Pi GPIO without any LED driver.
But I would like to change that to use the proper way to do it now, I opted for using a RP2040 ItsyBitsy for that as mentioned on HyperSerialPico
For now, I've not been able to turn my LED off with this setup, so I wonder if I wired things correctly.
Here is a simplified setup (without the splitter and the capture card) of how I did it

I feel like I did something wrong with the ground, and I'm afraid it could be dangerous to be honest 😅
Also, something that can be worth mentioning, I'm trying to run HyperHDR in docker, as I would like my Pi to act as a homelab rather than being dedicated to HyperHDR, which might cause issues with communicating with USB and stuff like that 🤷‍♂️

Thanks all for your help!

Hi
I have always recommended using dedicated power supplies for RPi due to voltage instability/fluctuations in LED power supplies. Unfortunately, you are using Rpi5, which requires identification of the power supply by PD https://github.com/raspberrypi/documentation/blob/develop/documentation/asciidoc/computers/raspberry-pi/power-supplies.adoc
otherwise the current for all USB ports will be limited to a ridiculous 600mA, which is a huge change compared to older designs (e.g. RP4 will always try to drive all USBs up to 1.2A). In the case of Adafruit ItsyBitsy itself it may still work, but if you also connect a grabber I don't know what will happen.

And for the meritum you are using wrong GPIO:

GPIO14 (5! label)

@awawa-dev Thanks for the quick answer!
Oh I wasn't aware of such a limitation with USB ports, I could still use the official power supply for the RPi if it doesn't work as expected.
But I would have to take the ground wire from the led strip to put it the RPi ground GPIO right? or both?
Otherwise I might have an old RPi 2B somewhere but it might not be powerful enough

In your current setup you already have a common ground. If you use a separate official power supply for the RPI5, you need to connect the ground from the Adafruit ItsyBitsy to the ground on the LED strip to have a common ground with the LED power supply.

Otherwise I might have an old RPi 2B somewhere but it might not be powerful enough

I would stick with RPI5 because of USB3.0 if you have also a USB3.0 grabber.

BTW there is new usb_max_current_enable option just for RPI5 (not to confuse with the old & unsupported max_usb_current ). Do not know if there is any danger related to this option.

I'll try without changing any config, and I'll check that option if I'm running into some issues, thanks a lot for your insight! 🙏

@awawa-dev I almost have everything working, but the LED strip, as I get these logs

Can this wire be from the RP2040, to the ground of the power supply instead?

awawa-dev Aug 25, 2024

Usually it should work too if the wires are not too long

qeude Aug 25, 2024

They would be very short

I was finally able to try it for a few hours, and it has been working flawlessly, thanks for your precious support!
I'll have a look later to make it work on docker though

You can try Docker again because previously the 'rp2040 handshake' was disabled.
