so you can use right one for only power

Mmatthewflynn_Hi Guys - any one have any tips for external monitors on the raspberry pi 5? I h...

melta101•12/2/24, 10:01 AM

do you need a 15 inch monitor?
just curious of the use case

segfaultdev.elfOP•12/2/24, 10:01 AM

and left one for data + power

Ssegfaultdev.elf so you can use right one for only power

matthewflynn_•12/2/24, 10:04 AM

thanks for that - I'll give this a go.

Mmelta101 do you need a 15 inch monitor? just curious of the use case

matthewflynn_•12/2/24, 10:04 AM

yes and no - its a prototype machine where I need to be able to provide the user with touch screen interface to adjust actuator settings.

matthewflynn_•12/2/24, 10:05 AM

so it does need a touch screen interface for interactivity - not necessarily 15" - it was just in the black friday sale lol

melta101•12/2/24, 10:05 AM

why not a standard 7 inch screen used normally for rpi

melta101•12/2/24, 10:05 AM

you could use hdmi or mipi CSI is even better for that

matthewflynn_•12/2/24, 10:06 AM

the pi is actually mounted underneath the proto unit and I have a 2m cable running to the device.

damn

I suppose I could - also the external monitor had a nice finish to it and could easily be mounted

it's okay for prototyping but powering a 15 inch monitor won't be much efficient if you think about the facilities it will give

matthewflynn_•12/2/24, 10:11 AM

No i agree - I missed that I could power it through the second usb port. I'll give this a go but I have my finger crossed lol.

segfaultdev.elfOP•12/2/24, 10:12 AM

okok

matthewflynn_•12/2/24, 10:14 AM

but as an overall solution as long as I provide power through the 2nd port - it shouldn't draw from the pi? Do you think I need to rethink this?

segfaultdev.elfOP•12/2/24, 10:19 AM

I don’t know actually what will happen then but I think it should have internal protection so that both port can be isolated from each other

matthewflynn_•12/2/24, 12:40 PM

Thanks for all the help guys - I seem to be getting somewhere now (hopefully). I have a usbc cable on power block into display port 2 (for now I just have the usb connection disconnected for testing). when I plug in the HDMI to the monitor the pisture appears for between 5-10 second and then the signal seems to drop? (it remains powered as it flashed red/green/blue cycles). which if I then unplug and replug the hdmi back in the screen appears again.

Now the monitor is mini HDMI so I currently have it connected through a mini HMDI to full HDMI adapter, then micro HDMI to full HDMI?

could this be the issue for the signal drop?

Hey team I am facing an issue, I have a raspberry pi 0 2W and I am trying to interface it with a imx219-160 camera module. However it does not seem my rpi is detecting the camera

Your Raspberry Pi isn’t detecting the IMX219-160 camera module.
Verify Detection Check with

vcgencmd get_camera

vcgencmd get_camera

. It should show

detected=1

detected=1

Umesh Lokhande•12/2/24, 2:00 PM

Try following steps:
1. Install bullseye os on your raspberry pi
2. After booting raspberry pi enter below commands

sudo raspi-config-> interface-> enable libcamera-> save->reboot

sudo raspi-config-> interface-> enable libcamera-> save->reboot

sudo nano /boot/config.txt

sudo nano /boot/config.txt

(enter this command, scroll down till last [all]) under [all] enter the command "dtoverlay=imx708"
Now, save and reboot raspberry pi
Enter libcamera command-

sudo libcamera -hello t 0

sudo libcamera -hello t 0

And check if the camera is detecting or not

In new Raspberry Pi OS you may not get camera. As it is enabled by default.

ZacckOsiemo•12/2/24, 2:04 PM

yes that's what the docs say

ZZacckOsiemo I'm aware thanks

Renuel Roberts•12/2/24, 2:05 PM

check ur configurations in this file

sudo nano /boot/config.txt

sudo nano /boot/config.txt

Renuel Roberts•12/2/24, 2:05 PM

if this parts are commented

dtoverlay=imx219

dtoverlay=imx219
start_x=1

RRenuel Roberts check ur configurations in this file `sudo nano /boot/config.txt`

ZacckOsiemo•12/2/24, 2:05 PM

that file moved to

/boot/firmware/config.txt

/boot/firmware/config.txt

and I have checked it

Renuel Roberts•12/2/24, 2:06 PM

then i suggest u update and reboot the system

ZZacckOsiemo yes that's what the docs say

Umesh Lokhande•12/2/24, 2:06 PM

So I suggested to go got Bullseye release of Raspberry Pi OS and then try Camera. last time i tried with new RPi OS , there were lot of issues. This may save your time.

ZacckOsiemo•12/2/24, 2:08 PM

Do these optioons matter if I am on headless rpi?

it depends on on which RPi OS you're using Camera with

It's been 6+ months for me and not sure if the camera-related issues been fixed in new updates of rpi os but if you find it difficult to resolve then move to A stable legacy version of Raspberry Pi OS Bullseye.

ZacckOsiemo•12/2/24, 2:21 PM

I will consider that shortly

Renuel Roberts•12/2/24, 2:27 PM

can u verify the camera module is working on its own
