what did you do to get unstuck? :D

Aaz sum misho what did you do to get unstuck? :D

SageBoy•12/2/24, 4:56 PM

Where to start!

SageBoy•12/2/24, 4:56 PM

Ok tell me that what is the advance thing you know it iot!?

SageBoy•12/2/24, 4:57 PM

And what is the most basic thing you know

SageBoy•12/2/24, 4:57 PM

az sum mishoOP•12/2/24, 4:57 PM

i dont know anything :D i am waiting for some components to get delivered and to start

az sum mishoOP•12/2/24, 4:57 PM

i will try to make a website to display the room temperature and a motion sensor

az sum mishoOP•12/2/24, 4:57 PM

with esp-32s, dht22 and hc-sr501

SageBoy•12/2/24, 4:59 PM

Ok!.. search umesh lokhande on youtube and look at it what is embedded video!

SageBoy•12/2/24, 4:59 PM

2nd you need a basic of electronic components!

SageBoy•12/2/24, 5:00 PM

Which you can find at neso academy youtube channel!. Checkout electronic section

SageBoy•12/2/24, 5:01 PM

After that!.. which i am doing is do 8bit microcontroller and processor, than 16 bit. And then 32 or 64 bit

SageBoy•12/2/24, 5:02 PM

( all this look over whelming ik)

SageBoy•12/2/24, 5:03 PM

You also need to learn programing language.
That why just take 2 things in parallel, one is programing and other is electronic

az sum mishoOP•12/2/24, 5:03 PM

i have been programming for a while i just have no idea about the other things :D

SageBoy•12/2/24, 5:04 PM

Oh nice

SageBoy•12/2/24, 5:05 PM

Then you can grab programing concept easily!

SageBoy•12/2/24, 5:05 PM

Btw what is your tech stack?

SSageBoy Btw what is your tech stack?

az sum mishoOP•12/2/24, 5:05 PM

MERN but ive used some python and flask

az sum mishoOP•12/2/24, 5:06 PM

and i want to check out iot

az sum mishoOP•12/2/24, 5:06 PM

sounds fun

Aaz sum misho MERN but ive used some python and flask

SageBoy•12/2/24, 5:06 PM

Damm!... i was also a mern developer before

az sum mishoOP•12/2/24, 5:06 PM

nice :D

Aaz sum misho and i want to check out iot

SageBoy•12/2/24, 5:07 PM

If i really tell you it involve working with new libraries, on different projects. (Btw i am also a beginner).

SageBoy•12/2/24, 5:07 PM

Not like sw or IT work

az sum mishoOP•12/2/24, 5:09 PM

yeah

Hello, @here I have implemented some nice functionality like voltage and current readings using differential amplifiers and also using the GSM module in GPRS mode on an energy meter project I am working on. I will have a session to talk about these things tomorrow Wednesday Dec 4, 5 pm WAT. At the end of the session, we will see why using RTOS will make sense in the project. I would appreciate it if you were present, here is the link: https://app.livestorm.co/p/5507168f-31d9-45b5-9cf8-242db90bc4d8/live?s=79b27e95-039c-4ba8-8d9e-6be2a64e75c7 @ZacckOsiemo @Umesh Lokhande @undefined.elf @Joseph Ogbonna

I’ll definitely check out the energy metering solutions, as they always interest me. I believe the session is at 9:30 PM IST—just confirming the timezone. See you there!

Hi, I was wondering when testing RFID for production, I have noticed that if the RFID tags are in a bundle and stacked tightly together one on top of each other on top of a UHF RFID reader, it will most of the time read the EPC wrong. Is this a hardware limitation or code limitation?

matthewflynn_•12/3/24, 4:01 PM

Is itpossible for me to output different apps to each hdmi port on the pi 5? Basically I have a touchscreen hookedup to hdmi 1 (nearest usbc port) and a projector on the other.

I want to be able to output control program to the touch screen and the projector output a different app?

melta101•12/3/24, 4:06 PM

i think it should be possible with wayland

melta101•12/3/24, 4:08 PM

not sure of the specifics but a startup shell script should suffice

melta101•12/3/24, 4:11 PM

ref: https://wayland.app/protocols/xdg-shell#xdg_toplevel:request:set_fullscreen

You could use these API if you want to make a binary

XDG shell protocol | Wayland Explorer

A better way to read Wayland documentation

melta101•12/3/24, 4:11 PM

This should help you

matthewflynn_•12/3/24, 4:18 PM

cool - thanks for the help - so is each hdmi treated as a seperate output through 1x login and can I just specify each app to a specific hdmi port?

melta101•12/3/24, 4:21 PM

in wayland
it considers display from display output.
So you could specify which app to open with specific display

melta101•12/3/24, 4:21 PM

its an index WAYLAND_DISPLAY

melta101•12/3/24, 4:29 PM

there seems to be a package called wmctrl which does what you want
https://linux.die.net/man/1/wmctrl

melta101•12/3/24, 4:30 PM

but you should know the resolution prior

matthewflynn_•12/3/24, 4:30 PM

thats fine I know the resolution of each screen and it will remain static - its not like I am going to hotswap or anything

matthewflynn_•12/3/24, 4:30 PM

this look good - I'll give it a go!

matthewflynn_•12/3/24, 4:30 PM

Thank you so much for the help

wafa_ath•12/3/24, 5:20 PM

That called tag collision in RFID, it's hardware limitation

I have a tricky one here.
Got Firebox M590 that I want to re propose with linux.
Sadly WG being WG..., it's super locked.
I removed only bootable drive (m2) and noticed that it's still getting grub...

Found, unsoldered and extracted firmware from only flash chip on board, it contains U-boot bootloader.
And that's where Im stuck, I need to modify it to boot from m2...

If there is any magician who knows how to do it, highly appreciated
Can create a thread if needed.

melta101•12/3/24, 6:49 PM

sounds Nice
Is there a uEnv.txt present in uboot

what did you do to get unstuck? :D
