So, what do you think about the live team coding idea? Tried something like that before?

MNever tried it - but would be up for it.
UThat is why we use AWS EC2 Instance to deploy client's IoT dashboards to handle higher traffic generated by iot devices (to save server from crash). They are very scalable. I'm not suggesting the use of EC2 for this case but just saying that the similarity between device-to-server and client-to-server communication!
BHey guys 4 years experienced Embedded Developer here 
Experienced in Hardware + firmware design complete projects.
Any project idea suggestions to get into Embedded AI space ? (Training myself to fetch big bucks 1-2 years down the lane). Please suggest

THey Bruce, are you familiar with TinyML?
ZOh wow I have something to teach you then 
EHi tinyML would be a good place to start . Also, if you are looking at speech to text or something related to audio in AI, you can try Picovoice. For the two options, they have specific devices supported. I did a project using Portenta H7 on controlling things via voice commands.
E
Project: Control LED using voice commands(FULLY OFFLINE AND ON EDGE)
Board: Portenta H7
Steps:-
1: A…
BYes have been trying to research about moving into this space online. Overwhelming information available regarding entering the ML / AI space. 
BThank you, will check this out right away.
T@Renuel Roberts any tips for Bruce to get started?
RHello @bruce_wayne are u familiar with python
BYes absolutely. All my career I’ve been scripting using Python and sending commands over Serial or Ethernet to automate testing.
RAhv u worked with any AI related libraries like decision trees, Tensorflow lite and pandas/ numpy or matplotlib for mL
RIf you haven't, start by Data manipulation using pandas and NumPy, understanding algorithms, and working with libraries like Scikit-learn, TensorFlow, and PyTorch.
U can start by creating basic AI chat not till u understand the logic flow to move into complex projects

K@techielew I was just reading the scroll back, this is quite interesting, it also sounds almost identical to a hardware in the loop ci setup with the key differences being we push from users instead of source control (I guess it would be encumbering for users to push git to flash the hardware?) And that users want to poke/shoogle/look at the hardware instead of automated tests.
I'd be interested to discuss further / help with this.
My gut feeling re the aws thing is I'm on the side of the $5 linode - I'm generally of the opinion that if the part talking to hardware needs to scale for users the architecture was built wrong - we usually run these things on something in the raspberry pi territory
P.s. - if you do use a PI, you get the gpios/busses so it's easy to hang off a couple of i2c/spi devices to stimulate various parts of the system, the linode would basically serve some rpc interface which should be very light and the "fancy web stuff" can be done client side - the linode is more there so that you arent exposing a pi in your house to the nasty world

Zyou need to teach me so many things please 
Zwow I didnt know v2x was a thing already, this is really amazing.
KIn essence - look at hardware in the loop testing
Consider that a lot of the setup is identical
You could actually drive a system like this from git, people drop a link into some things, when it's their turn the system picks up the code flashes it and runs it.
The difficult part here is if you want people to be able to interact with the target in realtime - now just throwing jobs at it doesnt work, it becomes more like booking an appointment.
We were talking about building something like this on another server for an embedded advent of code, we hashed out some ideas but didnt have the time to commit and make it happen

Zlet me read up a bit, keen for this December maybe on this server let me see what resources I can gather, I'll come back with questions
Rwhen working with Zephyr OS for embedded systems, what do you find most beneficial?
@Dtynin @Boss lady @melta101
I noticed you guys have work on some projects using zephyr can you please share some of your insights

KNot tagged but the HAL and the use of device trees gives more hardware abstraction than other options. The closest thing in terms of completeness is the arduino hal
The general quality of the drivers is also good enough that you don't have to hack it up all the time
The general quality of the drivers is also good enough that you don't have to hack it up all the time
RThat's a great point, Zephyr’s HAL and device tree really do provide that extra level of hardware abstraction, which can simplify development significantly. How would you compare working with Zephyr’s device tree to other approaches you've used in the past? Do you find it as intuitive, or are there challenges you’ve had to overcome to fully leverage its potential?
TYeah looking at it like scheduled HIL testing is a good point. There's a way to do this that could be much less expensive (ie, linode) and not reinventing the wheel if we're willing to do round robin 'appointment' scheduling. It's not what was originally envisioned, but perhaps a necessary next step.
We'd certainly welcome the assist, @ke7c2mi. Thanks for the offer. I have a lot going on this upcoming week but hopefully we'll be able to regroup next weekend.
Also, I'm open to any ideas from anyone that would provide an alternative to the "scheduling/appointment" phenomenon, which would be annoying.

TMaybe it's an extension of the AMA we just did with Ming. You have to submit your question and code ahead of time and then we'll select ones that are of the broadest interest and let that user 'drive' under guidance of the instructor/expert.
KI don't think it's particularly intuitive and I think it's quite a steep learning curve coming from bare metal / reading datasheets and poking memory. It has felt cumbersome for me compared to things like freertos/rtic/baremetal.
Device trees themselves are neat, and I think pretty intuitive. It's just some descriptive templatey IDL. On the other hand they map to your entire system in an abstract way so actually doing things with them can be complicated - the device tree itself isn't the problem there though!

CHey Guys Cherry here, just joined the group. Excited to be here. Little intro about myself. I am a recent grad with over an year experience as an Embedded Software Developer.
BThanks for the suggestion. @Edison_ngunjiri also suggested a tinyML project that involves hardware and code that runs on a microcontroller. Am I correct to assume that it would be the first thing I need to understand as the step towards AI/ML in Embedded Systems?
Zfelt the same to me it was odd
ZWelcome Cherry, let us know what you are working and any way we can assist.
MIt's pretty neat
Was able to ship few modules with Zephyr on it.
Development is pretty direct especially since I like Linux kernel and the whole dts style of development.
One oof moment was the difference in opensource licence between the Linux kernel and Zephyr
Had to take down my PR due to the incompatibility

Where do you work/what do you work on currently?
Where do you work/what do you work on currently?EIf you are interested in ML/AI in embedded systems, I would suggest you go right into it.
Just repeat the already existing projects on tinyML/picovoice.
With these two platforms, it's more of a process than actual coding.
After several projects ,you may want to look at pandas,numpy and scikit-learn for more understanding.
This has always been my approach.
From known to unknown.

Thank you
.Tinteresting that its qnx. worked with other RTOS?
CNo I haven’t worked with other RTOS yet.

Z@32bitSaviour
UIt seems like the automotive industry is preparing to adopt Rust. However, the author admits that Rust may not be suitable for early prototypes and certain use cases. I wonder what those use cases might be?
ZIn my experience Rust sucks if you have to do discovery or prototyping, this because you almost have to build the whole house of cards before it works. However, if you know exactly where you are going Rust is ok, I noticed that the earliest POC was in C then Rust came along, Also this is the 12 Volt non critical ECU so it seems there still is a bit of work to get to the mission critical stuff.
UI hope you're not referring to issues with Rust's tooling.
ZNo the tooling is great! just that compiler won't let you get by with things not done
Zwhich is usually what we do in protoyping, we hack stuff together, rust won't let you do that.
UI think I got your point now
AHey guys, I could use some career advice!
I'm currently in my second year of university studying Electronics and Communication, and I’ve been working with Arduino and microcontrollers since I was 14. Over the years, I’ve learned quite a bit about Arduino, AVR, STM32, ESP32, custom board design, Embedded C, register-level programming, and some IoT as well.
Right now, I’m trying to figure out what to specialize in so I can land a good job in the next two years. I’d love to work in a big MNC within the electronics industry or possibly join my dad’s instrumentation manufacturing business—or even start my own hardware company down the line.
I feel like I’ve got a good foundation in generalized electronics, but I’m not sure which area I should focus on next, especially considering current trends. What fields do you guys think would be best for me to master, given my background? I also feel like my early start gives me an edge compared to my classmates (most of them haven't even touched an Arduino), so I want to make sure I’m leveraging that advantage.
Thanks in advance for any advice!

ZBasically In C, you can quickly prototype a motor control application by directly accessing registers and using global variables, even cutting corners for speed. In Rust, strict rules like ownership and borrowing force you to handle memory safety upfront, slowing down development during prototyping.
SI want to buy an oscilloscope can someone suggest me one around $400-500
UHere's detailed post with the list, price, and specs (Low-cost but still excellent oscilloscopes for SOHO) I'm sure you'll find useful. Best wishes!
