Hi guys, i am a final year undergrad student, Interested in embedded software, and the worst thing to happen to me recently was that i found out after a good 3 days of frustration, that one should be careful while choosing power supply for their project, a 100mV ripple can mess up internal circuitry of your sensors and you will keep wondering why sensor is generating nonstop garbage data.
Verdict - avoid cheap chinese stuff

Yes, but even if you can't avoid it, atleast have a good output filter circuit in place

Hello everyone,

I need career advice, I am MCA graduate and I have interest in embedded firmware development.

Can someone guide me?

Aditya thakekar•1/19/24, 5:22 AM

Only if you have interest... Start working around with small projects

Hi, @harsha3755 as Aditya said start with the project and build a portfolio. There is an easy path and another is a little hard. The easy way is to get into any IoT company and work on software dev and you'll get a chance to work closely with an embedded team and then start adding value with cross-functional skills. In any IoT job profile, you'll be dealing with h/w anyway. Another route is to pick a development board, understand OS, memory management in detail, and learn to write drivers for peripheral interfaces, take some internships that will focus on firmware. And you'll get the title embedded firmware. I hope this may help. Good luck and best wishes!

Just a suggestion for this, instead of hosting it here we can have our x (twitter) space where there is more chance of publicity and other can listen in too

Aditya thakekar•1/19/24, 5:39 AM

Right there are two major aspects.

If you have financial responsibility, always make sure you start in part time and work on your interests as an intern or just help people around as a side hustle.
If you genuinely love building Electronics project, and you wish to get a job in software or hardware, then approach a startup and work with them for atleast a year or two where you will learn a hard skill.
Build your soft skill in parallel. But always keep in mind, don't go behind any field just because grass is greener at the other end. Make sure you truly enjoy doing things. Else frustration builds up.

Another approach can be, as you are an MCA student you can use your frontend knowledge to go into interface development for embedded devices, and maybe develop software for Windows (visual studio) for testing ; Theses have high job opportunities in industrial embedded (electrical / mechanical )

In Bangalore

tahenan•1/19/24, 6:24 AM

Okay, I am sure there are many startups working is similar domain who would love to give you a start, do ask for incentive-based work

Yes, I will approach them in LinkedIn, thank you so much for the advice

Petr Dvořák•1/19/24, 6:43 AM

@kmulier Would it be possible to start a separate room/chat for the Scarab board? Here in the dev-chat there is a mess. I almost don't read the messages here. To your question. I recommend considering the 0402L020SL or even 010SL. I recommend to consider the average power consumption of the board and make a decision based on that value.

techielew•1/19/24, 6:54 AM

I actually asked if we should start another forum or chat channel for the Embeetle/DevHeads TinyScarab community development platform (featuring WCH RISC-V microcontroller and later RP2040). What do you think, guys?

A. Forum
B. Chat
C. Leave as is

Vote..

Navadeep•1/19/24, 7:27 AM

Yeah so much so. And this is of course not dev-chat. This is turning to be a welcome chat with mix of everything.

One thing to do is kick the DevHeads bot which keeps screaming about verification of new people to another space named #intro

Navadeep•1/19/24, 7:29 AM

I think there was one channel like that - doesn't seem to exist.
@Phoenix

Ffwen Whattt I've never seen a dev board this cheap let alone the Bluetooth capability

Navadeep•1/19/24, 7:39 AM

oh boiii. Just looked at their catalogue. Some awesomazing products. I am liking this one https://www.wch-ic.com/products/CH32V208.html?
not easy to get all this features in a package - perfect IoT MCU(has ethernet PHY and MAC within! gateway applications). Unsung hero of IoT MCU.

Umesh Lokhande•1/19/24, 9:31 AM

Hi @fwen agree with you. Sometimes even experienced people concerned about new tools especially unpopular ones. It leads to time investment and not getting the expected results causing delays in project delivery.

kristof-at-embeetle•1/19/24, 10:03 AM

@Navadeep , @fwen and @Umesh Lokhande ,
You guys said about the WCH chips:

I think it lacks some tool chains and tutorials right at the moment. That is making it harder for newer people to get into it.

We're solving that with Embeetle IDE [see https://embeetle.com] - not only for WCH chips of course, but for all the MCUs we integrate, we're not bound to a specific vendor. Here's what Embeetle can mean for you when you want to get started with a new MCU:

Embeetle provides one or more sample projects for your MCU, typically to blink an LED for a quick start.
Embeetle downloads all the tools automatically when you launch a project (compiler, flashtool, ...).
Embeetle provides excellent documentation on the MCU and the dev board, eg: https://embeetle.com/#supported-hardware/wch/boards/ch32v003f4p6-evt-r0-1v1

kristof-at-embeetle•1/19/24, 10:05 AM

Sorry for the shameless self promotion

kristof-at-embeetle•1/19/24, 10:05 AM

Anyway, Embeetle is free software.

fwen•1/19/24, 10:07 AM

I'll make sure to check it out if I get my hand on a WCH microcontroller.

kristof-at-embeetle•1/19/24, 10:09 AM

I can send you the Tiny Scarab board when it's finished and fully tested. I might have to ask a little compensation for the production costs. I'll share more on that later here in the chat (once I have a definitive production cost estimation).

fwen•1/19/24, 10:44 AM

This model took 3 hrs to print, 30mins of post processing and almost 2.5-3hrs to clean all the mess

Hello guys,

I wanted to know more about standardised architecture of linux based embedded system.

My system is having Digital IOs, Analog IOs, CAN, Modbus over RS485, RTC, Web server etc....

Hardware is ready. Also, it's working smoothly but i dont want it to be tightly coupled.

What i want is every other module will work independently and i will code the application (Custom logic) only as per requirement.

Any suggestions, posts, links.....i am relatively new to this.
Thank you...!!

abhishek awasthi•1/19/24, 7:50 PM

as the requirement you have provided ... i feel that all these input interrupts and outputs should have thier own logic and so some kind of ipc ... in that situation you can utilize some ipc methods or else you may use ros as an architect ... where everything is a pub sub structure and considered as nodes ...
