techielew•3/6/24, 6:03 PM

Nice. You've used? Which RTOS for which micro? And what are some of the common challenges you think we should address?

Aditya thakekarOP•3/6/24, 6:11 PM

ESP-IDF has both features so we don't have to separely use free rtos.

Aditya thakekarOP•3/6/24, 6:12 PM

BLE mesh runs on zephyr.. So they have combined both the features.

Hey, i use FreeRTOS (ESP IDF flavour) on ESP32

techielew•3/6/24, 6:48 PM

Nice! Are there any specific issues you encountered or could use help on? We're building a curriculum around it and wanting to address the most common issues devs encounter with it.

How do I choose the right RTOS for a security project?

Ttechielew What FPGA?

pemcilwarrior12•3/6/24, 10:36 PM

Lol

pemcilwarrior12•3/6/24, 10:36 PM

I m new here so

pemcilwarrior12•3/6/24, 10:36 PM

I m just wondering if there is someone here working on a smart glove project ?

Ppemcilwarrior12 Helloo

techielew•3/6/24, 11:58 PM

Hey @pemcilwarrior12, welcome! First, are you talking about the Open UK Project? I just had a conversation about that with someone this morning. Weird. Let me know if that's what you're referring to and I'll see if I can put you in touch.

#2. What's your technical background?!

pemcilwarrior12•3/7/24, 12:04 AM

Well let me explain my project :
I m going to make a smart glove for deaf and dumb people which translates sign language to text and speech using machine learning algorithms

pemcilwarrior12•3/7/24, 12:05 AM

I m using 5 flex sensors , an arduino and a raspberry pi 4 model B

pemcilwarrior12•3/7/24, 12:05 AM

And of course Lcd display and speakers

techielew•3/7/24, 12:06 AM

That's cool. Well, I can tell you I haven't heard of anyone specifically working on that but do you need specific help or have specific questions? There's plenty of expertise in server.

pemcilwarrior12•3/7/24, 12:07 AM

Thank you so much

pemcilwarrior12•3/7/24, 12:08 AM

Well , I m just wondering if there are some people here who are working on the same project for the moment

pemcilwarrior12•3/7/24, 12:08 AM

Or maybe someone can give me instructions about it

Do you have any documentation? Is this it (or similar)?https://www.eurchembull.com/uploads/paper/99a52e92f57b2fd4a75539a0dc8fa1fb.pdf

techielew•3/7/24, 1:53 AM

Okay, y'all. We're double-dipping on polls this week. The first is on your IoT communications protocols of choice: https://discord.com/channels/1130679493799977062/1199293807737450538/1214929045578326046

The second is the 'technical info' poll I said would be coming. How do you get your tech info/education:
https://discord.com/channels/1130679493799977062/1199293807737450538/1215087672759160845

You can find that and results from other polls in #polls.

techielew•3/7/24, 8:13 AM

Ha, well if that's the case check out the build server where you can customize your fimware: https://custom.ardupilot.org/. You should be able to strip out a significant amount to get under 1 MB, which will open your options.

Or you can just go through the list here: and see what the cheapest board is.

ArduPilot

ArduPilot Custom Firmware Builder

ArduPilot Custom Firmware Builder. It allows to build custom ArduPilot firmware by selecting the wanted features.

Aditya thakekarOP•3/7/24, 9:26 AM

Great. You can. For display you can just you print statements. And work on webscokets. Later you can add all the displays

Wwafa_ath I am using Knowles SPH0641LU4H-1 🎤 and yes it is i2c

Navadeep•3/7/24, 9:42 AM

Yeah, this part looks good. It has PDM output as well. Check out this blog https://community.element14.com/challenges-projects/design-challenges/pathprogrammable3/b/blog/posts/p2p3-amd-vivado-cascaded-integrator-comb-cic-compiler-pdm-microphone-to-pcm-decimation
