I have five sensors. Can I transfer their readings from the Arduino to the ESP32 via UART or do I need level shift?

Umesh Lokhande•10/2/24, 12:31 PM

Since they operate on different voltage level, the best way to use level converter or else you can bring the voltage of arduino to 3.3V. This can be done by a voltage divider circuit using one 10k resistors and one 20k resistor at Tx Pin of Arduino.

Abdullah•10/2/24, 12:53 PM

Do you mean like this?

Abdullah•10/2/24, 12:53 PM

Or how ?

AAbdullah Do you mean like this?

Umesh Lokhande•10/2/24, 1:55 PM

yes, try and test with these connections

Abdullah•10/2/24, 8:13 PM

What is the best type of ESP32 in terms of voltage reading accuracy from analog pins because I have an ESP32 but the reading accuracy is not stable or close. It rises and falls at high degrees of more than 500 bits up and down and is also not stable. For example, it rises to 1700 and drops to 1432 and rises to 1520 and drops to 1300. What is the solution?

You could have an external voltage sensor
Or maybe look at how bits the ADC is

you can improve ADC's accuracy using reference voltage. Here is how to do it https://www.youtube.com/watch?v=mzlq65fr3uI

Abdullah•10/4/24, 5:31 PM

Does this piece fully stabilize the readings in the esp32 or is it useless?

Is there a difference between these two in terms of the accuracy of the readings or is it just the size?

nour_oud•10/5/24, 1:32 PM

Welcome back! How’s the AI integration into Embeetle going so far? Have you had success with running the LLM locally?

kristof-at-embeetle•10/5/24, 2:04 PM

Yeah

kristof-at-embeetle•10/5/24, 2:04 PM

As you can see in the video, it is a success

kristof-at-embeetle•10/5/24, 2:04 PM

You can select from 15 online and 34 (!) offline models.

kristof-at-embeetle•10/5/24, 2:05 PM

The offline models need to be downloaded just once. Then you could plug out your internet connection if you wish so.

kristof-at-embeetle•10/5/24, 2:05 PM

Ideal for security

kristof-at-embeetle•10/5/24, 2:06 PM

But, I must admit that the local models are a bit slow. The online ones are much faster in responding.

kristof-at-embeetle•10/5/24, 2:06 PM

Feel free to give it a try!

Marvee Amasi•10/5/24, 2:18 PM

I recently ran into a tricky memory access violation on x86 64 that wasn't easy to catch with gdb. Switching to Intel's VTune gave me deeper insight into cache misses and pipeline stalls, which made all the difference. In lighter cases, I’ve also used perf to track CPU usage spikes and lock contention across cores.

What tools or methods do you rely on for debugging low level issues on x86 64? Have tools like perf, gdb, or VTune been particularly helpful for you in diagnosing hardware specific issues ?

techielewOP•10/5/24, 2:42 PM

I'm curious about the development process/experience and what sort of accuracy/consistency you're seeing with it?

kristof-at-embeetle•10/5/24, 3:05 PM

There are 49 AI models to choose from
