Welcome DNS, what brings you to DevHeads?

Abdullah•9/30/24, 9:51 PM

Can I send data for two sensors with two variables from Arduino to ESP32 so that the value of each sensor appears in a different variable in ESP32?

I'm glad you brought up SAST/DAST in the context of complacent development as I was going to say, "the static analysis tool will catch it!"

That's probably a danger regardless. You're either thorough or you aren't. No language is going to prevent buggy code/bad coding practices.

Hi! I stumbled upon this server on disboard. I am but an average electrical engineering graduate who got interested in embedded systems and systems programming, and now trying to self-learn. Currently learning programming on STM32

"No language is gonna prevent bugs/bad coding practices" I do generally agree, but I think that is an oversimplification. It's like saying "no driving style is safe on the road"

Please elaborate... If I drive drunk it doesn't matter if I'm in a tank or not I'm still not going to drive well and am much more likely to get in an accident.

If I'm in an auto-piloted taxi, then am I really driving?

barafael•10/1/24, 5:12 PM

The driving style is the language. Yes accidents happen even for very conservative drivers, but it just isn't the same likelihood. Not a perfect analogy. But saying the tool doesn't matter is papering over the details

No language or tool offers you auto-pilotauto-pilot even with the safe languagessafe languages stuff will still happen.

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 ?

Abdullah•10/2/24, 12:55 PM

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?

melta101•10/3/24, 2:17 AM

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?

Yes, it helps improves ESP32 analog reading stability and accuracy

Wwafa_ath Yes, it helps improves ESP32 analog reading stability and accuracy

Abdullah•10/4/24, 10:02 PM

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