For learning purpose i decided to write my own Ethernet drivers and at least get ip.
I picked up enc28j60
I got the driver working and i also was able to send arp request and it was seen in Wireshark as well
But i still cannot see my mac bound to ip in my router
I am using esp32 and enc28j60 sheild
Anyone wants to join me in this adventure are welcome

What is the optimal team size to design and deliver a high-profile initiative?

I worked at several companies, leading teams of various sizes (from 1 to 15 developers, depending on the initiative). Based on my experience, what matters is the seniority of a development team, not the headcount.

Various team sizes enforce different strategies and introduce versatile risks.

Based on your experience, what is the optimal number of senior developers working on a global-scale SaaS IoT platform backend?

That will be a smart parking system. Integrated fully, the solution points drivers to empty car parking spots in a mall or cinema or busy spots in the city where it is integrated.

Looking to integrate into existing apps like Google maps, so the drivers don't need to download any other app...it just pops up in your phone screen when you approach a building that has the solution

Marvee Amasi•5/13/24, 2:16 PM

Nice stuff, I would love to know much about how the system works , e.g , how does it detect empty parking spots , and how does it integrate with Google Maps to provide a seamless experience for drivers

Yes , i think just include the library by going to Sketch -> Include Library -> Manage Libraries.
Search for "String" or "Standard C++" and add it

What it's going to be about this week

wafa_ath•5/14/24, 5:56 PM

I found a great website that keeps your electrical work

clean and meets all international quality standards in electricity

This website includes:

Various tools and equipment used by electricians, with all their specifications.

Everything related to APIs and their datasheets.

Summaries of all the rules and fundamentals of motors and their control.

Various installations in industrial electricity and BTE.

Explanation of various electrical standards NF C.

And the best thing about it is that it has Excel sheets, guides, and customizable templates to help you with power balance and calculate the parameters you need for your electrical work.

So, share with us a website that helps you with your electrical work..

Hi everyone, anyone has experience with battery chargers, I have 38v one, and label says : charging voltage 48v, and now I'm confused wich charger I can use for it.. And How I can wire it to the battery?

onky•5/15/24, 9:57 AM

So I assume, you want design your own electronics.

onky•5/15/24, 2:00 PM

As per Nyquist criterion, your sampling frequency must be twice of measuring frequency, so your signal is 70 MHz, so fsample must be 140MHz, in this case you need ADC with 250Ms/s atleast, and depends on your measuring instrument memory you will have to transfer the measured data to larger memory multiple times in 16 mins as DSOs does not have large memory, this changes with resolution of ADC. Lower resolution lower data.

Hi Devs, I want to share with you my experiment today, so my friend wanted to print a pcb with the fastes way possible, with high quality, and we didn't want to use Ink and iron method, so I came up with thus idea, to cut adhesive warp with plotter machine and remove the excess then apply it to copper board then pure the solution... And this was the result,
what do you think about it
