Hi all, I have a Winform App [VB.net] get frequence number from many devices and stored them on MS SQL. Now, I need a solution to display this number on Ledmatrix by realtime using ethernet.
For this lab, Im using: arduino UNO, Ethernet shield, 8x32 Ledmatrix Max7219.
Please help. Thank you.
I suggest you use Google to find similar projects others have done. This will give you ideas for circuit and code.
Thank you, but I had been searched every thing on Internet before asked. And almost them is use Ethernet board as a webserver to controll text. It maybe spend a ton of time to get familiar with web, http ....
My idea is push the plan text to Arduino using Udp, and display it to LED. it can recieve data but can not display it.
I hope find another idear without using webserver T.T
I think using UDP versus HTTP will be about the same level of difficulty.
Break the problem down. Get some fixed text scrolling on the display. Then get your remote client to send some fixed text to the Arduino. Then combine the two sketches. Then you can work on how get the data from your database sent to the Arduino.
What system does the ms SQL database run on?
The internet is vast. You cannot have "searched every thing". You may not have chosen the best search terms, or you are looking for something too close to what you want. Look for similar projects that have one or more features in common with your own project.

I would bet Microsoft Windows Some version.
MySQL is now owned by Oracle
MariaDB is now the opensource replacement for MySQL
MSQL died long ago.

Móa, có ai nói dùm tui là thằng chả này chỉ là "ếch ngồi đáy giếng" không ?
@PaulRB : I suggest you use Google to find what is MS SQL . This will show you the vastly of internet.

Please remember that you came here for help, not the other way around. I am not interested in ms SQL and I will not spend my time doing your research. Please read the forum guidelines. They will give you advice about how to get excellent help from this forum. Right now, you are doing the opposite.

You are not going to get any help if you continue to post in Vietnamese .
Paul, has given you suggestions.
We here are not going to program nor solve the school lab for you.
