I tested 3 ethernet shields:
- the basis ethernet shield W5100
- the SEEEDUINO ethernet shield based on W5200
- the arduino ethernet shield 2 based on W5500 (the best).
4 different boards have been necessary to make the test:
- arduino UNO
- arduino MEGA 2560
- arduino DUE
- arduino ATMEGAS clone DIY
The red crosses in the matrix indicate that it was impossible to have a communication (I don’t have found yet the trick).
I give you 3×4 sketches: 3 shields (W5100, W5200,W5500 ) for 4 boards. And the usefull libraries to communicate for each shield (3).
And the SCADA via advancedHMI to test the communication.
Step 2: Conclusion
It was a huge task to make these subnumeral tests and 2 of them have not been issued. I’m working on the problem.
Thanx to all interesting tutorial on the net.
