 Posted: Thu Dec 15, 2022 4:01 pm Post subject: W5500 Network status |
 |
|
Something I can not find in the documentation or online;
Is there a simple way to check the actual PHY connection status? For example the Link status?
Because when I boot a W5500 without a network connected it can not build a propper network connection. (Not alway's)
Checking for the socketstat <> &H17 does not always help out I noticed.
For arduino (C coded) I found several sollutions, but within easyTCP I could not. |

then port this code.
or read the W5500 PDF. i think the register is documented that holds the status and you only need to read this register value. there are statements/functions to read/write registers in the W5500

Hi Albert, see below.
The W5500 registers indeed hold a status that I will check.
never the less, I was wondering if there was a shortcut within easytcp, bu I guess there is not.
chears!
| Code: |
Do
Status = Socketstat(idy , 0) 'port status
Waitms 50
incr fail_count
If Status = &H17 Then '&H17 is a TCP connection
fail_count = 0
returnbit = 2
Exit Do
Elseif fail_count = 200 Or Status = &H1C Then
Socketdisconnect Idy
fail_count = 0
returnbit = 1
modeselected = 1
Waitms 50
Goto main
End If
Loop

it does not make sense to make a function for each bit since you can use the Gettcpregs function to read any register.
the PHYCFGR register is what you are after, bit 0 contains the link status.
