Cant read socket registers from socket0

TCP/IP Chip W6100
1

Sending the following commands (represented as hexadicimal messages) after confirming the W6100 is indeed visible on the network via commands as mentioned in the datasheet on page 83.

0x000,0x0D,0x02 //Setting the socket0 mode register to UDP4

0x0114,0x0D,0x15 //Setting the socket0 port to 5000
0x0115,0x0D,0x88

0x0010, 0x0D, 0x01 //opening the socket0

Whenever i read adress 0x000 the device return nicely 0x02

Whenever i try to read the adresses 0x114 i get no data eventhough i written my bytes into the adresses.

Does anyone know why?

Hi,

your question is kind of not detailed enough.
I assume, that:
0x000, 0x0D,0x02
is:
offsetAddress, bankAddress, valueToBeWritten ?!

if your bank addres is 0x0D, then you access socket3, not socket0.

Also 5000 dec. is 0x1388, not 0x1588 (use windows calculator :wink: )

Which code you use reading the chip? Did u try reading the ID-registers to verify your read-function work properly?

Regards
