I am using wiznet w500 io module purchased from ebay . I am interfacing with arduiono atmega2560 . WHEN I CONNECT THE MODULE windows xp show connected and both led are ok and also one of led start blinking but stop blinking after some time it stop blinking . ping is not working is module is damged or some thing esle as arduiono code show sever at 0.0.0.0 i am using latestes arduion libary.
my connection as follwo
MISO → MISO
MOSI ->MOSI
CS > LOW TIED TO GROUND
RESTET LEFT ALONE
SCK → SCK
WHAT IS PROBLEM
Hi
Sorry to late your answer
you checking the W5500 datasheet.
And I need you code.
you using arduino example code?
there is 3 fact.
First, module broken. → This problem is probably not
Second, you connected LAN port ? and you check link LED blink?
third, SPI signal matching is wrong. check to below code. below code is SPI each signal part matching code
// CLK pin enable
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; // External clock
//MISO pin enable
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; // Master in Slave out -> Floating = high Impedence
//MOSI pin enable
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; // Master Out Slave in (Slave is external)
//CS pin enable
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; // GPIO_Mode_Out_OD - open drain (open collect) -> It's want Pull up resistor
//RESET pin enable
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; // M3 (Master) -> W5500 (Slave)
//INT pin enable
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU; // internal Pull up
Thank you
