SPI to LAN interface using ATmega16

[gayatri dandekar]

I am working on a new project and I need to interface SPI with LAN using ATmega16.

 

I am new with AVR and I have very minimum idea. I need some guidelines to start with.

 

 

Please help.

Hi Gayatri,

“interface SPI with LAN”, could you please share more details.

Hi Alfred,

 

I need to establish a connection with ATmega16 and ethernet. I just don’t know whether it can be done directly.

Is there any module available that can directly be interfaced with AVR through SPI.

I suggest to use Wiznet W5100 ethernet module. It is widely used as ethernet interface in most of the development boards. The best part is that this module has built in TCP/IP layers and hence you can reduce the complexity of the code. Just download the datasheet from wiznet and you have all the details including sample codes.

Thank you very much. The information you provided was very helpful.

 

 

Thanks once again

You are welcome Gayathri. It is really interesting project and if you face any issues with it please feel free to share with us.

i would suggest ENC28J60 chip…..you can buy the module also.. it is developed by Microchip and can be interfaced with 8051, AVR or PICs…It even comes in a module…which removes your complexity..it has projected pins for above microcontrollers..
