# Parallel bus mode example

## Question

Asked by erenaud on 2022-01-05 in Ethernet Chips.

Hi all,

I got my W5100S working with SPI mode and now I would like to try parallel bus mode.

It is very easy to find some SPI examples but I haven’t found anything for parallel bus.

Would anyone have some available example ?

Thanks

Looks like I haven’t search enough…

[This github link (EVB 5100S code)](https://github.com/WIZnet-ioLibrary/W5x00_Loopback_with_W5100S_EVB/tree/master/Eclipse/W5100S_loopback/W5100S_Loopback) show how to use parallel bus along with FSMC for anyone looking for an example.

Hello.

Unfortunately, there is no example of parallel bus mode.
An example of a single SPI mode bus is on Wiznet Github.
