Hello,

I need to connect an ENC28j60 module to STM32 Discovery. As there is some peripherals on board uses SPI for communication, i dont know which is the free to use SPI. I hope the SPIs used by peripherals is not available for our use!

Please provide a code snippet showing the respective SPI.

Regards

Vishal

The board has manual and schematic, including a list of used pins, suggest you review those.

If there is a conflict you can always remove parts.

Try searching the forum - various people have posted Excel sheets showing the pin usage of various discovery boards...

''Please provide a code snippet showing the respective SPI''

Have you looked at the SPI examples provided by ST (included in the firmware library)?

Just download from www.st.com MicroXplorer, it has all Cortex M devices, with pinouts, and functions, so you can design your board and don't have any conflicts

''download from www.st.com MicroXplorer ... you can design your board and don't have any conflicts''

But he specifically stated that he's using a Discovery Board! So that's no help - is it?!
