Hello everyone,

 

I got a new netduino-mini and tried to connect it to an SD card break out and it excellently worked....

My question is :

has anyone tried to use a bitbang SPI instead of the standard MICROSOFT SPI ?

if so please let me know or share any links.

 

am developing a project that uses a netduino mini with an SD card and a W5100 ethernet module.

if no solutions where found i would use one SPI for multiple devices...(2 chip selects (one of them inverted))

that would be a solution i think ....

 

Thank you for your help

Using enable/select lines is the normal to do multiple devices.  The .NET code will even manage them and synchronize them with the othe signals. Here are a couple links that might help:

Enjoy.
