Using external SPI SDCard
|
||||
-------------------------
|
||||
It is possible to use external SDCard over SPI with the
|
||||
nucleo-stm32l476rg Cortex-M4. This option will or can broaden the
|
||||
functionality in your project, solution or application.
|
||||
|
||||
In this Nuttx project we attach an MH-SD Card Module (SPI).
|
||||
[http://www.geeetech.com/wiki/index.php/Arduino_SD_card_Module]
|
||||
|
||||
Other solutions should also work.
