I want to access micro SD card on Logomatic V2 through SPI. SO that I can read/write files on micro SD card using my Arduino Uno & SD library. I have connected SPI interface from Logomatic board to Arduino as follow :
MOSI -> PIN 11 on Arduino Uno
MISO -> PIN 12 on Arduino Uno
SCK -> PIN 13 on Arduino Uno
CS -> PIN 4 on Arduino Uno
3.3V -> 3.3V on Arduino Uno
GND -> GND on Arduino Uno
But I'm unable to detect micro SD card. What's wrong here ?
Any help would be appreciated !
