« on: November 10, 2016, 04:01:24 AM »
Hello,

I have some problems with the SD CARD in my module.
I am trying to load the program "bmp" for testing the display, but i have a problem eith the SD card.

init
Initializing SD card...failed!


The original code is......and i have this for Arduino Leonardo

#define sclk 13               #define sclk 13 
#define mosi 11             #define mosi 11
#define cs   5                 #define cs   5
#define rst  6                 #define rst  1
#define dc   4                 #define dc   0


#define SD_CS 10         #define SD_CS 8


also i tr¡ed to add this 2 lines in the setup:

 pinMode(SD_CS, OUTPUT);
  digitalWrite(SD_CS, HIGH);


but doesn't work!

The format of the SD is FAT32



Thanks.

Hi,

I just buy the NHD1.69 OLED for Arduino, but i Have the Arduino Leonardo, NOT UNO or mega.

What is the code or the wire conexion for this Arduino? I have tried with the code for Arduino UNO, but doesn't work.
