Hello all.
First of all, I'm new to the forum and also with Arduino.
For my project I need to get this Arduino to show pictures from sd card.
My hardware setting are currently
Arduino mega 2560 from Robotale
TFT_320QVT
TFT LCD Mega Shield v2.2
I have 2 sd cards. Elite pro 8gb i ordered with mega and old kingston 1gb
I got the lcd screen working just by plugging it over shield and using Henning's UTFT library demo 320x240. I could also draw pixels etc so tft is fine.
Formated the sd cards with SDformatter v.4 which was suggested at many sites. Both says FAT32 when checked in windows 8.1
Downloaded the newest SdFat library from Fatlib16 yesterdays post and run the QuickStart.
Results: (tried all suggested pins, 4,8,10,53 with spi enabled and disabled and both cards, quarter full and half speeds.)
SPI pins:
MOSI: 51
MISO: 50
SCK: 52
SD chip select is the key hardware option.
Common values are:
Arduino Ethernet shield, pin 4
Sparkfun SD shield, pin 8
Adafruit SD shields and modules, pin 10
Enter the chip select pin number: 53
Disabling SPI device on pin 10
Card successfully initialized.
Card size: 1074 MB (MB = 1,000,000 bytes)
Can't read the card.
Try another SD card or reduce the SPI bus speed.
Edit spiSpeed in this sketch to change it.
Restarting
Enter the chip select pin number:
I have also earlier tried Adafruit Sdinfo and it recognized the kingston card as SD1 and elite pro as SD2. But couldn't find FAT16/FAT32 partition.
I've also tried to use 9v battery as power source, cause someone suggested that.
I'm really out of options and asking for help!
If you need more information, just ask!
