How to make the SD card socket on the TFT LCD shield work with Arduino MEGA 256- DFRobot Forum

2014-05-12 23:04:06 Hi again orpheus88,
I've already try to format using the FAT32, it seems to be fine when the kit still connected with my computer but after i plugged in to the obd car the display on the LCD kit listed as "no sd card", still the same problem.

Can you share your program sir? many thanks before. DonJuan

But seems to be approved posting, which is probably why there are like no posts. orpheus88

2014-05-06 03:34:22 In another forum stanley wrote you should use FAT32 and thats also what my cards, that work in the Freematics adapter, are formated with. orpheus88

2014-05-05 21:23:36 Hello tomansbro,

I wanna ask about the format, what format are you using? FAT16? FAT32?
I've tried with the FAT16, and it works fine at the first it can tell how much space the memory left, but after i plugged in to the obd connector in the car, it shows up "NO FAT" result.

Any info or help about that please. DonJuan

I Will try it.

2014-02-12 15:26:24 After lots of trial and error, I decided to try on a new machine. Success!! apparently my libraries were corrupt.
Back to the first machine, uninstalled EVERYTHING, reinstalled IDE & Libraries and JOY!! working as designed. tomansbro

2014-01-31 07:05:47 Thank you Stanley,
After reinstalling IDE and Libraries the sketch compiles with no errors. I have edited config.h and Sd2card.h as posted in the FAQ. but still no Joy.. NO SD CARD ....the card is formatted as fat 32 I tried another one formatted as Fat...What else can I try?
Thanks for all your help!

2014-01-28 17:16:36 Go to <Arduino Dir>/libraries/SD/utility, open Sd2Card.h file, find and uncomment following line:

#define MEGA_SOFT_SPI 1
My Sd2Card.h file has #define MEGA_SOFT_SPI 0
If I change the 0 to 1 I get the error
C:\ Program files\arduino...\utility\Sd2card.cpp:585: error: 'SPI' was not declared in this scope
what am I doing wrong?
