I use:
Arduino Mega 2560
TFT LCD Mega Shield V2.2
3.2" TFT LCD 320x240with SD card socket
I want to read/write "file.txt" from SD card (SD card on card socket of 3.2" TFT LCD )
I saw some topic and forum, but i not found the way to do it, help me
You need to check the relevant data sheets, and be more forthcoming on your code and equipment.
My 400x240 has the SD on the shield, and I had to bridge a pair of solder pads in order to use it. I understand yours is on the display but you may have to do a similar trick somewhere, most likely on the shield. I also had to change the chip select from the usual 4 to 53. This is in addition to the usual command
pinMode(53, OUTPUT);
required on the Mega. I believe both commands relevant to pin53 are required. This applies to the standard SD CardInfo example.
hi friends i have tha same problem ,,,, need to read / write from SD .... did you solve it ???
