Need your help, I just realized that I need to use the attach sd card reader from my TFT LCD Screen since i will use a lot of images that will consume more memory in my arduino mega. My problem is when I inserted the sd card which is tested working in my phone , I cannot successful loadbitmaps from it . What library should I use to know if my sd card was read by module and well functioning ? thanks for your reply
I am using mcufriend 3.5 inch tft LCD 320X480...
