Drawing Bitmaps

There is a built in microSD card slot into the shield, and we can use that to load bitmap images! You will need a

microSD card formatted FAT16 or FAT32 (they almost always are by default).

Its really easy to draw bitmaps. We have a library for it, Adafruit_ImageReader, which can be installed through the

Arduino Library Manager (Sketch→Include Library→Manage Libraries…). Enter “imageread” in the search field and the

library is easy to spot:

With the library installed, let’s proceed by downloading this image of pretty flowers (pix by johngineer):

Copy purple.bmp into the base directory of a microSD card and insert it into the microSD socket in the shield. Now

upload the File→Examples→Adafruit_ImageReader→ShieldILI9341 example sketch to your Arduino + shield. You will

see the flowers appear!
