Bitmaps

There is a built in microSD card slot into the breakout, 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).

It's really easy to draw bitmaps! Let's start by downloading this image of purple flowers

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

Two more wires are required to interface with the onboard SD card:

You'll need to connect up the SO pin to the SPI MISO line on your microcontroller. On Arduino

Uno/Duemilanove/328-based, thats Digital 12. On Mega, its Digital 50 and on Leonardo/Due its ICSP-1 (See SPI

Connections for more details (https://adafru.it/d5h))

Also, the CCS or CC pin to Digital 4 on your Arduino as well. You can change this pin later, but stick with this for

now.
