4Designed for the DSD
5  Tech 1.8" TFT screen and Adafruit drivers
6To allow simultaneous screen and card
7  reader functions,
8use hardware SPI, not software SPI
9(although pins 8 and
10  9 can be swapped)
11The pin breakout DSD Tech 1.8" TFT screen is as follows:
12
13  VCC........5V
14 GND........GND
15 GND........
16 NC.........
17 NC.........
18
19  NC.........
20 CLK........13 (or SCK)
21 SDA........11 (or MOSI)
22 RS.........9
23  (or DC)
24 RST........8  (or RESET)
25 CS.........10 (or SS)
26Solder a four-pin
27  header to the SD connections on 
28the DSD Tech 1.8" TFT screen
29 SD_MISO....12
30
31  SD_SCK.....13 (connected to screen CLK above)
32 SD_MOSI....11 (connected to screen
33  MOSI above)
34 SD_CS......4
35The SD card will work if it is 2G or less and formatted
36  as FAT (FAT16)
37To fit on the screen, all image files on the card must be pre-sized
38  
39to 160 by 128 pixels or less and must be 24-bit RGB BMPs
40The BMP file names
41  must be no longer than 8 characters, 
42however, when using many BMP files, the
43  file names will eat up memory,
44so use two-letter names
