B.8 EXAMPLES
EXAMPLE B-1: WRITE A WORD
This example clears the display and writes “Hi” starting at row 2, column 10. Write the
following bytes to the SPI port:
0x82 // Clear screen
0xE7, ‘H’, 10, 2 // Write ‘H’ to column 10, row 2, then increment the column
0xA8, ‘i’ // Write ‘i’ at column 11, row 2 then increment the column
EXAMPLE B-2: DRAW A STRAIGHT LINE
This example draws a straight line from X location (1,1) to Y location (119,3). Write the
following bytes to SPI port:
0xD7, 1, 1 // Set Pixel cursor to X=1, Y=1
0xDA, 119, 31 // Draw line to X=119, Y=31
EXAMPLE B-3: DRAW AN ICON
This example draws an icon 8 pixels tall and 3 pixels wide that looks like a ‘T’ on
row = 1, column = 19. Write the following bytes to SPI port:
0xDB, 19, 1 // Set Column cursor to X=19, Row = 1
0xBC, 0x01 // Write pixel at top of display at column 19, increment column
0xBC, 0xFF // Write vertical line at column 20, increment column
0xBC, 0x01 // Write pixel at top of display at column 21, increment column
