EXAMPLES
EXAMPLE B-1:
This example clears the display and writes “Hi” starting at row 2, column 10. Write the
following bytes to the SPI port:
0x82
0xE7, ‘H’, 10, 2
0xA8, ‘i’
EXAMPLE B-2:
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
0xDA, 119, 31
EXAMPLE B-3:
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
0xBC, 0x01
0xBC, 0xFF
0xBC, 0x01
Advance Information
// Clear screen
// Write ‘i’ at column 11, row 2 then increment the column
// Set Pixel cursor to X=1, Y=1
// Draw line to X=119, Y=31
// Set Column cursor to X=19, Row = 1
// Write pixel at top of display at column 19, increment column
// Write vertical line at column 20, increment column
// Write pixel at top of display at column 21, increment column
WRITE A WORD
// Write ‘H’ to column 10, row 2, then increment the column
