5 / 10 page www.vishay.com 45 APD-240G064 Vishay Dale Document Number: 37046 Revision 21-Dec-00 COMMAND SET, GRAPHIC MODE (SOFTWARE INSTRUCTIONS) CURSOR LOCATION - All cursor locations are based upon Pixel location - NOT - character column and row locations. The upper left hand corner is 000,000 (X, Y) while the lower right hand corner is 239, 063 (X, Y). The cursor auto-increments based upon the character font size by the width of the font. The cursor is not visible in graphic mode. WRITE LOGIC - Within most commands, the WRITE LOGIC byte must be included: 0 = SET PIXELS (turn-on foreground pixels) 1 = XOR PIXELS (invert foreground pixels) 2 = RESET PIXELS (turn-off foreground pixels) 3 = OVERWRITE (turn-on foreground and turn-off background pixels, image load and graphic text commands only) FONT SIZE The FONT SIZE must be written before text is written. There are three standard fonts included in the graphics mode: 1 = FONT 1, a 4 x 5 character in a 5 x 6 block 2 = FONT 2, a 5 x 7 character in a 6 x 8 block 3 = FONT 3, a 10 x 14 character in a 12 x 16 block Refer to character set tables for supported characters and fonts. Note: The LOGIC byte and FONT byte are sent in ASCII format. DATA FORMAT All addresses must be sent in ASCII format. Column and row positions begin at the upper left hand corner at address 000,000 (X, Y). A pixel address consists of a column address followed by row address. Addresses are sent to the panel as a three character ASCII sequence for column (x) followed by a three character ASCII sequence for row (y). An example is the upper left hand pixel is 000,000 while the lower right hand corner is 239, 063. Note: Spaces are shown in the graphic sequences only for clarity and must not occur in the actual commands transmitted to the panel. GRAPHIC FUNCTIONS GRAPHIC FUNCTIONS CLEAR SCREEN: This command will clear the graphic screen to all pixels off (logic 0). ESC C TEXT WRITE: Logic byte (l), font byte (f), x, y starting address, ASCII text. Wrap around will occur. ESC B l f xxx yyy aaaa..aaaa ESC \ SET PIXEL COMMAND: Logic byte (l), x, y pixel address, end of data delimiter. ESC D l xxx yyy ESC \ (Single pixel) ESC D l xxx yyy xxx yyy .......ESC \ (Continous) SET GRAPHICS MODE: ESC G DRAW ELLIPSE: Logic byte, major axis intercept offset, minor axis intercept offset (axis's intercept offset is measured in pixels from the center point), x, y center point, from angle theta (t), in degrees, to phi (p). A complete rotation would be from 001 to 360. ESC H l mmm www xxx yyy ttt ppp WRITE GRAPHIC IMAGE: Logic byte 1, y1 (upper left hand corner), 2, y2 (width and height), data. ESC I l xxx yyy xxx yyy ddd .... X1 start coordinate and X2 width must both be multiples of 8. The number of data bytes transmitted must be equal to (X2 width / 8)* Y2 height. The first data byte transmitted will map into the 8 pixels on the top line in the upper left hand corner of the image with the least significant bit at the left and the most significant bit at the right. Successive bytes will write to the next byte to the right. When all bytes are written for this line, the next byte will map into the left most byte of the next line down. Graphical representation of each data byte: lsb x x x x x x msb HEX CODE 1B, 42 1B, 43 1B, 44 1B, 46 SET TEXT MODE: ESC F 1B, 47 1B, 48 1B, 49 |
