49 / 100 page  ST7530 Ver 1.8 49/100 2006/9/18 PB2 is to change RGB arrangement of the segment output according to RGB arrangement on the LCD panel. This command will set the writing position of data(R, G, B) on the display memory to be changed or not. Stripe mode: CLR SEG0 SEG1 SEG2 SEG3 SEG4 SEG5 SEG6 SEG7 … SEG254 0 R G B R G B R G … R 1 B G R B G R B G … B SPRD C mode: CLR Line SEG0 SEG1 SEG2 SEG3 SEG4 SEG5 SEG6 SEG7 … SEG255 0 0, 2, 4, … 1, 3, 5, … R G G B B R R G G B B R R G G B … … R G 1 0, 2, 4, … 1, 3, 5, … B R G B R G B R G B R G B R G B … … B R PB3 is to select desired display colors between the 32 gray-scale dithered 65K, 262K, or 16M. GS2 GS1 GS0 Numbers of gray-scale 0 0 1 32 gray-scale 65K 0 1 0 32 gray-scale 262K 1 0 0 32 gray-scale 16M (12) Memory write (RAMWR) - Parameter Byte: Numbers of data written (5CH) This command turns on the data entry mode when MPU writes data to the display memory. This command will always sets the line and column address at the start address while executed. The following parameter byte rewrites contents of the display data RAM and increases the line or column address automatically. The write mode is automatically cancelled if any other command is entered. 1. 8-bit bus A0 RD RW D7 D6 D5 D4 D3 D2 D1 D0 Function Command 0 1 0 0 1 0 1 1 1 0 0 － Parameter Byte 1 (PB1) 1 1 0 Data to be written Data to be written 2. 16-bit bus A0 RD RW D15 D14 … D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Function Command 0 1 0 * * … * * 0 1 0 1 1 1 0 0 Memory write Parameter Byte 1 (PB1) 1 1 0 Data to be written Write date (13) Memory read (RAMRD) - Parameter Byte: Numbers of data read (5DH) This command turns on the data read mode when MPU read data from the display memory. This command will always sets the line and column address at the start address while executed. The contents of the display data RAM will be read in the following parameter byte and increases the line or column address automatically. The data read mode is automatically cancelled if any other command is entered. 1. 8-bit bus A0 RD RW D7 D6 D5 D4 D3 D2 D1 D0 Function Command 0 1 0 0 1 0 1 1 1 0 1 -- Parameter Byte 1 (PB1) 1 0 1 Data to be read Data to be read |
