Power supply connection diagram 5-4. Logic block diagram The LCD module needs power sources: Vdd for logic Note: It is necessary to guard all signals from external noise as signal lines are directly connected to C-MOS and are not pull-up or pull-down internally. 7 Dalian Dongfu Color Display Co., Ltd.. User’s Manual 8 Dalian Dongfu Color Display Co., Ltd.. 5-5. Description for software and hardware 5-5-1. The internal structure of module From the above diagram, we may find that the module is mainly composed of LCD panel, controllers and segment drivers. The control circuit mainly consists of Instruction Register (IR), Data Register (DR), Busy Flag (BF), Display On/Off flip-flop (DFF) and XY Counter. ● Instruction Register (IR) IR stores instruction code. When D/I=0, the instruction is written into IR on the falling edge of E. ● Data Register (DR) DR stores data. When DR=1, graphic display data are written into DR or are read into DB7 to DB0 data buses under the action of E. The data transfer between DR and DDRAM are executed by internal operation automatically. ● Busy Flag (BF) Busy flag indicates that the module is operating or not operating. When BF=1, the module is in the internal operation and does not receive any external instruction and data. When BF=0, the module is in the ready status and can accept the data or instruction at any time. ● Display on/off flip-flop (DFF) The display on/off flip-flop makes on/off the liquid crystal display. When DFF=1, display on. The contents of DDRAM are on the screen. When DFF=0, display off. ● XY address counter XY address counter is a 9-bit counter. X address counter is higher 3 bits. Y address counter is lower 6 bits. In fact, XY address counter is used as the address pointer of DDRAM. X address counter is page address pointer of DDRAM. Y address counter is Y address pointer of DDRAM. ● Display Data RAM (DDRAM) DDRAM stores a display data for liquid crystal display. To express on state dot matrix of liquid crystal display, write data 1. The other way, off state writes 0. (See also DDRAM Address Table for the relation between the DDRAM address and the display position) ● Z Address Counter Z address counter is a 6-bit counter. It has cycle-count function, which is used to display with synchronous column scanning. When one column scanning is completed, the address counter is increased by 1 automatically and points to the next column scanning data. After reset, Z address counter is 0. Z address counter can be preset by DISPLAY START LINE instruction. Therefore, the display start line is controlled by this instruction. That is to say, where the DDRAM data start is the first line on the screen. There are 64 lines in DDRAM, which can be cycle-displayed on the screen. 5-5-2 Control instructions 1. Display ON/OFF R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 1 1 1 1 1 D D=1 DISPLAY ON D=0 DISPLAY OFF. Internal status and display RAM data is not affected. When the value of D is changed from 0 into 1, the former display is on the screen. 2. Display Start Line R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 1 A5 A4 A3 A2 A1 A0 User’s Manual 9 Dalian Dongfu Color Display Co., Ltd.. As explained above in Z address counter, the display start line is controlled by Z address counter. A5~A0 are automatically put into Z address counter. The address of start line can be any line of line 0 to line 63. For example: A5~A0 is selected 62, and the correspondence of the first line and DDRAM column is as follows: DD RAM Column: 62 63 0 1 2 3 ………… 60 61 Display column on the screen: 1 2 3 4 5 6 ………… 63 64 3. Set Page ( X ADDRESS ) Ｒ/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 0 1 1 1 A2 A1 A0 Page address is line address of DDRAM. There are 8 lines in one page. There are 64 lines in DDRAM (8 pages). A2~A0 represent page 0 to page 7. Read/write data does not affect page address. Page address is changed by this instruction or RST signal. After reset, page address is 0. See also the address table for correspondence of page address and DDRAM. 4. Set Y Address R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 1 A5 A4 A3 A2 A1 A0 The function of this instruction is to send A5~A0 to Y address counter. They are used as Y address pointer of DDRAM. Y address pointer is automatically incremented by 1 and points to the next unit of DDRAM after write/read is made to DDRAM. Table 4-4 DDRAM Address Table CS1=1, CS2=0 CS1=0, CS2=1 Y= 0 1 2 3 .. 062 63 0 1 2 3 .. 62 63 Line No. X=0 DB0 DB0 ↓ ↓ DB7 DB7 DB0 DB0 ↓ ↓ DB7 DB7 0 ↓ 7 ↓ DB0 DB0 ↓ ↓ DB7 DB7 DB0 DB0 ↓ ↓ DB7 DB7 8 ↓ 55 X=7 DB0 DB0 ↓ ↓ DB7 DB7 DB0 DB0 ↓ ↓ DB7 DB7 56 ↓ 63 5. STATUS READ R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 0 BF 0 ON/OFF RST 0 0 0 0 When R/W=1 and D/I=0, status read is output into the corresponding bits of data buses (DB7~DB0) (E in “H” level). BF: (See also BF part) ON/OFF: It means the status of Display On/Off flip-flop (See also Display On/Off flip-flop part) RST: When RST=1, it indicates that the system are in the initialization and any instruction and data except status read may not be accepted. 6. Write Display Data R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 1 D7 D6 D5 D4 D3 D2 D1 D0 D7-D0 is display data. This instruction writes 8-bit data (D7-D0) into D7-D0 to the corresponding units of DDRAM. The Y address is incremented by 1 automatically. 7. Read Display Data R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 1 D7 D6 D5 D4 D3 D2 D1 D0 User’s Manual Reads out 8-bit data (D7~D0) from the DD RAM. Then Y address is increased by 1 automatically. The instruction reads out the contents of DDRAM (D7-D0) to the data buses D7-D0. The Y address is incremented by 1 automatically Note: After the setting of DDRAM address, the dummy read is made at the time of reading data. 5-5-3 Method of interfacing module to MPU The interface circuit is as follows: The data bus P0 of 8031 is directly connected to the data bus of module. RD and WR of 8031 act as read/write control signal, interfaced to E signal terminal of module by NAND gate. 5-5-4.
