唔好只做cd-rom,  come and join the world, 唔好話:;不是原創;人地都造過;好簡單;要好多錢;要好多時間;唔識做;唔知點做;沒人教;.........,
不要一步登天,不要天才,不要高難度,不要十全十美.

只要你!

Setting 'PARALLEL EQU 1' enable parallel operation ( 'J1'  to 'VCC' ),
Setting 'PARRALE EQU 0' enable serial operation ( 'J1'  to 'GND' ).

問對應port....

LCD_RD                即是RW_WR?
LCD_WR               唔知是那個
LCD_RS                即是A0(RS)?
LCD_RESET          即是RES?
LCD_CS                即是CS

另有關寫Control這段,LCD_WR 的部份我應該看那張時序圖?P.15 的External Signals和Internal Signals我看不明
LCD_DATA:
        NOP                 
        SETB LCD_RS      
LCD_WR_CODE:
        CLR LCD_CS      

;**************************************************
IF (PARALLEL)
        SETB LCD_RD      
        MOV LCD_DATA_BUS,A      
        CLR LCD_WR      
        NOP                 
        SETB LCD_WR


LCD BIAS SELECT又會影響甚麼?
Duty Ratio ,Duty 1, Duty 0 又如何控制?

LCD_RESET is RES (the reset pin)
LCD_CS is CS (the Chip Select pin)
LCD_RS is the RS (Register Select i.e. A0)

For the two other pins:
If pin 3 of the lcd is connected to GND, you are using 8080 interface, then
the two pins are defined as RD and WR.
If pin 3 of the lcd is connected to Vdd, you are using 6800 interface, then
the two pins are defined as E and RW.

For timing diagrams, figures 3 and 4 (especially the dummy read) is important to READ operations. Figures 34 and 35 shows the timing requirements (hold time, setup time etc.)

For LCD bias, which is related to the LCD technology and I don't know much about that. My personal understanding is that the duty ratio is specify by the LCD manufacturers and related to the voltages V0-V4 and the type of LCD (physical characteristics). Table 17 and "Select LCD bias" command description show the relationships. For the 18pin LCD, it is 1/65 duty and 1/9 bias, so the setting is A3. But I check that I seem mis-coded it as A2 (i.e. 1/7), and has no significant problem. You may try A2 (1/7) and A3 (1/9) and share with us your result.

I guess one thing which may confuse you when reading the codes is that you may have difficulty in matching the the "delay" with the timing diagrams in the datasheet. In fact, many programs just IGNORE the timing requirements and they work! As you may find that the timings (in datasheet) are in ns, for a normal speed 8051 driven by a 11.0592M or (12M) crystal (many people wrote programs based on it), one instruction is already 1us. So many programmers just ignore the detail timings and the program is still OK. Problems only occur when the program is to be used in a high speed uC (for example DS89C450 @12Mhz, one instruction may be down to approx. 33ns). I mentioned the timing requirements simply wants to point out the importance of timing issues, so we can write tidy programs which can be run on various speeds/types of uC, no matter they are PIC, AVR, or MSP....

學到野了......雖然我不是因delay的時序煩惱
we can write tidy programs which can be run on various speeds/types of uC
這正是未跟過project的學生(我)的通病
現在被點醒總好過寫到7788時有問題發生

即是說上邊的字是這樣看?
MI = “H”: 6800 series MPU interface
MI = “L”: 8080 series MPU interface

RW_WR
E_RD

對吧
