Specifications

 

1. module: 20.5mmx41mm

 

2. the module weight: 57g

 

Introduction to 1602-character LCD

 

1602LCD main technical parameters:

 

1. display capacity: 16x2 characters

 

2. chip working voltage: 4.5-5.5V

 

3. current: 2.0mA (5.0V)

 

4. module optimum working voltage: 5.0V

 

5. character size: 2.95x4.35 (WxH) mm

 

 

1 VSS GND 9 D2

 

2 VDD supply cathode 10 D3

 

3 LCD display bias 11 VL D4 data

 

Select 12 D5 4 RS data/command data

 

Select 13 D6 5 r/w for read/write data

 

6 enable signal e 14 D7

 

7 D0 data 15 BLA backlight cathode

 

8 D1 16 BLK Blu anode

 

1th feet: VSS for the power supply.

 

2nd leg: VDD 5V power supply.

 

3rd leg: VL LCD contrast adjustment end, followed by a positive contrast when the power of the 

weakest, grounding the contrast

 

The highest contrast ratio too high will have a "ghosting", used by a 10K when the potentiometer to 

adjust the contrast.

 

4th leg: RS to register choices, high level selection data, low level select instruction registers.

 

The 5th foot: r/w for read/write signal lines, high level for read operations, write low level. Dang RS

 

And R/W work together to lower level instruction or the address could be written, when RS is higher 

for low level R/W level

 

Busy signal can be read, as RS for high level R/W for low level data can be written.

 

6th leg: e end-for-end, when e duanyou-level jumps to a low level, LCD module executes the command.

 

Di7~14 feet: D0~D7 for 8-bit bidirectional data line.

 

The 15th foot: cathode backlight.

 

The 16th foot: negative backlight.

 

 

1602LCD command Description:

 

1602 LCD controller within the total 11 control orders, as shown in the table the following table:

 

Ordinal number instruction RS R/W D7 D6 D5 D4 D3 D2 D1 D0

 

1 Qing ping 0 0 0 0 0 0 0 0 0 1

 

2 the cursor returns 0 0 0 0 0 0 0 0 1 *

 

3 reset input mode 0 0 0 0 0 0 0 1 I/D s

 

Display on/off control 4 0 0 0 0 0 0 1 d c b

 

5 character or cursor shifted 0 0 0 0 0 1 S/C R/L * *

 

6 reset the function f * 0 0 0 0 1 DL n *

 

Character memory address 0 0 0 1 7 reset character memory address

 

8 reset the data memory address 0 0 1 displays the data memory address

 

9 0 1 BF counter read busy flag or address address

 

Write count to 10 or DDRAM CGRAM) 1 0 to write the contents of the data

 

11 CGRAM or DDRAM reading 1 1 read out the contents of the data

 

1602 LCD module, reading and writing, screen and cursor operations are achieved through the directive programming. (Note: 1 high, 0 is low level)

 

Instructions 1: clear display, order code 01H, reset the cursor position to the address 00H.

 

Instruction 2: reset the cursor, the cursor returns to the address 00H.

 

Order 3: cursor, and display mode settings I/D: cursor moving direction, move high to the right, low level s to the left:

 

Move all text is left or right on the screen. High level represents effective, low level is not valid.

 

Instruction 4: display switch control. D: control of display on and off, high level open display, low power

 

Flat locked display c: controls the cursor on and off, high level indicates that a cursor, low level indicates no cursor b: control

 

Whether the cursor is flashing, flashing high level, low level does not Flash.

 

Directive 5: cursor or display SHIFT S/C: text to display high level moves, low level mobile cursor.

 

Instruction 6: feature command DL: high level is a 4-bit bus, low level as an 8-bit bus n: low

 

Usually consist of a single display, high voltage dual line display f: low level display dot matrix characters 5x7, high voltage display

 

5x10 dot matrix characters.

 

Directive 7: character generator RAM address settings.

 

Directive 8:DDRAM address settings.

 

Directive 9: reading of busy signals and the cursor address BF: for free sign-bit, line busy module can't get

 

Receive commands or data, if low level is not busy.

 

Directive 10: write data.

 

Directive 11: reading the data.

 

HD44780 compatible chip timeline is as follows:

 

Read I RS=L,R/W=H,E=H o D0-D7= status word

 

Write commands RS=L,R/W=L,D0-D7= script, e = high output pulse is not

 

Reading data input RS=H,R/W=H,E=H output D0-D7= data

 

Write data entry RS=H,R/W=L,D0-D7= data E= high output pulse is not

 

1602LCD initialize (reset):

 

Delay 15mS

 

Writing instruction 38H (busy signal will not be detected)

 

Latency 5mS

 

Writing instruction 38H (busy signal will not be detected)

 

Latency 5mS

 

Writing instruction 38H (busy signal will not be detected)

 

Each subsequent write command, the read/write data operations are required to detect busy signal

 

Written instructions 38H: display mode settings

 

Written instructions 08H: display off

 

Written instructions 01H: displays a clear screen

 

Written instructions 06H: displays the cursor settings

 

Writing instruction 0CH: displaying open and cursor settings
