10.4 Poll Key Press

Syntax

Hexadecimal 0xFE 0x26

Decimal 254 38

ASCII 254 “&”

Description This command returns any buffered key presses via the serial interface.

The host system must be set up to receive key codes. When the display

receives this command, it will immediately return any buffered key

presses which may have not been read already. If there is more

than one

key press buffered, then the high order bit (MSB) of the returned key

code will be set (1). If this is the only buffered key press, then the MSB

will be cleared (0). If there are no buffered key presses, then the

returned code will be 0x00. Please note that to make use of this

command, the “Auto Transmit Key Presses” mode should be off.

NOTE

This command is not available in I2C. To read keys in I2C mode, one just needs

to address the module and read a byte. No preceding commands are necessary. If there are

no keys pressed the read will result in a 0x00.

Remembered No

10.5 Clear Key Buffer

Syntax

Hexadecimal 0xFE 0x45

Decimal 254 69

ASCII 254 “E”

Description This command clears any unread key presses. In a

menu application, if

the user presses a key which changes the menu context, any following

key presses may be inaccurate and can be cleared out of the buffer

between menu changes to prevent jumping around the menu tree. It may

also be used, in effect, to reset the keypad in case the host application

resets for whatever reason.

Remembered No

10.6 Set Debounce Time

Syntax

Hexadecimal 0xFE 0x55 [time]

Decimal 254 85 [time]

ASCII 254 “U” [time]
