KEY_Init ()
Purpose
Configure the keyboard. This API will call the Set_Event() routine to enable an
Interrupt Service Routine (ISR) to handle keyboard scanning.
Synopsis
Void KEY_Init ( IN unsigned char rows_cols, IN unsigned char debounce_scan );
Parameters
RowsCols: Input parameter
Number of rows on keypad (max value is 6) times eight plus number of columns on
keypad (max value is 5), i.e. rows*8 + cols.
Debounce_scan: Input parameter
Number of milliseconds to debounce key (granularity is 4ms) plus number of
milliseconds between key scans (1 to 4 ms) 1 = 1 ms; 2 = 2 ms; 3 = 3 ms and 0=4 ms.
Return Codes
None.
KEY_Wait ()
Purpose
Wait for a keypad input during a maximum time specified by the TimeOut value.
Other events (e.g. Smart Card insertion and removal) can be specified as exit
conditions for this function.
Synopsis
KEY_RC KEY_Wait (
IN Unsigned Int ScanOrder,
IN Unsigned char TimeOut,
IN Unsigned Int ExitOnICCInsert,
IN Unsigned Int ExitOnICCRemoval,
IN Unsigned Word ExitOnEvent,
OUT Unsigned Word *ExitOn,
OUT Unsigned char *KeyCode );
Parameters
ScanOrder: Input parameter
Column scan order, in five sets of three bits each, with the least significant 3-bits (0-
2) indexing the first column scanned and bits (12-14) indexing the fifth column
scanned.
TimeOut: Input parameter
Timeout value in seconds. If no key is entered within this period, the function is aborted.
ExitOnICCInsert: Input parameter
Specifies which, if any, SmartCard insertion events are exit conditions. Bit[n]
corresponds to ICC[n], bit[1] being mapped to the least significant bit. This option
should NOT be used simultaneously with the ExitOnICCRemoval option.
ExitOnICCRemoval: Input parameter
Specifies which, if any, SmartCard removal events are exit conditions. Bit[n]
corresponds to ICC[n]. This option should NOT be used simultaneously with the
ExitOnICCInsert option.
ExitOnEvent : Input parameter
On input, specifies which, if any, other events are exit conditions. Possible values are any
combination of the following:
EVENT_EXT0
0x00000001
EVENT_EXT1
0x00000002
EVENT_EXT2
0x00000004
EVENT_EXT3
0x00000008
EVENT_TIMER0
0x00000010
EVENT_TIMER1
0x00000020
EVENT_ICC
0x00000040
EVENT_RTC
0x00000080
//not available with 73S1205F
EVENT_KEY_DETECT
0x00000100
EVENT_USB
0x00000200
