Keypad (Generic) component

Generic component to create a raster scanned custom keypad or button matrix. By default, each key is labelled with its ASCII return character. Alternatively, each key may use an image as a label. To use a custom key shape, build a single key, then point to it with the 'Custom key shape" property. If the custom shape is a group, any item within the group that has a handle beginning with "label" will have the key label/image applied to it automatically.

Examples

3 x 4 Keypad Schematic

Example schematic of a 3 x 4 Keypad.


Multi Digit Number Entry

A simple example to take in a decimal number (0-65535) from the user and then use this number as a delay for flashing a LED on and off. Shows the principals of reading the keypad and building up a multi-digit number.

Keypad Delay


Keypad Based Door Entry System

Each key press on the keypad is fed into the Circular Buffer component. We then poll the buffer to see if the correct characters for the password have been entered.

Keypad Door Entry

If the correct sequence is detected then we activate the solenoid component for 5 seconds.






Macro reference

GetAscii

GetAscii
Gets the ASCII value for the current keypress. If no key is pressed then the macro returns the value 255. 
- BYTE Return


GetIndex

GetIndex
Gets the index value for the current keypress. If no key pressed then the macro returns the value 255. 
- BYTE Return


GetNumber

GetNumber
Gets the numeric value for the current keypress. If no key pressed then the macro returns the value 255. 
- BYTE Return


GetString

GetString
Gets the ASCII value for the current keypress and returns in the form of a string. If no key pressed then the macro returns a null string. 
- STRING Return


WaitPressed

Properties
Dimensions
Keys
Number of columns (left to right) in the array of keys. Must be a value from one to four. 
Return Values
ASCII
A list of return values for the 'GetString' and 'GetASCII' macros. Enter a string with one character per key, in order of key scanning. Columns are counted first (left-to-right), then rows (direction set by the 'First Row' property) e.g. for a 2*2 grid, the order would be... [Row0, Column0], [Row0,Column1], ][Row1, Column0], [Row1, Column1] 
Numbers
A list of return values for the 'GetNumber' macro. Enter a comma separated list with one integer value per key, in order of key scanning. Columns are counted first (left-to-right), then rows (direction set by the 'First Row' property) e.g. for a 2*2 grid, the order would be... [Row0, Column0], [Row0,Column1], ][Row1, Column0], [Row1, Column1]
