![]() The plugin generates a ScanCode, depending on either the button-order in ‘direct’ mode, or the row/column position in the ‘matrix’ mode. At every crossing of the matrix, a key can be connected, connecting the row and column wires when pressed. Matrix chip mode means that a matrix is created with half of the I/O ports as row and the other half as columns. The PCA8575 chip doesn’t have internal pull-up resistors, so these must be added externally.ĭirect chip mode means that each I/O port is connected to a key, and connects to GND when pressed. ![]() Depending on the configuration, this allows to connect up to 72 keys to a single I/O chip (9*8 matrix). Currently supported chips are PCA8574/PCA8574A (8 I/O ports), MCP23017 and PCA8575 (16 I/O ports). The keys are connected directly or in a matrix to an 8 or 16 port I2C I/O chip. This plugin is used to get input from buttons/keys or a keypad transformed to a ScanCode, that can be handled in rules.

You can modify EditText as per your requirement. Take 4 EditText in and set maxLength attribute to 1 in xml for all 4 EditTexts. I have did something like this in Fragments. Pardon me if I'm wrong and any suggestion regarding coding or the way of writing code in stackoverflow is highly appreciated. This is the first time i have dared to answer this question. I have learnt lot of things from stackoverflow. When I stuck in coding I always use to refer stackoverflow.
