4.3.6.1 Keypad Inputs
The RabbitFLEX Configurator will automatically assign pins from connector J5 as the keypad inputs and
outputs. Keypad inputs and outputs are digital I/O circuits. Keypad inputs are read by the API function
flexKeyProcess(). This function must be called frequently in a software application in order to poll
the keypad for key presses. See sample program Samples/RabbitFLEX_BL300F/keypad.c for
an example of how to use the keypad API functions. (The “RabbitFLEX_BL300F” folder was formerly
named “RabbitFLEX_SBC40.”)
