This is a demonstration program which draws a keypad on the LCD and uses the touch screen to allow an operator to key-in an access code. Two possible codes are allowed to grant to different levels of access. Additionally the push button is used to allow an operator to send Moorse Code pulses in to the device which is checked against two characters to determine if there was a match, and if so, access is granted.
Dependencies: LCD_DISCO_F429ZI mbed TS_DISCO_F429ZI mbed-os BSP_DISCO_F429ZI
Also draws a mushroom on the screen and animates it.
