 ====== User Interface module ======
-(Version 5.3)
 The User Interface module is designed for simple tasks and basic process control. Module has three push-buttons and three LEDs, which can be used as digital inputs and outputs of microcontroller. Additionally to simple LEDs the module is equipped with 7-segment indicator, graphical LCD display, alphanumeric LCD outputs and a buzzer. User Interface module is handy to use along with other modules enabling to control the output device behavior, like motors and display the sensor readings. The module is covered with plexiglass to protect the board from accidents.

 User Interface module is equipped with 7-segment indicator, which is connected to the microcontroller ports through the driver A6275. Driver data bus (S-IN) is connected to pin PC6, clock signal (CLK) to the pin PC7 and latch signal (LATCH) to pin PG2.

 The graphical LCD display on the module is connected to port PA. In parallel the same port has external connector where all pins are aligned according to the standard 2 x 16 alphanumeric LCD 4 bit control. The user can choose whether to use the graphical or alphanumeric LCD. It is not possible to use both at the same time. The graphical LCD's background lighting can be logically controlled by the software. The back-light intensity of the alphanumeric LCD is regulated with on-board resistor and graphical LCD back-light can be controlled by the software. Both LCD displays are connected to port PA but only one at a time can be used. When selecting the alphanumeric LCD the jumper should be removed to avoid random control of graphical LCD background light.

 The buzzer is connected with controller board's pin PG5 and with Vcc. It's possible to generate sound with Robotic Homelab library or with your own software.
