When a new VI or existing VI is opened, the front panel appears, which is a user interactive interface. The front panel is shown in Figure 1.5. It includes indicators, graphs, push buttons and knobs. Indicators are used as output devices and to display data that the block diagram receives or generates. Controls are used as inputs to send data and simulate input devices in the block diagram. The front panel emulates the control panel of conventional instruments and also produces test panels or represents operation and control of processes.

In the front panel, there are two fundamental components: the indicators and controllers. Thus, the frontal panel can be the front panel of a physical instrumentation device. On the other hand, the block diagram has all the blocks and nodes to build a LabVIEW program. The block diagram menu and frontal panel menu are illustrated in Figure 2.18.

At the heart of the UI is an Atmel ATMEGA328 microcontroller. This device formulates the commands to the VSM and decodes the responses, as well as responding to inputs from the operator via the user interface. The microcontroller operates at 5 V and 16 MHz, is powered by a supply derived from a USB socket on the urodynamics equipment and is programmed in the Arduino language. Connection to the 20 × 4 character LCD is made by a PCB mounted RJ45 socket. Connection to the front panel controls is made by solder pads on the PCB. A cable mounted plug and socket arrangement allows for disconnection of the front panel to ease assembly, dismantling and servicing. The microcontroller is programmed initially through an in circuit serial programmer (ICSP) header located near the device. This allows the installation of a boot loader that supports programming and communications through the on board universal asynchronous receiver transmitter (UART). This is done via the USB interface using an FT232RL USB to serial UART, allowing convenient code uploading and modification, ease of viewing debug messages and manual communication with the VSM.

LabVIEW programing is based on the front panel and block diagram windows, which use virtual instruments imitating physical instruments. These subsystems are the most basic and important components of the LabVIEW framework. The block diagram, consisting of input, output, functions, and wires, is a graphical source code that controls individual operations. Basic structures connect multiple functional nodes, which are linked by wires. The front panel is a graphical user interface showing both controls and indicators connected in each block diagram.[20] It combines all of the block diagrams and determines the operational order. Using the front panel, variables are controlled or set as inputs, and the results are displayed simultaneously.
