The term **FDI** in electronics most commonly refers to **Future Designs, Inc.**, a company specializing in the design and production of system-on-modules (SOMs), human-machine interface (HMI) solutions, and development tools for embedded systems. Below is an overview of the electronic components and technologies associated with FDI products. --- ### 1. ELI (Easy LCD Interface) FDI’s ELI line consists of plug-and-play intelligent displays designed to interface easily with Single Board Computers (SBCs) like Raspberry Pi or BeagleBone. | Component Type | Description | Key Features | | :--- | :--- | :--- | | **Display Panel** | Industrial-grade LCDs | High brightness, wide viewing angles | | **Touch Controller** | Capacitive or Resistive | USB or I2C interface for touch data | | **Interface Bridge** | HDMI to LVDS/MIPI | Converts standard video signals to display-native protocols | | **Backlight Driver** | Constant current circuitry | PWM dimming support for energy efficiency | ### 2. uEZ GUI (Graphical User Interface) The uEZ GUI series are "Instant GUI" solutions that integrate a microcontroller, memory, and a display onto a single PCB. * **Microcontrollers (MCU):** Typically utilize **NXP LPC** series (ARM Cortex-M4/M7) or **Renesas Synergy** processors. * **Storage:** * **NOR Flash:** For bootloader and firmware storage. * **SDRAM:** For frame buffering and high-speed data manipulation. * **microSD Slot:** For extended media storage (images/icons). * **Connectivity:** Includes RS232, I2C, SPI, and often 10/100 Ethernet PHYs. --- ### 3. SomDIMM (System on Module) FDI produces small form-factor modules that plug into a 200-pin SO-DIMM socket. These act as the "brain" of a larger electronic system. #### Key Electronic Subsystems: 1. **Processor Core:** High-speed ARM processors (e.g., NXP i.MX series). 2. **Power Management IC (PMIC):** Manages multiple voltage rails required by the CPU and DDR memory. 3. **Crystals/Oscillators:** Precise timing components for CPU clocking and RTC (Real Time Clock). 4. **Termination Resistors:** Used for signal integrity on high-speed data lines between the CPU and RAM. --- ### 4. Software Stack (uEZ® Framework) While not a physical "part," the electronic functionality is governed by the **uEZ®** open-source software platform. It provides the drivers for the physical components mentioned above. ```c // Example: Initializing an FDI uEZ GUI display component #include #include void InitializeDisplay() { T_uezDevice lcd; if (UEZLCDOpen("LCD", &lcd) == UEZ_ERROR_NONE) { UEZLCDBacklight(lcd, 255); // Set backlight to full power } } ``` --- ### Summary of Applications * **Medical Devices:** High-reliability touch interfaces. * **Industrial Automation:** Ruggedized control panels. * **IoT Gateways:** Using SomDIMMs for processing and communication.
