  • Figure:1 Capacitive Touchscreen Display Reference Design

    Capacitive Touchscreen Display Reference Design

    Posted Feb 23, 2015 By Design Library
    Capacitive touchscreen displays generally provide a higher quality and better user experience than traditional resistive touchscreen displays. This reference design shows how to interface a capacitive touchscreen display to the Sitara AM437x processors. The display has an integrated touchscreen controller that interfaces with the AM437x via its I2C port.

    Synchronous Buck Converter Optimized for Small Size and Low Output Voltage

    Posted Feb 16, 2015 By Design Library
    PMP9194 uses the TPS54020 synchronous-buck SWIFT converter with integrated FETs to provide a 10 A/1 V solution in less than 22 mm x 12 mm of total board space area. This reference design uses a small 1.1 µH inductor, 2×100 µF ceramic output capacitors, and small 0402 external components to save space. The device switches at 300 kHz and acheives 87% peak efficiency from a 12 V input to a 1 V…
  • Figure:3 Power Solution for C667x DSP AVS Core (CVDD) with Dynamic Voltage Scaling

    Power Solution for C667x DSP AVS Core (CVDD) with Dynamic Voltage Scaling

    Posted Feb 09, 2015 By Design Library
    This reference design aims to supply the AVS core supply (CVDD) in the Keystone Multicore DSPs, mainly the C66x series. The C66x series uses SmartReflex technology to enable the DSP to control its supply voltage. In order to meet this requirement, this design combines a Synchronous Buck Converter (TPS56121) with the voltage Programmer for POL (LM10011). The LM10011 accepts a 6-bit or 4-bit VCNTL…

    Embedded USB 2.0 Reference Design

    Posted Feb 02, 2015 By Design Library
    The USB 2.0 reference design guidelines are extremely important for designers who want to ensure that their design will pass USB2.0 electrical compliance testing. The guidelines are applicable to AM335x and AM437x but also generic to other processors. The approach taken for these guidelines is highly practical, without complex formulas or theory.
  • Figure:5 Xilinx Artix 7 FPGA Power Management Reference Design

    Xilinx Artix 7 FPGA Power Management Reference Design

    Posted Jan 27, 2015 By Design Library
    The Artix 7 power management reference design board uses power modules, linear regulators, and a PMBus compliant system controller to supply all required core and auxiliary voltages needed by the FPGA, including DDR memory termination. A Digital Power graphical user interface is used to monitor the voltage and current levels of the board’s power rails.

    Auto Intensity Control of Street Lights using Microcontroller

    Posted Jan 25, 2015 By Sudheer Gupta
    Here, we have explained about the circuit that automatically controls the intensity of street lights which is designed using microcontroller and LEDs. It is very useful to save the power.
  • Figure:7 Single-Phase Energy Meter Solution for Advanced Applications

    Single-Phase Energy Meter Solution for Advanced Applications

    Posted Jan 19, 2015 By Design Library
    This design features a dual-core microcontroller implementing an integrated electricity metering solution. The meter has been tested to prove 0.5% accuracy across a current dynamic range of 2000:1 by using a precision, low-noise op-amp and a programmable gain amplifier (PGA) to provide four gain stages. The metrology calculations are performed independently of the MCUs’ integrated cores, leaving…
  • Figure:8 Old display

    Lexicon PCM80 Replacement Display

    Posted Jan 18, 2015 By Velimir Knezovic
    Old Vacuum fluorescent displays can be very hard to find, to make things worse lexicon used special ones (made by company named Futaba) with interface not compatible with HD44780. To be more precise, exact display model number is M202SD01HA, and it’s used on PCM 80 and PCM 90.
