The LTC®3207/LTC3207-1 is a 600mA LED/Camera driverwhich illuminates 12 Universal LEDS (ULEDS) and onecamera fl ash LED. The ULEDS are considered universalbecause they may be individually turned on or off, setin general purpose output (GPO) mode, set to blink at aselected on-time and period, or gradate on and off at aselected gradation rate. This device also has an externalenable (ENU) pin that may be used to blink, gradate, orturn on/off the LEDS without using the I2C bus. This may beuseful if the microprocessor is in sleep or standby mode. Ifused properly, these features may save valuable memoryspace, programming time, and reduce the I2C traffi c.
Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDS.

The aim of this application note is to show to scan the 4x4 matrix keypad
multiplexed with a four 7-segment display. The software attached to this application
note scans the pressed key and displays it on the multiplexed 7- segment LEDS.
This application note makes obvious Interrupt capability of the STR710 device
to offer a better key scan .
his design is the initial design when the board is powered-up. It increments a counter and displays the value on the
7-segment displays and LEDS. An image is also displayed on the VGA port.
Spartan 3 Digilent Demo:This demo drives the perphrials on the Spartan 3 board. This drives a simple pattern to the VGA port, connects the switches to the LEDS, buttons to each anode of the seven segment decoder. The seven segment decoder has a simple counter running on it, and when SW0 is in the up position the seven segment decoder will display scan codes from the PS2 port. This demo how ever does not drive the RS-232 port or the memory. This is a simple design done entirely VHDL not microblaze.
VDSP++打開。This directory contains an example ADSP-BF537 RTC project that does a basic blink routine and
then puts the part in deep sleep mode to be woken up from a RTC Stopwatch Event. Once woken up,
the RTC is reconfigured to toggle the EZ KIT LEDS using RTC second, minute, hour, and day interrupts.
