6-CHANNEL LIGHT EFFECT LED DRIVER

Transcription

1 -CHANNEL LIGHT EFFECT LED DRIVER DESCRIPTION ISFLA is a -channel light effect LED driver which features two-dimensional auto breathing mode and an audio modulated display mode. It has One Shot Programming Mode and PWM Control Mode for RGB lighting effects. The maximum output current can be adjusted in levels (ma~ma). FEATURES Supply voltage range from.v to.v Two groups RGB, single color LED breathing system-free pre-established pattern independently controlled automatic and semiautomatic breathing system-free pre-established pattern independently controlled outputs of PWM steps levels programmable output current Audio mode with AGC function Cascade for the synchronization of chips QFN- (mm mm) package QUICK START RECOMMENDED EQUIPMENT.V, A power supply ABSOLUTE MAXIMUM RATINGS.V power supply Caution: Do not exceed the conditions listed above, otherwise the board will be damaged. PROCEDURE The ISFLA evaluation board is fully assembled and tested. Follow the steps listed below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. ) Short JP to connect by board MCU (default short). ) Connect the VDC power to the connector (TP&TP) (Skip this step if use Micro-USB as power input). ) Turn on the power supply/plug in the Micro USB Pay attentio to the supply current. If the current exceeds A, please check for circuit fault. EVALUATION BOARD OPERATION The ISFLA evaluation board has five display modes. Press K to switch configurations. ) lamps breathe at the same time ) The RGB monochromatic breathes ) RGB audio mode ) lamps breathe one by one ) lamps audio mode Note: ISFLA solely controls the FxLED function on the evaluation board.

2 -CHANNEL LIGHT EFFECT LED DRIVER SOFTWARE CONTROL J default setting is closed (short). If it is set to open, the MCU's, SCL, and CLK pin will be high impedance (open-drain) and external control is allowed. SCL Figure : Photo of Arduino UNO connected to Evaluation Board The steps listed below are an example using the Arduino for external control. The Arduino hardware consists of an Atmel microcontroller with a bootloader allowing quick firmware updates. First download the latest Arduino Integrated Development Environment IDE (.. or greater) from Also download the Wire.h library from and verify that pgmspace.h is in the directory program Files(x)/Arduino/hardware/tools/avr/avr/include/avr /. Then download the latest ISFLA test firmware (sketch) from the ISSI website tml. ) Open JP. ) Connect the pins from Arduino board to ISFLA EVB: a) Arduino V pin to ISFLA EVB. b) Arduino to ISFLA EVB. c) Arduino (A) to ISFLA EVB. d) Arduino SCL (A) to ISFLA EVB SCL. e) If Arduino use.v MCU, connect.v to ISFLA EVB, if Arduino use.v MCU, connect.v to EVB. (Arduino UNO is.v, so =.V) ) Use the test code in appendix I or download the test firmware (sketch) from the ISSI website, a.txt file and copy the code to Arduino IDE, compile and upload to Arduino. ) Run the Arduino code and the initial mode will change the RGB LED brightness every second. Note: the white color LEDs cannot be controlled when the onboard STMFCT is disabled. (Some early board we provided is still controlling the white color LED, if want to switch between single color LED and RGB, remove the U and connect the to the LED+) Please refer to the datasheet to get more information about ISFLA.
