2 SOFTWARE CONTROL J default setting is closed (short). If it is set to open, the MCU's SDB, SCL, SDA and CLK pin will be high impedance (open-drain) and external control is allowed. SDB SCL SDA 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/a vr/. Then download the latest ISFL test firmware (sketch) from the ISSI website shtml. ) Open JP. ) Connect the pins from Arduino board to ISFL EVB: a) Arduino V pin to ISFL EVB. b) Arduino to ISFL EVB. c) Arduino SDA (A) to ISFL EVB SDA. d) Arduino SCL (A) to ISFL EVB SCL. e) If Arduino use.v MCU, connect.v to ISFL EVB SDB, if Arduino use.v MCU, connect.v to EVB SDB. (Arduino UNO is.v, so SDB=.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 ISFL.
