Page 3: Introduction
LEDs and demonstrate the close loop of Color Tuning and Daylight features. The kit also serves as a development platform that a customer microcontroller can be used to control AS7225 device as well as onboard LED strings. This user guide describes the features and functions of AS7225 Director Demo Kit. -

The AS7225 Evaluation User Interface software does not need extra installation. Please copy the following files to any folder you would like to work with and run the .exe file to start the GUI. File Comment AS7225_GUI_xx_xx_xx.exe... -
Page 5: Power Supplies
Figure 5. Devices, Connectors and LEDs Power Supplies The AS7225 Director Demo Kit is powered by 12V wall plug power adapter. The 12V supply provides the power to the LDOs as well as MOSFETs and LEDs circuitries. Onboard LDO U1 has 3.3V output, which is used for AS7225, Flash Memory, onboard MCU, and J6 for external sensors. -

LED Circuitries There are six LED strings on AS7225 demo board. Each LED string has three LEDs in serial and it is controlled by a pai of MOSFETs. PWM and FB signals are used by the MCU to control the current through the LEDs. - Page 8 ATCALC <value>OK Starts new calculation Control ATINTTIME <value>OK "Set sensor integration time.

- Page 11 Figure 7. Command Table Note: 1. The internal connection between Host MCU and AS7225 is via I2C communication in AS7225 evaluation demo kit and so the AT Command in Host MCU will work. For accessing the AT Command in AS7225 the Host firmware and hardware communication to AS7225 device should be configured to UART.
