INTENDED USE

Description
The all-in-one Lighting Development Kit provides an easy solution to mix RGBW color for different lighting situations, amplify the growth of plants with the horticulture panel or even for indoor illumination based on Human Centric Lighting (HCL). The MagI³C Multi Color LED driver can power all three Panels. With four MagI³C LED Step Down High Current Modules (172946001) as its heart it is possible to control the intensity and color of each of the four LED strings individually to meet the applications needs.
The controlling is done via an app for both iOS and Android, which is developed to control the reference design using Bluetooth® LE. The board can be used for horticulture, mixing of different white color temperatures, mixing of RGBW LED combinations (red, green, blue, white) or just to change the intensity of one type of LED.
The board includes an EMI filter in order to comply with the limits of the EN55015 conducted lighting standard and the CISPR32 standard for radiated EMI (tested with 1m output cable length) even while dimming the LED strings.

ASSEMBLY

WEILLUMINATE APP DESCRIPTION

Overview
The WEilluminate app can be used to control the MagI³C Multi Color LED Driver reference design via radio. It uses the Bluetooth® LE connection of the mobile device to establish a connection to the Proteus-I (2608011024001) Bluetooth® LE module on the reference design board. Once connected, changes of the LED channel brightness and color distribution can be performed using the sliders in the app.

The WEilluminate app is an evaluation tool that is intended for development purposes only. It is recommended to check regularly for available updates. It does not underly the PCN notification process of Würth Elektronik eiSos.

System Requirements
This app is intended to run on an Apple or Android mobile devices, smartphones or tablets, with integrated Bluetooth® LE capabilities. Please make sure your device has installed the most recent iOS and Android updates, security patches and the most recent app version. This app is optimized for portrait mode and was tested with iPad mini 2 and iPhone XS, each with iOS v12.4.1 and iOS 13.3.1. In order to use the app the user is required to grant the corresponding requested rights, e.g. to use the Bluetooth® LE interface of the smart device.

Compatible Bluetooth® LE Devices
The WEilluminate app supports connection to the Würth Elektronik eiSos Proteus module implemented in the reference design.

Internet Connection
The WEilluminate app works offline and requires no internet connection to be used. However, the links provided in the info tab require an internet connection to be opened by the system internet browser.

Installation
The WEilluminate app can be found in both the official App Store or in the Play Store. Moreover, the app can be also found on our website.

Operation
This chapter provides operational instructions for the WEilluminate app .

1. Starting the Program
   After successful installation, click the WEilluminate app icon on the home screen of your mobile device to start the application.

2. Splash Screen
   During the application startup phase your mobile device shows the following splash screen and then proceeds to the scan tab of the app.

3. Scan Tab
   This tab lists all Bluetooth® LE devices supported by this app within range. Currently, only Würth Elektronik eiSos Bluetooth® LE modules of the Proteus family are supported by the app. In ad-dition, a demo device is always the topmost entry in the found devices list. This device enables the user to try the app even in case no suiting Bluetooth® LE device is available in radio range.

   • The list will show the device names of the detected Bluetooth® LE devices, which are specified in the devices itself and only interpreted by the app. The names can not be changed from the app. For the Proteus modules the short device name in the list defaults to either A2621 for Proteus-I or A2623 for Proteus-II.
   • The user can select a device from the list and initiate the connection process by clicking on it. The Bluetooth® LE connection will be established automatically. The security option of the Proteus module is set to open, which means no pin code has to be entered and anyone can connect to it. If another security option is set the app prompts to enter a pin code to establish the Bluetooth® LE connection. It is not possible to change the security option from within the app. After a successful connection establishment the app switches automatically to the channels tab.
   • Then swiping back to the scan tab, the connected device is indicated with a red check icon as shown in the following screenshot. A gray check icon shows the last connected device but the gray indicates that the connection is not active.

4. Channels Tab
   The channel tab allows to control the LED brightness of the reference design. Each of the four channels can be controlled individually and the additional brightness slider works as a global multi-plier for all four channels. The % values shown for each channel are the percentages with brightness already calculated in and rounded down. Whereas the brightness % value represents its slider value.
   If the brightness slider is set to 0 % none of the channels will be active. This means for example a value of 50 % for the channel 1 on the reference design can be created by a multitude of slider positions of channel 1 slider value and brightness slider value.
   For example:

   • Brightness slider 100 % and channel 1 slider 50 %resulting in channel 1 overall value 50 %
   • Brightness slider 50 % and channel 1 slider 100 %resulting in channel 1 overall value 50 %
   • Brightness slider 71 % and channel 1 slider 71 % resulting in channel 1 overall value 50 %
   • This means whenever the brightness slider is set to 0 % any LED channel will be disabled independent of their slider’s value. The app is restricted to a certain number of radio frames per second (in BLE terms: connection interval) which means that not every step of a (fast) change will be transmitted on the radio. The value for the responsiveness is chosen so a good user experience is created but can be easily modified.
     If the brightness slider is set to 0 % none of the channels will be active.

5. Info Tab
   Users can swipe left or touch the info tab symbol at the bottom to switch view to the info tab. This tab gives general app version information and allows accessing the privacy policy, contact information and imprint by forwarding a link to the system’s default web browser.
