This example shows how to control plant watering device. The example is applicable for all connection types supported by the GUI-O application (i.e., Bluetooth, Bluetooth LE, IoT and Usb).

The final result is shown below. During the example, you can always consult the GUI-O developer manual for more information.

First, the following images must be copied onto your Android device under /Android/data/com.guio.guioapp/files/Pictures

NoConnB.jpg
Soil1.jpg
waterx.gif
ZCloudy.jpg
ZSunny_Cloudy.jpg

ZRainy.jpg
ZNight_Rainy.jpg
ZNight.jpg

Alternatively, the images can be loaded during run-time within the GUI-O application by specifying the corresponding url path in the parameter list (see comments in the code example below).

NOTE: Since Android 11, the /Android/data/com.guio.guioapp/files/Pictures path is no longer accessible directly from the device due to Google's security restrictions. You can, however, access the path by connecting the Android device to a PC and transfer the images.

The GUI initialization procedure is shown in the following code block:

Note that the images can also be loaded at run-time (within the GUI-O application) from the specified url. For example:

|IM UID:im1 X:50 Y:15 W:100 H:100 ROT:0 SHE:0 IP:"https://i.imgur.com/3Bk5WxR.jpg"

This invokes the GUI-O application downloader and displays the image after successful transfer. Downloaded images are saved locally. All subsequent initialization requests trigger loading such images from the local resource, even if the image path is specified as an url.

Drawing chart data, reacting to user input and updating widgets is thoroughly described in the GUI-O developer manual in the "Widgets API" section.

This example shows how to control and monitor temperature of your central heating system. The example is applicable for all connection types supported by the GUI-O application (i.e., Bluetooth, Bluetooth LE, IoT and Usb).

The final result is shown below. During the example, you can always consult the GUI-O developer manual for more information.

First, the following image must be copied onto your Android device under /Android/data/com.guio.guioapp/files/Pictures

Alternatively, the image can be loaded during run-time within the GUI-O application by specifying the corresponding url path in the parameter list (see the code example below).

NOTE: Since Android 11, the /Android/data/com.guio.guioapp/files/Pictures path is no longer accessible directly from the device due to Google's security restrictions. You can, however, access the path by connecting the Android device to a PC and transfer the image.

The following commands show how to draw temperature and humidity values to the chart (point-by-point):

@temp_chart PLI:"pl1" PLC:"#cd1e2c" YP:"27.0"
@hum_chart PLI:"pl1" PLC:"#80c5de" YP:"32.0"

Since both charts are confgured to display time on X-axis, the points are added automatically (based on the current time). This means that XP parameter need not be specified. It is also possible to draw multiple plots to the same chart.

Advanced chart data drawing, reacting to user input and updating widgets is thoroughly described in the GUI-O developer manual in the "Widgets API" section.
