Toggle Switches

When you use the Gravio matrix led, you can control whether the matrix uses gravity sensing to rotate the picture by flipping the switch. When the flipping switch is on the right, the gravity sensing is turned on. At this time, when you rotate the Gravio matrix led, the picture will be Follow the rotation, always facing up; when the toggle switch is on the left, the gravity sensor is turned off, no matter how you rotate the Gravio matrix led, the picture will not rotate

screen Switches

screen the switch can control the screen switch.

Pair button

When you need to wirelessly transmit pictures to Gravio matrix led, you need to add it to the Zigbee gateway network now. When the gateway is allowed to access the network, press and hold the pair button for 5 seconds, and the Zigbee icon on the screen will flash. At this time, it will be added to the network of your gateway soon. After joining the network, the flashing Zigbee picture will be displayed. Prohibited, at this time you can transfer pictures or animations through the host computer

Network access steps: (for example we use Gravio Receiver2)
Insert Gravio receiver into pc, Mac, or Linux, open serial debugging tools, such as sscom

Typed hex:00 00 03 00 00 AA (build a network)
Go on:00 00 10 00 01 FF AA (Allow devices to connect to the network)
At this time, press and hold the button of Gravio matrix led for 5 seconds until the Zigbee icon will flash

When a gateway receives network access information,
