4 Guided Tour of the GUI/EVK
4.1 Introduction
The paragraphs in this chapter allow the user to get to know the basics of the EVK and the SX863x/4x and to get
the user acquainted with the GUI and the EVK and the way to use them.
The more technical details and functioning are described in following chapters and in the product datasheets
(references [1] to [13]).
The steps in this chapter are straight forward and do not require a very detailed knowledge of the SX863x/4x neither
of the EVK.
4.2 Active/Doze/Sleep Mode/Wake-up
Directly after a power up of the EVK the SX863x/4x will enter Active mode and sensor pins will be sensed every
30ms.
The user can change the operation mode by clicking on the icons.
The actual operation mode is then highlighted as shown below.
active mode
doze mode
sleep mode
Figure 13: Operating Modes
The sensor pins are sensed every 195 ms in Doze Mode.
There are 2 ways from Doze mode to Active mode.
1) Use the Operating mode icon Active
2) Touching the button BT0 for at least 195ms. After the release of BT0 the Active mode is entered automatically.
This is the so-called automatic wakeup. In case other buttons are touched nothing happens and Doze mode is
maintained.
4.3 LED fading on GPO pins
Touching BT0 will enable LED D0 on the EVK.
When BT0 is released the LED will remain on for some time and then go OFF slowly.
It is easy to change the LED behavior by the following steps.
- select the GPIO tab
