Peripherals
5. Peripherals
The starter kit has a set of peripherals that showcase some of the features of the EFM8 EFM8SB2 Sleepy Bee microcontroller.
Be aware that most EFM8 I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when
using the breakout pads for your application.
5.1 Push Buttons and LEDs
The kit has two user push buttons. They are connected to the EFM8, and are debounced by RC filters with a time constant of 1 ms. The
buttons are connected to pins P0.2 and P0.3.
In addition to the two push buttons, the kit also features a tri-color LED that is controlled by EFM8 GPIO. The LED is connected to pins
P2.0, P2.1, and P2.2 in an active-low configuration.
