Silicon Labs Explorer Kit XG24-EK2703A User Buttons and LEDs Design Tips
The figure above shows the user interaction components on the EFR32xG24 Explorer Kit — two user buttons and two status indicator LEDs — which are used for human-machine interface and status feedback. Both are connected to the core chip EFR32MG24 via GPIO pins and support software programming control.
Design Tips
- Button Debouncing: Although hardware RC filtering is provided, it is recommended to add software debouncing logic (such as delay detection) in software programming to avoid false triggers.
- LED Driving: LED0 uses an active-high design. It can be turned on directly by outputting a high level, and no additional driver circuit is required.
- Pin Multiplexing: Pins PB02 and PA04 can be reused as general-purpose GPIOs, but the pin functions must be correctly configured in the code (to avoid conflicts with default functions).
