What it does

Sweep the 2.4 GHz band using the NRF24 hardware and display a spectrum-style view (many narrow channels—README cites 128 channels). Useful for seeing congestion beyond Wi-Fi alone (Zigbee-like devices, remotes, etc.).

How to use

1. Ensure NRF24 module(s) are seated and antennas attached.
2. Open 2.4GHz → Scanner.
3. Let the sweep run; read the graph against any on-screen legend.
4. Exit via submenu / status controls.

Hardware

CE/CSN pins are defined in shared.h (CE_PIN_*, CSN_PIN_*) for up to three NRF24 instances on some shields.
