USB interface
®
The CC2400EB connects to a PC via a USB interface. SmartRF
Studio uses the USB
interface to control the CC2400EB. The USB interface can be used both to configure the
CC2420 and transfer data. Chipcon provides a Windows driver that is installed as part of the
®
®
SmartRF
Studio installation process. This driver must be present for SmartRF
Studio to
communicate with the CC2400EB.
Because USB is used, the CC2420DK will only function with PCs running Windows 98,
Windows ME, Windows 2000, Windows XP or newer. Windows NT and Windows 95 cannot
be used since they do not support USB.
RS-232 interface
A serial port is included on the CC2400EB. This is intended for debugging purposes, and
®
cannot be used to connect the Evaluation Board to SmartRF
Studio.
Jumpers
The jumpers are used to configure the Evaluation Board. The factory default settings are
shown below. This is the jumper setting when the CC2400EB voltage regulator is used to
power the CC2420.
