8.1User Interface

The CC2511 Dongle has one button and one LED that can be used to interact with the user. The LED is connected to pin P1_1. Setting P1_1 high (to logic 1) will turn the led on.

The button is connected to pin P1_2 and GND. The pin P1_2 should be configured as an input with pull-up. The button is pushed when P1_2 is pulled low (to logic 0).

8.2USB interface

The CC2511 Dongle has a standard USB connector. The dongle is powered through this connector. On the D+ line there is a pull-up used to identify the dongle as a full-speed USB unit on the USB bus. The pull-up can be controlled from the firmware, using P1_0. This enables the firmware to be connected to the USB bus for a period of time before it signals its presence to the USB hub.
