Zolertia Orion Router button configuration
Buttons on the eth-gw are connected as follows: BUTTON_USER -> PA3, S1 user button, shared with bootloader BUTTON_RESET -> RESET_N line
#define	BUTTON_USER_PORT GPIO_A_NUM
	BUTTON_USER -> PA3.

ADC configuration
These values configure which CC2538 pins and ADC channels to use for the ADC inputs. There pins are suggested as they can be changed, but note that only pins from PA can be configured as ADC. The Zolertia eth-gw, as it is, only allows 3.3VDC sensors. The internal ADC reference is 1190mV, use either a voltage divider as input, or a different voltage reference, like AVDD5 or other externally (AIN7 or AIN6). The ADC1 is exposed over the JP9 connector
#define	ADC_SENSORS_PORT GPIO_A_NUM
	ADC GPIO control port.

Detailed Description

The Zolertia Orion Router includes an Ethernet ENC28J60 controller with active POE (power over ethernet), operating over IPv4/IP64. It features a dual RF interface (2.4GHz and 863-950MHz) with external antenna connectors, a power on/off switch and programable user button.
