Digital Pot Control
This example controls an Analog Devices AD5206 digital potentiometer.
The AD5206 has 6 potentiometer channels. Each channel's pins are labeled
A - connect this to voltage
W - this is the pot's wiper, which changes when you set it
B - connect this to ground.
The AD5206 is SPI-compatible,and to command it, you send two bytes,
one with the channel number (0 - 5) and one with the resistance value for the
channel (0 - 255).
The circuit:
* All A pins of AD5206 connected to +5V
* All B pins of AD5206 connected to ground
* An LED and a 220-ohm resisor in series connected from each W pin to ground
* CS - to digital pin 8 (SS pin) P2.0
* SDI - to digital pin 14/15 (MOSI pin USI/USCI) P1.6/P1.7
* CLK - to digital pin 7 (SCK pin) P1.5

// include the SPI library:
#include <SPI.h>
// set pin 8 as the slave select for the digital pot:
const int slaveSelectPin = PB_5;
void setup() {
// set the slaveSelectPin as an output:
pinMode (slaveSelectPin, OUTPUT);
// initialize SPI:
SPI.begin();
}
void loop() {
// go through the six channels of the digital pot:
for (int channel = 0; channel < 6; channel++) {
// change the resistance on this channel from min to max:
for (int level = 0; level < 255; level++) {
digitalPotWrite(channel, level);
delay(10);
}
// wait a second at the top:
delay(100);
// change the resistance on this channel from max to min:
for (int level = 0; level < 255; level++) {
digitalPotWrite(channel, 255 - level);
delay(10);
}
}
}
int digitalPotWrite(int address, int value) {
// take the SS pin low to select the chip:
digitalWrite(slaveSelectPin,LOW);
// send in the address and value via SPI:
SPI.transfer(address);
SPI.transfer(value);
// take the SS pin high to de-select the chip:
digitalWrite(slaveSelectPin,HIGH);
}
Das ist der denn Energia drin hat.
Ich habe im anderen auch direkt SPI.begin(); eingefügt hat trotzdem nichts gebracht 
PS. Ich habe auch eine andere Libirary gefunden wo bezug auf Texas und Energia genommen wurde:

Natürlich muss man vor bei Enrf24 radio(P2_0, P2_1, P2_2); // P2.0=CE, P2.1=CSN, P2.2=IRQ
die richtigen Pins eingeben.
Jedoch hängt er auch dort:
Sender:
Sending packet: ON/OFF
Enrf24 radio transceiver status: NO TRANSCEIVER PRESENT
Empfänger:
Enrf24 radio transceiver status: NO TRANSCEIVER PRESENT
