-This page is a work in progress.
-Progress on reverse engineering the Pro nRF Shield so far:
-Pins:
-{{:digispark:tutorials:nrfmodule.jpg?600|}}
-Assembled:
-{{:digispark:tutorials:evernote-camera-roll-20141125-143604.jpg?600|}}
-Stacked Up and Ready to Go:
-{{:digispark:tutorials:evernote-camera-roll-20141125-143141.jpg?600|}}
-Dependencies:
-Use the [[https://github.com/maniacbug/RF24|RF24]] library to control the module. You can [[https://github.com/maniacbug/RF24/archive/master.zip|download the latest version here]]. Copy the contents of the zip to your libraries directory.
-Sketches:
-You'll need two Digispark Pros with nRF modules to execute these sketches. Select one Digispark to be the sender and load this code:
-<code>
-#include <SPI.h>
-#include "nRF24L01.h"
-#include "RF24.h"
-RF24 radio(9,12);
-const int LED = 1;
-const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };
-// The various roles supported by this sketch
-typedef enum { role_ping_out = 1, role_pong_back } role_e;
-// The role of the current running sketch
-role_e role = role_pong_back;
-void setup() {
-  // put your setup code here, to run once:
-  pinMode(LED, OUTPUT);
-  digitalWrite(LED, LOW);
-  radio.begin();
-  radio.setRetries(15, 15);
-  radio.openWritingPipe(pipes[1]);
-  digitalWrite(LED, HIGH);
-}
-void loop() {
-  unsigned long value = 2000;
-  bool ok = radio.write(&value, sizeof(unsigned long));
-  if(ok) {
-    digitalWrite(LED, LOW);
-    delay(2000);
-    digitalWrite(LED, HIGH);
-  }
-}
-</code>
-The other Digispark should be the receiver. Upload this code:
-<code>
-#include <SPI.h>
-#include "nRF24L01.h"
-#include "RF24.h"
-RF24 radio(9,12);
-const int LED = 1;
-const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };
-// The various roles supported by this sketch
-typedef enum { role_ping_out = 1, role_pong_back } role_e;
-// The role of the current running sketch
-role_e role = role_pong_back;
-void setup() {
-  // put your setup code here, to run once:
-  pinMode(LED, OUTPUT);
-  digitalWrite(LED, LOW);
-  radio.begin();
-  radio.setRetries(15, 15);
-  radio.openReadingPipe(1, pipes[1]);
-  radio.startListening();
-  digitalWrite(LED, HIGH);
-}
-void loop() {
-  if(radio.available()) {
-    unsigned long value;
-    bool done = false;
-    while(!done) {
-      done = radio.read(&value, sizeof(unsigned long));
-      delay(20);
-    }
-    digitalWrite(LED, LOW);
-    delay(1000);
-    digitalWrite(LED, HIGH);
-  }
-}
-</code>
-Now, when both units are powered up the LEDs on both should start blinking. If either is unplugged then the LED on the other will revert to solid on.
