Hey.
Jeg har et problem med at sende de nederstående F,B,A,S signaler fra min ene nRF24l01 til den anden.

ok. Start med denne kode. (http://maniacbug.github.io/RF24/GettingStarted_8pde-example.html)

Ændre det og send nu en kommando. Det er nu ikke mere end bare et tegn "X".

char command = 'X';
void setup(void)
// Take the command, and send it. This will block until complete

Kan du modtage nu en 'X' ?

Der er et andet godt eksempel: Arduino IDE: Fil -> Eksempler -> RF24 ->led_remote

#include "RF24.h"
#include "printf.h"
// Set up nRF24L01 radio on SPI bus plus pins 9 & 10
RF24 radio(9,10);
// Radio pipe addresses for the 2 nodes to communicate.
const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };
void setup(void)
{
Serial.begin(57600);
printf_begin();
printf("\n\rRF24 communication\n\r");
printf("Wait for the next character ...\n\r");
// Setup and configure the RF24 module
radio.begin();
// Open only pipe 0 for reading
radio.openReadingPipe(1,pipes[0]);
// listen to the transmitter
radio.startListening();
}
void loop (void)
{
// Is there a new character available ?
if ( radio.available() )
{
char c;
// Read it from the RF24 module
radio.read( &c, sizeof(char) );
// And send it via the serial port to the PC (Console in the Arduino IDE)
printf("Received character: %c \n\r",c);
}
}

#include "RF24.h"
#include "printf.h"
// Set up nRF24L01 radio on SPI bus plus pins 9 & 10

/**
* Example for Getting Started with nRF24L01+ radios.

* time to the pong node, which responds by sending the value back. The ping
* node can then see how long the whole cycle took.

Hej Danni,
det virker nu.
1.)
Skitsen her http://elektronik-forum.dk/index.php?topic=756.0 er ikke rigtigt. Stikket "ICSP" er drejet 180 grader.
Jeg har tilsluttet den direkt (som her http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo):
nRF24L01 pin 5 -> Arduino D13
nRF24L01 pin 6 -> Arduino D11
nRF24L01 pin 7 -> Arduino D12
Svaret fra nRF24L01 skal se sådan ud:
STATUS = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1 = 0xf0f0f0f0d2 0xf0f0f0f0e1
RX_ADDR_P2-5 = 0xc3 0xc4 0xc5 0xc6
TX_ADDR = 0xf0f0f0f0d2
RX_PW_P0-6 = 0x20 0x20 0x00 0x00 0x00 0x00
EN_AA = 0x3f
EN_RXADDR = 0x03
RF_CH = 0x4c
RF_SETUP = 0x07
CONFIG = 0x0f
DYNPD/FEATURE = 0x00 0x00
Data Rate = 1MBPS
Model = nRF24L01+
CRC Length = 16 bits
PA Power = PA_HIGH
Hvis du har kun 0x00 er noget forkert.
2.)
Her har en ekstra 1uF kondensator mellem pin1 og pin2.
Jeg er ikke sikker på, om det er nødvendigt.

Med koden "GettingStarted" skal du sende en "T" og en "R" på modtager, fordi den starter ikke i "role_pong_back mode"
Jeg har en ny, bedre og enklere kode:
