A problem showed up. It says
"A #DEVICE required before this line"
it meant for this lines :
| Code: |
enum {
R_REGISTER =0b00000000, //*bits from 0 to 4 are the addresses to be read(0 a 31)//Read command and status registers.
W_REGISTER =0b00100000, //*bits from 0 to 4 are the addresses to be write(0 a 31)//Write command and status registers. Executable in power down or standby modes only
R_RX_PAYLOAD=0b01100001, //*Read RX-payload: 1 – 32 bytes. A read operation always starts at byte 0. Payload is deleted from FIFO after it is read. Used in RX mode.
W_TX_PAYLOAD=0b10100000, //*Write TX-payload: 1 – 32 bytes. A write operation always starts at byte 0 used in TX payload.
FLUSH_TX =0b11100001, //*Flush TX FIFO, used in TX mode
FLUSH_RX =0b11100010, //*Flush RX FIFO, used in RX mode. Should not be executed during transmission of acknowledge, that is, acknowledge package will not be completed.
REUSE_TX_PL =0b11100011, //*Reuse last transmitted payload. TX payload reuse is active until W_TX_PAYLOAD or FLUSH TX is executed. TX payload reuse must not be activated or deactivated during package transmission.
R_RX_PL_WID =0b01100000, //*Read RX payload width for the top R_RX_PAYLOAD in the RX FIFO. Note: Flush RX FIFO if the read value is larger than 32 bytes.
W_ACK_PAYLOAD=0b10101000, //bits 0 to 2(value 0 a 5) Used in RX mode. Write Payload to be transmitted together with ACK packet on choosen Pipenumber(0 to 5). (Pipenumber valid in the range from 000 to 101[0d0 a 0d5]). Maximum three ACK packet payloads can be pending. Payloads with same pipenumber are handled using first in - first out principle. Write payload: 1– 32 bytes. A write operation always starts at byte 0.
W_TX_PAYLOAD_NOACK=0b10110000,//*Used in TX mode. Disables AUTOACK on this specific packet.
NOP =0b11111111}; //No Operation

has anyone faced such a problem ?
Here are some heads-up maybe you can figure out the problem
I'm using
PIC 18F2550 and PIC 18F2455
Crystal of 8 M
I need the pins to be as the following :
| Code: |
#define TX_CE PIN_B0
#define TX_CSN PIN_B1
#define TX_SCK PIN_B3
#define TX_MOSI PIN_B4
#define TX_MISO PIN_B6
#define TX_IRQ PIN_A0

I believe I have a problem with Compiler, code or anything else.
Or I have to set the PIC.
I have been working on this code for almost 48 hours, NOTHING worked.
Can anyone help please ?
If any could every used the Eduardo's library. Upload it on a website and send me the link. The copy and paste of the code doesn't seem to work.
or do I have to throw away the chip ? |

| It probably means that the first thing in your code isn't the #include for your chip or that you are trying to do multiple file compilation and not providing the #include for your chip for each module. |

First of all I like to thank everyone specially Eduardo.....
I cannot make your code work !
I have read the datasheet and from frustration I come up with this working solution, this code will transmit and receive, my hardware are ok, the PINout fine.....It just to prove that works, I don't even need the darn thing's...it just happen to be so cheap I bought 10 of them...

Thank you all,
The library has been compiled correctly.
^_^ I'll be working on sending texts. Tonight |

I need a small example to send "123" from the sender
and receive it out on an LCD. |

dezso,,,,
Your code seems to be for the Receiver..
The function Transmit_data was never used |

Yes you are correct, the posted code is to receive.
I can post my transmit code later today, basically the config different and txdata send 4 byte
bb_xfer(0x34);
bb_xfer(0x33);
bb_xfer(0x32);
bb_xfer(0x31);
You can create a for-loop with array to send whatever wanted.

I would be very greatful to have the Transmitter code, I bit, it's not very different from this one.
If you don't mind, giving a small example, of sending 123 only. |

| help to use the RF module |
| Posted: Thu Apr 04, 2013 2:16 pm |
|
|
hello for all, i wrote here, because i have a pair of these RF modules, and i need them to make some kind of robotic super controller, reading 6 analogs sticks and 14 buttons... also i need some feedback from the robot (example: there's several impact sensors mounted on the robot, when the robot is hit in one or more of those sensors, i need to make the controller to vibrate) just the same way like the play station or the xbox controller does.
I'll use a pic 16f877A in the robot, and the pic 16f876A in the controller.
the robot will have two rc standard servos modified to move a pair of wheels for locomotion, and it will have 2 more servos to move an on board camera and the other 2 servos to move a small air-soft gun. the rest of the 14 digital outputs can be used to lighting, turning on and off the air-soft gun, and other functions. the other pins are used to connect the impact sensors.
I've found something, but the problem are that all those projects are based on arduino, and other projects use those expensive xbee rf modules.
I've read all this topic, but i can't find something far nearly to the project I'm trying to do 
 I'll start to test the modules then start to modeling the project based on this awesome driver created by Eduardo__.
ill be post here as any troubles or request pops out.
thanks in advance for the future help...  |

ok hararion.
Please, look at this topip from beguining. I´ve used with success this driver in PIC18F876A(it´s very near to PIC16F877). I used Hardware SPI

The short code from deszo posted March 8, 2013 works great !!!
There's a small error that may cause some confusion when you try to port the code to another processor or different pins...
Toward the end in the receive section is a line: which should be | Code: | | if(!input(RF24_IRQ)) |
instead.
It also helps to set up a #define for PIN_A0, for example: | Code: | | #define LED0 PIN_A0 |
and replace all occurrences of PIN_A0 with LED0.
You can get these modules with the PCB trace antenna for as little as $2 from eBay and my test from one upstairs corner of my house to an opposite corner downstairs works great.

Thanks a lot showing us your results Mr. jgschmidt.
What are the uCs that you used in your experiments with this driver?
Regards.
