Hi deszo,
What means "PSup 3.6v" ?
You must supply it below 3.6V.
I´m using Mplab 8.7 yet. I´ve a program using this driver for several days(I´m using 2 NiMH batteries, suplying 2.4V). It transmits each 10s and then it sleeps. It is several days and it not reseted or stuck yet.

This is just so strange..
Firs and second pic show the SPI com with the driver from the link in my previous post.
Third pic show your PIC16F876A test, don't understand why SPI behave this way. Both setup use Hardware SPI, so the SDI/SDO/CLK cannot be messed up..CE&CS set up as described, PIN_C1/C2
Generally I don't use a lot of 3.3v device, my bench got 5v output so I just used a 317 v-reg with fixed res to 3.6v, now its changed to 3.3v, that did not fixed it tho.

Try to configure SPI to use software instead of pic hardware.
I´ve have little problems with hardware SPI in some CCS C versions.
Then, check it again.
thanks
Eduardo

Can't explain it !!
Change it to software spi and worked than change it back to HW and worked again !!

It´s simple:
| Code: |
if ( RF24_RX_getbuffer(&RXpipe, &RXdatasize, RXbuffer1)!=true ) {
//Congratulations, you receive data
//Read data from RXbuffer1 and use it as ou want
//So RXbuffer1 contains the data(pointer or array),
//RXdatasize contains datasize(1 to 23 bytes) and
//RXpipe contains the number of the pipe that you
//received the data, as each nRF24 pipe has one
//different address that you can change(nRF24
//has 6 pipes, pipe 0 to 5)
}
|
You must to check whether you received any data from RF and use it in your program.
I usualy check it several times a second.
As nFR has triple 32bytes buffer, you´re able to receive up to 3 packets without PIC CPU intervention. If you receive 3 packets, your nRF24 buffer is full and you´re not able to receive more data if you not read it using the example above.
Good luck.

have you tried to use example programs? Try with example progams first as I´ve already tested them.

I didnT try with 16f628 and 16F876 as your example but I though that I can work with 18F too.
the first point is that, when I use the "ICD=TRUE", my fuses closed by complier. so I deleted this code but still I cannot receive any data. actually, I donT know tranciver is work true or not.
I have used your same code in examples.just as differ, defined the pins as 18F.
How can I be sure, my tranciver is working or not? |

See previous page in this topic. Look for RF24_check_config() function.

Here's my setup code for an 18F device which works well with Eduardo's code unchanged.

//#define RF24_USE_DMA //nRF24 uses SPI DMA for multiple byte transfers(I´m using Hardware DMA)
#define RF24_SPI STREAM_SPI//Redirects SPI2 port to RS24_SPI stream
#define RF24_SPI_DISABLE_WARNING
#define LED PIN_A0

#define Led_On() output_high(LED)
#define Led_Off() output_low(LED)
#define mFlashLED {Led_On(); delay_ms(150); Led_Off(); }

thank you. I am still working on it.
1-)Hexadec,in your code,
#USE SPI(SPI1, MASTER, BAUD=1000000, MODE=0, BITS=8, MSB_FIRST, STREAM=RF24_SPI)
is give me an error and I changed it like this:
#USE SPI(SPI1, MASTER, BAUD=1000000, MODE=0, BITS=8, MSB_FIRST, STREAM=STREAM_SPI)
the error is fixed. I cannot understand that, this code works on your 18F4550 but not work my 18F4520. what is the reason?
2-)I am using this mini kit at the picture.
is the pin configurations right?
3-)I connected the pins directly to the microcontroller.is this right?

The STREAM= is only naming the stream for the protocol.
What error message do you get and have you defined RF24_SPI?
The pinout you show is the same as the modules I am using.
Have you noticed that the pin configuration is:-
2 4 6 8
1 3 5 7
The pins are connected directly to the MCU |
