Hello guys ,
I received my pics. I replaced my receiver by 18LF2520 and transmitter by 18LF2550.
It's LF now.
I have the same result.
I receive nothing....
Is it a problem of SPI config ? |

Hi PCM,
You're right.
I had have an extra call to RF24_RX_SET().
I deleted this .
I catch the return of my function RF24_RX_SET() :
And I have an error : number 2
code of main prog :
| Code: |
#include <18F2520.h> //18LF2520 is using

void main()
{
int RXbuffer1[11];
int RXdatasize, RXpipe;
int i;
int Result;
printf("Initialisation of system in progress\r\n");
RF24_initPorts();
RF24_default_config();
Result=RF24_RX_SET(); //Receiver on
if(Result==1)
printf("Config RX Ok\r\n");
else
{
printf("Config RX KO\r\n");
printf(" Result : %d\r\n",Result);
}
printf("Initialisation of system\r\n");
while(true) {
while( RF24_RX_getbuffer(&RXpipe, &RXdatasize, RXbuffer1)!=true );
printf("Number of bytes received = %u \n\r",RXdatasize);
for(i=0;i<RXdatasize;i++)
printf("%c",RXbuffer1[i]);
printf("\n\r");
}
}

And into the function RF24_RX_SET() :
| Code: |
int RF24_RX_SET() { //Enhanced ShockBurst receiving payload(return 1 if ok, return other number if error)
int i,data;
i = RF24_comm_in(R_REGISTER|FIFO_STATUS);
if ((i&RX_FULL)==RX_FULL) return 0; //Error: RX FIFO buffer full flag, must be read before receive new packets(REVISION 1.1)
//
data = RF24_comm_in(R_REGISTER|CONFIGURATION);
if ((data&PWR_UP)!=PWR_UP) return 0x02; //Error: Turn PWR_UP on before transmit
data|=PRIM_RX; //1. Select RX by setting the PRIM_RX bit in the CONFIG register to high.
RF24_comm(W_REGISTER|CONFIGURATION, data);
/*
All data pipes that receive
data must be enabled (EN_RXADDR register), enable auto acknowledgement for all pipes running
Enhanced ShockBurst (EN_AA register), and set the correct payload widths (RX_PW_Px registers).
Set up addresses as described in item 2 in the Enhanced ShockBurst transmitting payload
example above.
*/
RF24_enable(); //2. Start Active RX mode by setting CE high.
// //3. After 130µs nRF24L01+ monitors the air for incoming communication.
/*4. When a valid packet is received (matching address and correct CRC), the payload is stored in the
RX-FIFO, and the RX_DR bit in STATUS register is set high. The IRQ pin is active when RX_DR is
high. RX_P_NO in STATUS register indicates what data pipe the payload has been received in.
5. If auto acknowledgement is enabled, an ACK packet is transmitted back, unless the NO_ACK bit
is set in the received packet. If there is a payload in the TX_PLD FIFO, this payload is added to
the ACK packet.*/
//RF24_disable(); //6. MCU sets the CE pin low to enter standby-I mode (low current mode).
// //7. MCU can clock out the payload data at a suitable rate through the SPI.
// //8. nRF24L01+ is now ready for entering TX or RX mode or power down mode.
return true; //Success
}//
