nRF2401 connections

Hi,

I was wondering if this is the right connection diagram for using nRF2401

sensor.

Thanks for your inputs.

It’s completely wrong. Look at the SFE code samples.

No. I connected as the sample code has shown.

They are RF transceivers. So I connected like this.

On sample code, it defines as

#define TX_CE PORTBbits.RB0
#define TX_CS PORTBbits.RB1
#define TX_CLK PORTBbits.RB3
#define TX_DATA PORTBbits.RB4

#define RX_CE PORTAbits.RA2
#define RX_CS PORTAbits.RA3
#define RX_CLK PORTAbits.RA4
#define RX_DATA PORTAbits.RA1
#define RX_DR PORTAbits RA0

Here are the connections I use:

;CE - RA6 output

;CS - RA0 output

;DR1 - RA3 output

;CLK1 - RA1 output

;DATA - RA2 input/output

You only need one set of I/Os. The example has two nRF2401s connected to the same PIC.

Ah… maybe it’s a different sample code.

So I have my RF pins in correct position, right?

Thanks leon.
