Hi,
I am following the document
http://www.semiconductorstore.com/pdf/N … RF2401.pdf
to get the 3 parts connected and working but it seems that there is more pins on
nRF2401 than in the Logic Converter mini board.
Please, could you tell me how to connect the second half?

By the way, if I only have one external SPI device (nRF2401) is it needed to add the
10K resistors?
Many thanks
Alex
When I tried the MiRF with a PIC I connected all the signals.
You do need the resistors for SPI, as the nRF2401 isn’t actually SPI-compatible unless you use them. I didn’t use them as I was bit-banging the interface.

Please, could you tell me which left lines connect to which right pins on the figure?
The transceiver has more pins available than the ones available on the logic converter
Thank you
Alex
It depends on your software. With the PIC (16F88) I just connected them like this:
CE - RA6
CS - RA0
DR1 - RA3
CLK1 - RA1
DATA - RA2
I was using the 16F88 at 3.3V, of course.

I am using atmel with the stk300 and the spi is on port b…
Alex
THe connections will be similar if you bit-bang the interface instead of using SPI. It’ll be much easier if you use a 3V AVR, as you won’t need the level conversion.
Leon
But it is a requirment to use the atmega128 and the stk300 so I have to follow the schematic and need the trully connections to not cause any damage on the 2 unique transceivers I have.
Do you think that it is better to use bit-banged than SPI clocking?
Alex
The software will be simpler if you use SPI.
Leon
ok, software is simpler using SPI because it is not needed to make a click signal by hand right, but does SPI has any disadvantage when compared with bit-banged?
Alex
No.
