hi i want to interface the mrf24j40ma module with my arduino nano , im trying this library out mrf24j40ma arduino library - SparkFun Electronics Forum

the programs compile properly , but the arduino dosent respond when the program is burnt into it , i did some experimentation and found that the problem was the initialization of the mrf24j object , i tried checking online and found this

in the last post he was talking something about the ss pin that was the problem , on checking the datasheet for the mrf24j40ma i din see any ss pin for the module , can someone help me please

This one?

im trying this library out

That library uses SPI.

with my arduino nano

http://arduino.cc/en/Main/ArduinoBoardNano

SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.

I think you need a different kind of Arduino.

hey i found this article , so i can use spi by toggling the i/o pins using digital write ?

Yes. It's called bit-banging, but it works.

5

just for information sake , can i use the shiftIn and shiftOut functions too as it provides the clock timing

ive also tried the bit banging method which did not work , can someone suggest something to help me get things working?

How do you know data was not sent?

There could be many problems with your setup - both hardware and software. We need to see a schematic of how you have attached the radio to the sender, and the code on the sender. We need to see a schematic of how you have attached the radio to the receiver, and the code on the receiver.
