 Bigger Bigger  Smaller Smaller  Reset Reset

Hi to all,

by this article,
http://tronixstuff.wordpress.com/2011/05/13/tutorial-arduino-and-the-spi-bus/

I understood that the SPI protocol of an Arduino (UNO/MEGA) can't work at same time with an arduino ethernet shield and aNRF24L01+ transceiver because both devices use the SPI. Also, you have to duplicate the SPI bus.

So, to avoid these problems, I think that using an Arduino Ethernet is possible to use the NRF24L01+ and the ethernet cable without problem on SPI coonection.

What do you think about this? Is correct?

Thank you in advance,
Crystal

The slave select comes into use allowing you to effectively put one or the other into slsleep mode or reduce the bus to a lower speed.

checkout sd and ethernet (same time)

Ok, but I can need that the ethernet shield and NRFL2401 must work together (the shield with a pc and the NRF with another NRF), without sleep..

What do you think about arduino ethernet and NRF24L01 solution?
