RF-Nano Operating Instruction PDF - Pin Error!

[LK-Simon]

Page 8 of RF-NANO Operating Instruction_V.1.1.pdf contains an error in the text, which will cause endless headaches for developers trying to use the nRF24L01+ radio.
the CE and CSN pins are reversed!

D10 is CSN
D9 is CE

The manual should be updated to reflect this.

@LK-Simon Wish I knew this 3 days ago XD, althoug I still can't get it to talk to a normal nRF24L01+ module, you got any code you know for a fact works? Starting to think one of my two boards is a dud...

Hi, @S1L3NTANG3L, I actually published an article on this with a full code example project here. You can use this as a basis for your own implementation :)

@LK-Simon I followed your code but can't seem to get mine initialised?? Mind having a look at the code?
