nRF24l01 & atmega32

Postby mehdi_bm » Mon Jul 25, 2016 10:40 am

I plan to use nRF24l01 module to connect two atmega 32 uCs through RF. I used the library provided by diyembedded.com. As far as I know CE, CSN, and IRQ should be set as output, but in the tutorial accompanied with the library, it is instructed differently and the CE and IRQ should be set as input. and also nowhere in the library the pins were set.

I want to know whether anyone used the library, and if so, why these instructions are different.

It's most likely just a typo in the tutorial. CE and CSN are set as outputs, and IRQ is an input (from the microcontroller's perspective).
