 I prefer directly writing in the registers as described in the [[http://www.atmel.com/images/Atmel-8271-8-bit-AVR-Microcontroller-ATmega48A-48PA-88A-88PA-168A-168PA-328-328P_datasheet_Complete.pdf|datasheet]] rather than using an [[https://www.arduino.cc/en/Main/Software|abstract IDE]] and [[https://github.com/TMRh20/RF24|libraries]].
 This way I learn how it works in details.
