Code and example usage of the Pypi NRF24 module. Cleaned up and added support for reading from multiple pipes using open_reading_pipe(pipe, address) and open_writing_pipe(address) in order to be more "compatible" with the way NRF24 is used on Arduinos.

pigpio is a library for the Raspberry which allows control of the
|
||||
General Purpose Input Outputs (GPIO). pigpio works on all
|
||||
versions of the Pi.
|
||||
<p><b>At the moment pigpio on the Pi4B is experimental. I am not
|
||||
sure if the DMA channels being used are safe. The Pi4B defaults are
|
||||
primary channel 7, secondary channel 6. If these channels do not
|
||||
work you will have to experiment. You can set the channels used by
|
||||
the pigpio daemon by invoking it with the -d and -e options, e.g.
|
||||
<small>sudo pigpiod -d 5 -e 8</small> to specify primary 5,

secondary 8.</b></p>
