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>
