pigpio is a C library for the Raspberry which allows control of the
General Purpose Input Outputs (GPIO).
**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.**
## Features
* Sampling and time-stamping of GPIO 0-31 between 100,000 and 1,000,000 times per second
