piscope uses the services of the pigpio library to provide GPIO timings.
By default pigpio samples the GPIO every 5µs (200 thousand times per second).
The pigpio sample rate is at most once every µs (1 million times per second). You tell pigpio which sample rate to use by a configuration option.
The pigpio daemonpigpio daemon uses the -s option to set the sample rate.
To use 1µs sampling start the pigpio daemon with the following command.
sudo pigpiod -s1
