7. Raspbian (raspberrypi.org image)

What is Pigpiod?

pigpiod is a utility which launches the pigpio library as a daemon. The pigpiod utility requires sudo privileges to launch the library but thereafter the pipe and socket commands may be issued by normal users.

What is Piscope?

piscope is a logic analyser (digital waveform viewer) for the Raspberry. It shows the state (high or low) of selected GPIO in real-time. pigpio needs to be running on the Pi whose GPIO are to be monitored. The pigpio library may be started as a daemon (background process) by the following command.

Is there a utility to launch the pigpio library?

pigpiod is a utility which launches the pigpio library as a daemon. Once launched the pigpio library runs in the background accepting commands from the pipe and socket interfaces. The pigpiod utility requires sudo privileges to launch the library but thereafter the pipe and socket commands may be issued by normal users.

What kind of GPIO does pigpio use?

Default PCM. pigpio uses one or both of PCM and PWM. If PCM is used then PWM is available for audio. If PWM is used then PCM is available for audio. If waves or hardware PWM are used neither PWM nor PCM will be available for audio. Default is the set of user GPIO for the board revision.

Do you need Sudo privileges to use pigpiod?

The pigpiod utility requires sudo privileges to launch the library but thereafter the pipe and socket commands may be issued by normal users. Default 6. Preferably use one of DMA channels 0 to 6 for the secondary channel

How to remotely control the GPIO on a Raspberry Pi?

Usage: use feature ‘say’; use RPi::PIGPIO; use RPi::PIGPIO::Device::ADC::MCP300x; Connects to the pigpiod running on the given IP address/port and returns an object that will allow us to manipulate the GPIO on that Raspberry Pi
