Verified usage

Verified import paths — ran on the pinned version, not inferred.

✓ import pigpio pi = pigpio.pi()

✗ import pigpio pi = pigpio.pi('localhost')

Host parameter is deprecated; omit or use host='' for local

Blink an LED on GPIO 17. Requires pigpio daemon (sudo pigpiod) to be running.

import pigpio import time pi = pigpio.pi() if not pi.connected: print("Failed to connect to pigpio daemon") exit(1) pi.set_mode(17, pigpio.OUTPUT) pi.write(17, 1) time.sleep(1) pi.write(17, 0) pi.stop()

Debug

Known issues

gotchapigpio requires the pigpio daemon to be running before the Python script can connect. If daemon is not running, pi.connected returns False.

fix

Start the daemon: sudo pigpiod

affects: all

deprecatedPassing a hostname to pigpio.pi() or using pi.serial() may be deprecated in future versions. Use pi = pigpio.pi() for local connection.

fix

Use pigpio.pi() without arguments for local connection.

affects: >=1.78

gotchaGPIO numbers are Broadcom (BCM) pin numbers, not physical pin numbers. Common mistake is to use physical pin numbers.

fix

Always use BCM GPIO numbers (e.g., GPIO 17 is physical pin 11).

affects: all

Errors
