public class RdGnPiGpioDBlink extends StandardMBean implements PiUtil, RdGnPiGpioDBlinkMbean
A fifth program for Raspberry's GPIO pins Rev. 35 4.04.2021 Copyright (c) 2019 Albrecht Weinert
weinert-automation.de a-weinert.de It uses two/three pins as output assuming two LEDs connected to as H=on Pi 1 / Pi 3 Pin GPIO17/ 17 : red 11 GPIO21/ 27 : green 13 GPIO25 : yellow 22 (since Revision 45) This program forces application singleton and may be used as service. Its functions are the same as rdGnBlinkBlink (even sharing the lockFile) except for using the pigpioD library. Our makefiles define MCU and PLATFORM as make variables and macros. So we could make the GPIO pin and address assignment automatically in the C programmes. (End of original C comment excerpt)

Can be stopped by signal (cntlC), kill command and the like, as well as
by an MBean client, like e.g. JConsole, by operation stop().
