This is a second simple GPIO pin output program using pigpio(d), as does gnBlinkSimple.c. Additionally, it has features qualifying it as a process control service. It locks gpio, it can run endlessly and it cleans up when ended. Hence, it may be the germ cell of of simple real time control applications.

Compile on Pi by: gcc -lpigpiod_if2 -I./include -o rdGnBlink rdGnBlink.c gcc -lpigpiod_if2 -I./include -c -o weRasp/weLockWatch.o weRasp/weLockWatch.c gcc -lpigpiod_if2 -I./include -c -o weRasp/sysBasic.o weRasp/sysBasic.c

Compile on Windows by:

arm-linux-gnueabihf-gcc -DF_CPU=1200000000 -DPLATFORM=raspberry_03 -DMCU=BCM2837  -DTARGET=Pi4all  -I./include    -c -o rdGnBlink.o rdGnBlink.c
arm-linux-gnueabihf-gcc -DF_CPU=1200000000 -DPLATFORM=raspberry_03 -DMCU=BCM2837  -DTARGET=Pi4all  -I./include    -c -o weRasp/weLockWatch.o weRasp/weLockWatch.c
arm-linux-gnueabihf-gcc -DF_CPU=1200000000 -DPLATFORM=raspberry_03 -DMCU=BCM2837  -DTARGET=Pi4all  -I./include    -c -o weRasp/sysBasic.o weRasp/sysBasic.c
cp  rdGnBlink.elf rdGnBlink
winscp.com /script=progTransWin /parameter sweet:0123  targetPi bin  gnBlinkSimple

or better by using make:

make PROGRAM=rdGnBlink TARGET=pi4play clean all
make PROGRAM=rdGnBlink TARGET=pi4play progapp  

If not having made the usual lock file for pigpiod do

touch ~/bin/.lockPiGpio
