My CRC16 value goes only up by one for setting /simultanous/voltage to '1' I only tested with setting this once and read the CRC16 back right away without delay.
Here is my personal notes for installing owfs from github - I hope it helps you - if you have the code you can of course skip the git-hub part In this notes I used some special parameters, which you do not have to use of course, but it illustrates that you have the ability to influence quite a number of things during configure additionally, you should not run anything as sudo - especially not untested patches - so Stefano indicated how to circumvent this easily with setting a symlink (see last line) > get owfs > > git clone git://git.code.sf.net/p/owfs/code owfs-code > > then cd into owfs-code > > ./bootstrap # an error appeared and I had to install packages > # ./bootstrap: 12: ./bootstrap: libtoolize: not found > # aclocal: not found > # pkg-config, libtool, automake > > ./configure > ./configure --disable-swig --prefix=/home/mnm/owfs/ > --program-suffix=_test85C > --with-systemdsystemunitdir=/home/mnm/owfs/systemd > > make > > make install > > ### no more running with sudo !!! ### > link owserver_<suffix> to dir /usr/bin so it can be found when > executing it with sudo > > sudo ls -s /home/mnm/owfs/bin/owserver_<suffix > /usr/bin/owserver_<suffix> On 16.08.20 21:59, Mick Sulley wrote: > > First, I noticed a typo in my mail, the CRC value increases by 8, not > 1, when I set /simultaneous/voltage.
