Subject: Make compile-time consts into constexpr
X-Git-Url: https://git.ljiriste.work/?a=commitdiff_plain;h=bbbdcd32b334ae649911207e496c96c17803cf28;p=Servomatic.git

Make compile-time consts into constexpr

I thought I did this in every file, but I forgot to do it in the
PressureSensor.h one. This is now rectified.
