    Hello

    Does anyone know of any library that provides functions to apply to load cell entries?

    Make an FB LowPass filter by yourself:

    vi= input
    vo_i = Actual cycle output
    vo_i-1 =Output of anterior cycle

    vo:=vi/(1+Ts)=> vo(1+Ts)=vi =>
    vo_cycle_i + T (vo_cycle_i-vo_cycle_i-1)/tCycle =vi =>

    vo_i(1+T/t_cycle)=vi+vo_i-1 *T/t_cycle =>

    vo_i= (vi x t_cycle + vo_i-1 x T)/(T+t_cycle)

    Be carefull with:

    T>>t_cycle
