SenseHat.Operational (PROP) ¶ PROPERTY Operational : BOOL This property has to return TRUE , when the device is configured and running
ISncDevDesc.FSpsMasterIdx (PROP) ¶ PROPERTY FSpsMasterIdx : UINT Property of type ‘UINT’ to get the master index of the F-SPS
fmod (FUN) ¶ FUNCTION fmod : LREAL This function returns the value x modulo m . It is defined as fmod(x,m) = x - floor(x/m)*m, except for m = 0. fmod has the following properties: m != 0 => x = floor(x/m)*m + fmod(x,m), m > 0 => 0 <= fmod(x,m) < m, m < 0 => 0 >= fmod(x,m) > m. m = 0 => fmod(x,m) = 0. InOut: Scope Name Type Input lrX LREAL lrM LREAL Return fmod LREAL
