DLL to calculate the result Each parameter passes both scaled and raw data There are also constants that are passed into the function DLL to allow the function to operate in different modes Client functions are solved at the processing rate defined in the options the default is when stream 1 receives new data The user may wish to have some interface between LDPS and another program or to some external device like a network serial port etc Client functions allow one to connect to basically any hardware and or software and to pass any data needed An example of this scenario could include driving an antenna to point to a specific spot in the sky based on the latitude longitude and altitude of data collected from the telemetry stream With normal parameters the text is limited in how it 1s displayed This involves either picking the number of decimal places or by using enumeration This usually suffices except if one wishes to display an angle with degrees minutes seconds or time with hours minutes seconds With a function the resulting value displayed may be a string created by the function and may take on any format desired In LDPS client functions operate in one of two modes As a normal function the DLL solves for the data and returns the value to be displayed in a widget The alternate mode does the same thing except it also allows the function DLL to draw on the screen This allows developers to hook their own wi
