simonpauldell Posted June 17, 2015 Share Posted June 17, 2015 Hi, I'm using the LJM_eStreamStart function in DF5.91 and am wanting to clock in a stream of values at a varying rate, however this function requires explicit values? Should this configuration be done using the low level Stream functions? Thanks, Simon Link to comment Share on other sites More sharing options...
AzeoTech Posted June 17, 2015 Share Posted June 17, 2015 What do you mean a varying rate? Are you going to use an external strobe to trigger a reading? Or do you just want to be able to select a stream rate before starting streaming at a constant rate? Link to comment Share on other sites More sharing options...
LabJackSupport Posted June 17, 2015 Share Posted June 17, 2015 If you are talking about a varying external stream clock, see "Externally clocked stream" here: http://labjack.com/support/ljm/users-guide/function-reference/ljmestreamstart Link to comment Share on other sites More sharing options...
simonpauldell Posted June 17, 2015 Author Share Posted June 17, 2015 To AzeoTech Guru - I wasn't very precise with my wording: The clock is external and of a varying frequency proportional to the rotational speed of an engine. I wish this clock to keep the analogue sampling in angular synchronisation with the rotation of the engine, and as the engine speed varies so must the sampling rate. To Mr LabJack - I looked at this and thought it makes sense but will those function calls on that page work with DF as the syntax is identical to the DF functions, so will DF try to resolve the references as per its prototype for the function?
