Periodic MATLAB Callbacks - VoltageCurrent Bricklet


Recommended Posts



I am using the VoltageCurrentBricklet with MATLAB and need to collect voltage samples at a fixed (periodic) sample rate. Currently I am using a for loop but the timing is not very periodic.


    data.MyVoltageReading(loop) = hUID.getVoltage();


The MATLAB API bindings suggest a better method is to use the callback function and set a callback period to take a measurement. However, the VoltageCallback callback is only triggered if the voltage has changed since the last triggering.


Does anyone know if it's possible to configure the callback so it always returns the sample at the requested rate regardless if the reading has changed or not?


Many thanks
