Analog Output Circuit
The circuit utilized for the analog output is below:
Sample Software
- Open the DAC_k3.slx sample model in MATLAB/Simulink. Change the initial value of AO1 and/or AO2 to a voltage between 0 and 5 V.
- Build the model (Ctrl + b).
- Flash FlexCase with generated binary (DAC_K3.bin).
- Open FreeMASTER connection and assign symbol file (DAC_k3.elf) to project. Add variables AO1 and AO2 to variable watch, then modify values to desired voltage level.
