| Abstract: | A data acquisition system with 8-bit digital resolution and 8-channel analog input based on the parallel interface in MATLAB is introduced.This system with a low cost is convenient for installation and easy in use.The dynamic-link library is created by compiling the C program with the command mex,and then,the data acquisition of hardware is realized by invoking the DLL in MATLAB environment.The cooling curves of lead and wax are drawn and plotted as an example. |
