Included software:



(1) PC test software for Windows 7 64-bit (32-bit compatible);

(2) SDK and sample program and driver interface for Windows (dll library link file, which can be directly called by labview, and the library file function is specified by the user);

(3) The software can output txt files, (database files, which belong to the software function can not be added)





Note:

(1) The internal FPGA can average the collected data curve for a specified number of times and output the result (average number 0-32768 can be set).

(2) Reserve FPGA debugging ports and some resources, allowing users to write algorithms and debugging by themselves.
