//////////////////////////////////////////////////////////////// File - dalib_v11.c//// Initial code was generated by DriverWizard v6.03 - http://www.jungo.com.// The library accesses the hardware via WinDriver functions.// // Version 01 for testing the DALI Rev. B board// Version 02 implements automatic register set and trigger holdoff// Version 03 toy version for 1050MHz play// Version 04 for read1out speed evaluation// Version 05 version for interface with Pyhton// Version 06 has pedestal sub. for dalib_b3,b4,b1,b5// calib1,2,3,4 respectively. This version also allows for // multi board read out// Version 07 adding // Version 11 writes data to a time stampped file. Has problem when interfacing with GUI...
