| Abstract: | A method of synchronous realization of A/D sample and serial communication on PC/104 is introduced.This paper discusses how to compile VxD to capture the PC104 interrupt request to sample,and compile the WIN32 program to communicate with VxD by VC 6.0 and VtoolsD;How to compile the serial communication code by the CSerialPort class,a free tool,succeed in the synchronous realization A/D sample and serial communication by the synchronization of thread.The key program codes are given. |
