2. 3 2 Acquiring Analog Input Data Before capturing data the user must first setup the correct digitizing rate determine if they re going to use external or internal trigger mode and trigger polarity After proper setup is performed you re ready to digitize When the digitize function is called the A D converter is then activated after the first trigger event and the digitized analog signal is stored into buffer RAM Data is then transferred to system RAM using another function call IMPORTANT The RAM on the AD160 is designed so that every time a sample is read out an on board address counter is automatically incremented What this means is that if the user is limited in how much data they can read out at a given time due to 16 bit DOS for example then the user can read the samples out in 16K bursts and then store the data in another location such as a solid state disk drive or specially configured memory 4 SOFTWARE DRIVERS 4 1 Introduction The primary objective in designing software drivers is to get the user up and running as quickly as possible The details on installing software drivers are listed in 4 2 xx While the listing of function calls and their parameter definitions are listed in section 4 3 xx the programming examples in section 4 4 x will show you how to include them into your programs The driver source codes are designed to work under all versions of 16 bit DOS and Linux with Kernel Code versions 2 2 x through 2
