 Hello, good evening everyone. I am Vasudha and I have been working on accessing DAC cards through SyLab this summer. So basically DAC cards are data acquisition devices. They provide the interface between a signal and a computer so that we can use the signals to perform measurements and control the device. So we need DAC cards to automate the control of the device and to sample signals and get the measurements. This project, we needed this project because all these DAC cards where most of them were manufactured by these companies such as AdLink, NI and Advantec and they provided the interface through their own software such as LabView. So this came at a separate cost. So this is just against the principles of open source and we, as usual, we would like to make it all available open source. So we try to access these cards through SyLab. So the available cards were NIUSB6008, AdLink PC9-112 and Advantec-1711. So NIUSB6008, it's a simple low-cost DAC card that could be used for performing simple lab experiments. So NI provides an interface through its drivers called NI-DAC-MX base. So the problem with this is that it was only... Can you come to your work rather than explaining the cards? Yeah. So we were on the lookout for a good DAC, like how to access this card through SyLab. So we found a way to do that through the visual basic CAPI reference which could be accessed through a wrapper in SyLab. So I have a demo. So this is the DAC card and it has been connected to a shield. So this is a push-button interface. So when I press it, there is an output, as you can see.
