The project aims to implement a PSoC DVK based DAS system learning resource. The idea is to provide a way to develop signal acquiring basic knowledge, as well as a tool to implement simple measures. In order to do it, hardware and software have been implemented. Hardware consists of PSoC DVK, which has the functions of AC and DC signal acquiring and generating, showing information about the selected function and the acquired signal through a display, and transmitting the acquired samples through the RS-232 communication. Software allows PSoC interacting and showing the acquired samples over the time and in a histogram. The system provides the capability for selecting the ADC type between an integrating, a SAR and a dual integrating. Also, different resolutions and sample rates can be selected. This allows having several configurations in order to study some signal acquiring features, such as the interference rejection capability of the integrating ADC compared to the SAR and the analog circuit response, or to study each ADC type signal acquiring. Finally, the system allows selecting the number of samples to be acquired between some preset quantities. It allows showing a detailed temporal representation of the samples acquired. Also, the input can be scaled in order to profit the ADC resolution for small amplitude signals.
