Software Interface to Log High-Speed Data Acquired from a Stress-Strain Measuring System

Abstract

The jumping performance of a frog is determined by several characteristics of the frog. A system is developed to record the dynamic reaction force response of a striped marsh frog inserted on a platform in the propulsion phase of the jumping cycle. To record dynamic response, simultaneous data acquisition and high-speed data recording is necessary. This research paper discusses how the development of the software interface to log high-speed data is done using C. The primary objective of the system is to collect data simultaneously in a high-speed data rate. ADS1299 Analogue to Digital Converters (ADCs) is used and coupled with three strain gauges attached to the three axes of the platform. The ADC sampling is controlled by a microcontroller, and data is transferred to the PC using the serial port. The Graphical User Interface (GUI) of the software application is capable of reading, saving, retrieving, and plotting data. Besides, the software is capable of static load-based calibration and taring. The developed system is capable of recording the dynamic ground force response of an object inserted on the platform using the developed software interface. The primary objective, collecting data simultaneously at high speed, is achieved with a maximum data rate of 980 SPS. An additional option is given to calculate the jumping angle of the frog using the resultant reaction force.
