The article presents the tests of method for real-time data acquisition from embedded systems using Matlab software. Data transmission is performed using several common use interfaces: UART/USB, Ethernet, Bluetooth and WiFi. The article includes a description of a protocol, measuring station based on two types of embedded system, implementing the proposed protocol, as well as a description of the algorithm of test programs. Experimental studies were performed using a STM32F4 microcontroller and Raspberry PI-3 single-board computer. Executed tests related: (1) the average transmission time, (2) the effective throughput of a full cycle of data exchange, (3), the required working time of Matlab to handle the transmission, and (4) the stability of the program timer used for periodic data transmission calls. Experimental studies have shown that it is possible efficient data exchange between the embedded system and Matlab while maintaining the real-time requirements.
