Abstract：In order to meet the real-time collection of sensor signals by edge controllers,a 16 bit 8-channel analog data acquisition module based on FreeRTOS is designed.This module uses the STM32F103 microcon-troller as the main controller,and implements data acquisition and analog-to-digital conversion around the AD7606 chip.It flexibly manages and schedules tasks using the FreeRTOS real-time operating system,and quickly and accurately sends the converted data to the edge controller.The experiment ias conducted on a cer-tain edge controller device,and the results showed that the module had good performance,small errors,high accuracy,and met the design requirements.
