The sEMG (surface electromyographic) plays a significant role in the rehabilitation medicine, particularly in exoskeleton robotic treatment. A sEMG recording system using STM32F407 DISCOVERY development board and Labview software, combined with multiple signal acquisition sensors was proposed in this paper. The UC/OS-II operating system was embedded in the STM32F407 micro controller so that multiple channels can be picked up from different sensors at the same time. Due to the characteristics of STM32F407 microcontroller; the largest acquisition channels can be up to 16, and multiple signals can be collected such as the sEMG, angle trajectory, acceleration, torque etc. The use of DISCOVERY development board and Labview has reduced development cycle to a greater extent and resulted large improvement in work efficiency. |
