RT-Linux for a torque testing stage


In this paper the use of real time linux for data aquisition and control of a micro mechanic torque testing stage is presented. More precisely, a real time linux kernel module is in charge of real time tasks taking values from a DAQ board, saving values to shared memory and vice versa. The communication with the user space application is done by means of FIFO buffers passing control and event messages. The GTK+ based graphical user interface itself presents measured date and periodic signals to be output to the micro motor.
