The STSW-OPAMP002 package includes firmware used for an electromyogram (EMG) application. The X-NUCLEO-IKA01A1 board embeds several configurations based on operational amplifiers. This software and the associated design tip (DT0061, available on shows how to configure it to develop an EMG. The application allows users to trigger an action through muscle contraction using the TSZ124 operational amplifier. The magnitude of muscle contractions can vary depending on body characteristics, therefore a calibration process has been implemented.

This application can be used for fitness, healthcare, remote control, or video games for an improved gaming experience, as well and for other activities.
