Stimulation commands (from PC to the stimulation device)	Two Stimulation Levels • Mid-level: P24 generates the set frequency • Low-level: Each stimulation impulse can be generated by the control program Mid-Level • Ml_Init: Initializes stimulation • Ml_Update: contains all stimulation related parameters • Ml_Stop: deinitializes stimulation • Ml_Get_Status: Get status information and live signal Low-Level • Ll_Init: Initializes stimulation • Ll_Channel_Config: contains individual pulse shape incl. current and pulse width • Ll_Stop: deinitializes the stimulation More commands exists to get status information like battery, firmware version etc.
Typical scenario of the commands	Low-Level • Ll_init, Ll_ch_config, Ll_ch_config, …, ll_stop Mid-Level • Ml_init, Ml_update, Ml_get_status, …, Ml_stop
