Detailed Description

Functions to control the amplitude of a demo signal.

Several of the demo signal types support setting the signal amplitude, but others don't. Use tiepie_hw_oscilloscope_channel_demo_has_amplitude() to find out whether the selected demo signal type supports setting the amplitude.

◆ tiepie_hw_oscilloscope_channel_demo_has_amplitude()

TIEPIE_HW_API tiepie_hw_bool tiepie_hw_oscilloscope_channel_demo_has_amplitude ( tiepie_hw_handle  handle,
uint16_t  ch 
)

Check whether the currently selected demo signal type supports setting the amplitude.

Parameters
[in]handleA device handle identifying the oscilloscope.
[in]chThe channel number identifying the channel, 0 to tiepie_hw_oscilloscope_get_channel_count() - 1.
Returns
TIEPIE_HW_BOOL_TRUE if setting the amplitude is supported, TIEPIE_HW_BOOL_FALSE if not.
Status values
TIEPIE_HW_STATUS_INVALID_CHANNEL
TIEPIE_HW_STATUS_INVALID_HANDLE The handle is not a valid oscilloscope handle.
TIEPIE_HW_STATUS_OBJECT_GONE
