Functions to control the frequency of a demo signal.
Several of the demo signal types support setting the signal frequency, but others don't. Use tiepie_hw_oscilloscope_channel_demo_has_frequency() to find out whether the selected demo signal type supports setting the frequency.
TIEPIE_HW_API tiepie_hw_bool tiepie_hw_oscilloscope_channel_demo_has_frequency | ( | tiepie_hw_handle | handle, |
uint16_t | ch | ||
) |
Check whether the currently selected demo signal type supports setting the frequency.
[in] | handle | A device handle identifying the oscilloscope. |
[in] | ch | The channel number identifying the channel, 0 to tiepie_hw_oscilloscope_get_channel_count() - 1 . |
TIEPIE_HW_STATUS_INVALID_CHANNEL | |
TIEPIE_HW_STATUS_INVALID_HANDLE | The handle is not a valid oscilloscope handle. |
