Member Function Documentation

add_table()

template<uint16_t TableSize, uint8_t MaxTables = 8>

bool sbl::widgets::source::ScanningOsc< TableSize, MaxTables >::add_table ( const float *  table )

inline

Note

All public methods are ISR-safe — bounded computation, no I/O.

Parameters

table

Pointer to float table data (must have guard points)

Returns

true if added, false if at capacity
