Member Function Documentation

void otPlot.addData (  F32  data  )

Add a point to the data buffer, previous values are shifted to the right. Parameters: data  New data value to add

void otPlot.autorange (   )

Find a new min/max of the internal buffer

void otPlot.clear (  F32  val = 0.0f  )

Clear, or set a specified value, the internal buffer. Parameters: val  Value used for buffer clear, default 0

void otPlot.close (   )

Close all allocated memory

void otPlot.grid (   )

Plot the grid.

bool otPlot.init (  S16  xpos, S16  ypos, S16  xdim, S16  ydim, otGraphics *  lcdInt )

Init the class Parameters: xpos  Horizontal start position on display. ypos  Vertical start position on display. xdim  Plot width and number of samples to plot ydim  Plot height lcdInt  LCD driver Returns: True on success

void otPlot.plot (  U16  col  )

Plot with selected color the print buffer, no other operations is allowed. Parameters: col  565 coded color

void otPlot.plot (  bool  clear = true  )

Plot data on LCD. It is a high-level operation that (optional) deletes the previous plot, updates the print buffer, plot the grid and executes the data plot. Parameters: clear  If true clear previous plot

void otPlot.setData (  U32 *  data, bool  save = false )

Set new data in the buffer Parameters: data  Pointer to data buffer. save  If true save secondary buffer

void otPlot.setData (  S16 *  data  )

Set new data in the buffer Parameters: data  Pointer to data buffer.

void otPlot.setData (  F32 *  data  )

Set new data in the buffer Parameters: data  Pointer to data buffer.

void otPlot.setGridStep (  U8  step  )

Set grid spacing Parameters: step  Grid space

void otPlot.setRange (  F32  min, F32  max )

Set the plot range Parameters: min  Minimum value max  Maximum value

void otPlot.update (   )

Buffer merge.
