The LastInDmaBuffer
class implements a kind of circular buffer.
LastInDmaBuffer
handles multiple LastInBuffer
in one data array.
The data base is an array with the data type defined by the template parameter T
. To use the LastInDmaBuffer
set the array in the constructor or by the function setData()
.
The data can be accessed by the functions
data()
to get the pointer to the data array,at()
to get the element on a specific position andThe data can be stored in the buffer by the function put()
.
