 Curve data buffer
In order to simplify the display of real-time curve, DWIN DGUS v2.0 designed a curve data buffer that is used to
cache the data of the user’s curve, which will not occupy that data space while 8 units of curves are working at the
same time.
Curve data buffer can only by word to read. Each data on the point of the curve is predicted by a 2-Byte unsigned
integer.
Curve data buffer can be accessed by Command 0x84 (only write).
