The monochrome display is 96x64 pixels. KnightOS programs are expected to allocate a 768-byte buffer of memory, and place the address in IY (allocScreenBuffer does this for you). You may use fastCopy to copy this buffer to the display. This page documents monochrome functions. For the color display, see color.
Copies the screen buffer to the LCD.
This routine will return immediately without drawing to the LCD if the calling thead does not have an LCD lock. Acquire one with getLcdLock.
On a TI-84+ CSE, this routine will draw the 96x64 monochrome buffer (the "legacy" buffer) to the LCD. The LCD should be set to legacy mode (see setLegacyLcdMode).
