I need to create a driver to use with emWin so that I can operate a 1-bit per pixel Memory LCD display. The display is accessed by using SPI and any whole line of the display can be redrawn. Any suggestion as to what driver to use? It seems that a LIN driver (GUIDRV_LIN_1) assumes that the display is memory-mapped and a FlexColor driver would be too inefficient since it would use 2 bytes to represent each pixel when in fact each pixel is only a single bit (Black or White). I am familiar with how to implement a FlexColor driver since I've done this once using a color LCD display.

Is the correct approach just to use?
pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_1, 0, 0);

And then I will keep my own display buffer so that when _DrawBitmap() is called in my driver I will update the pixels in that buffer and then repaint the affected rows on the display?

Or should I use a GUIDRV_BitPlains driver? Ideally I wouldn't want to re-write every line of my display but just those lines which have changed but at least this would manage the single bit plain.
