sub procedure SPI_Glcd_Image(dim const image as ^byte)
Returns
Nothing.
Description
Displays bitmap on Glcd.
Parameters :
-
image:
image to be displayed. Bitmap array can be located in both code and
RAM memory (due to the mikroBasic PRO for AVR pointer to const and
pointer to RAM equivalency).

Use the mikroBasic PRO’s integrated Glcd Bitmap Editor (menu option Tools ›
Glcd Bitmap Editor) to convert image to a constant array suitable for display-
ing on Glcd.

Requires
Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routines.
