Syntax:
ST7920WriteCommand ( byte_variable)
Explanation:
This command writes a command to the controller.
See the data sheet for more information.
Example usage:
...
ST7920WriteCommand(0x36) ' set the graphics mode on ' <<< the ST7920WriteCommand instruction
GLCD_TYPE_ST7920_GRAPHICS_MODE = true
...Key line: ST7920WriteCommand(0x36) — sends the raw command byte 0x36 to the ST7920 controller to enable graphics mode; the following line updates the library’s
own GLCD_TYPE_ST7920_GRAPHICS_MODE flag to keep GCBASIC’s internal state consistent with the controller.
