This routine is only available on Doors CSE 8.0 and later for the color-screen TI-84 Plus C Silver Edition.
Utility functions used when setting up an xLIBC program. real(0,0) gets the current xLIBC version, real(0,1,<bool>) turns half-resolution mode on or off, and real(0,20,<bool>) turns fast (15MHz) mode on or off.
real(0,0): Returns version in Ans
real(0,1,1): Enable half-resolution (160x240-pixel) mode
real(0,1,0,REDRAW_STATUS): Disable half-resolution (160x240-pixel) mode
REDRAW_STATUS = 1 to redraw the status area at the top of the screen, 0 otherwise.
This function will set the calculator to half h-resolution/interlaced mode. Please note that ALL xLIB drawing functions expect the calculator to be in this mode.
THIS MUST BE TURNED OFF BEFORE EXITING YOUR PROGRAM OR THE TIOS WILL BE STUCK IN THIS MODE!
Also remember to redraw the status bar up the top of the screen or the TIOS will look funny.
To disable 160 mode and redraw the status bar
(If you forget to set this mode you will see how xLIB buffers each side of GRAM. This might be useful for debugging.
real(0,2,0): Disable fast (15MHz) mode, switching to 6MHz mode
real(0,2,1): Enable fast (15MHz) mode
Note that the default CPU speed is 15MHz
VALUE defines action to take:
0 = FULL colour
1 = 8COLOUR
2 = COLOURINVERT
3 = COLOURINVERTOFF (restore to normal)
4 = FILLSCREEN
To invert the colours on the screen:
To restore the colours back to normal:
This is because inverting something twice will restore it back to normal.
To restore the colours back to normal when you don't know the previous state of the screen:
To FILL the screen (active GRAM side only) with a colour from the standard xLIB 256 colour palette:
