MUIF (Monochrome User Interface Functions)
n: A number 0 to 9 without any quotes, e.g.: 5
id: Exactly two characters or numbers in double quotes, e.g. "G5".
cb: A callback function with the following prototype: "uint8_t muif_cb(mui_t *ui, uint8_t msg)"
There are MANY predefined callback functions, see separate list
var: Address of a variable.
text: Normal text, but special characters might be required for some callback functions, for
example the text might contain a list of selectable elements separated with the '|' symbol.
MUIF_STYLE(n,cb)
Corresponding FDS command: MUI_STYLE(n)
Change the style of any other elements after MUI_STYLE(n), does not draw anything
MUIF_RO(id,cb)
Corresponding FDS command: MUI_DATA(id, text) MUI_XY(id, x, y), MUI_XYT(id, x,y,text), MUI_XYA(id, x,y,a), MUI_XYAT(id, x,y,a,text)
Places a read only element on the form.
The correct FDS command depends on the callback function.
MUIF_LABEL(cb)
Corresponding FDS command: MUI_LABEL(x,y,text)
Places a text at the specified position, similar to MUIF_RO
MUIF_GOTO(cb)
Corresponding FDS command: MUI_GOTO(x,y,n,text)
Places a button at the specified position, similar to MUIF_BUTTON, but does not require an ID.
MUIF_BUTTON(id,cb)
Corresponding FDS command: MUI_XY(id, x, y), MUI_XYT(id, x,y,text), MUI_XYA(id, x,y,a), MUI_XYAT(id, x,y,a,text)
Places a selectable element on the form.
MUIF_VARIABLE(id,var,cb)
Corresponding FDS command: MUI_XY(id, x, y), MUI_XYA(id, x,y,a)
Places a user input element at the specified location.
The correct FDS command depends on the callback function.

MUIF_U8G2_LABEL()
replacement for MUIF_LABEL(mui_u8g2_draw_text),
used by MUI_LABEL(x,y,"text")
Supports UTF8
MUIF_U8G2_FONT_STYLE(n, font)
A special u8g2 style function, which replaces MUIF_STYLE, but restricts the style change to the
specific font argument (however, this should be good enough in most cases).
As usual, the style "n" can be activated with MUI_STYLE(n) in FDS.
Example:
muif_t muif_list[] MUI_PROGMEM = {
MUIF_U8G2_LABEL(),
MUIF_U8G2_FONT_STYLE(0, u8g2_font_5x8_tr)
};
fds_t fds[] MUI_PROGMEM =
MUI_FORM(1)
MUI_STYLE(0)
MUI_LABEL(5,12, "5x8 Font")
;

Limitations:
- Only available in full buffer mode (will not do anything in page mode)
- Tile positions and sizes (pixel position divided by 8)
- Any display rotation/mirror is ignored
- Only works with displays, which support U8x8 API
- Will not send the e-paper refresh message (will probably not work with e-paper devices)

Description:
Draws normal or inverted text with optional frame around text.
The text (and the frame) can be horizontally centered around the provided reference position.
This procedure will use the current draw color and current font. The height of the frame
depends on the setting of setFontRefHeightText(), setFontRefHeightExtendedText() or setFontRefHeightAll()
Note 1: drawColor 2 (XOR) is not supported. Result will be broken with draw color 2.
Note 2: This procedure will enforce font mode 1 (transparent mode)
Note 3: Some fonts may add an extra gap on the right side. This is a font problem and can not be avoided (for example inb16 has this problem).
The height of the button is defined by the current font and
setFontRefHeightText,
setFontRefHeightExtendedText
setFontRefHeightAll
Right padding might be influenced by the font.
For example u8g2_font_inb16 may add an extra pixel gap (increase padding by one)
on the right side.
The current draw color is considered, but only draw color 0 and 1 are supported
This function requires transparent font mode: setFontMode(1)
Side effect: Font transparent mode is enabled setFontMode(1)

This will sent the display init message to the display.
The display itself will then call u8x8_d_helper_display_init() from above. This includes:
GPIO Init (set port directions)
BYTE init (part of CAD init: which may set some levels)
CAD init (which will set things like I2C default address)
Issue a reset to the display: This will usually turn off the display
Additonally each display will set the init code to the display, which will also turn of the display in most cases (Arduino code disable power save mode later)
Actually this procedure should be better called InitInterfaceAndDisplay, because it actually does both.
(actually u8x8_InitInterface() is not called directly but only u8x8_gpio_Init and u8x8_cad_Init which
in turn is called by u8x8_InitInterface())
InitDisplay is called by the Arduino begin() function
In some cases it is not required to init the display (for example if the display is already running, but the controller comes out of deep sleep mode).
Then InitDisplay can be skipped, but u8x8_InitInterface() (== u8x8_gpio_Init() and u8x8_cad_Init()) need to be executed.
