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)

#include "u8g2.h"
/*
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)

il3820: 200x300x1
command
0x22: assign actions
0x20: execute actions
action for command 0x022 are (more or less guessed)
bit 7: Enable Clock
bit 6: Enable Charge Pump
bit 5: Load Temparture Value (???)
bit 4: Load LUT (???)
bit 3: Initial Display (???)
bit 2: Pattern Display --> Requires about 945ms with the LUT from below
bit 1: Disable Charge Pump
bit 0: Disable Clock
Disable Charge Pump and Clock require about 10ms
Enable Charge Pump and Clock require about 100 to 300ms
Notes:
- Introduced a refresh display message, which copies RAM to display
- Charge pump is always enabled. Charge pump can be enabled/disabled via power save message
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.
LUT for the 296x128 device (IL3820)
LUT (cmd: 0x032 has 30 bytes)
section 6.8 of the datasheet mentions 256 bits = 32 bytes for the LUT
chapter 7 tells 30 bytes
according to section 6.8:
20 bytes waveform
10 bytes timing
1 byte named as VSH/VSL
1 empty byte
according to the command table, the lut has 240 bits (=30 bytes * 8 bits)
LUT / Refresh time
total_refresh_time = (refresh_lines + dummy_lines*2)*TGate*TS_Sum/f_OSC
f_OSC=1MHz (according to the datasheets)
refreh_lines = 296 (for the waveshare display, 0x045 cmd)
dummy_lines = 22 (for the upcoming u8g2 code, 0x03a cmd)
TGate = 62 (POR default, 0x03b cmd)
TS_Sum: Sum of all TS entries of the second part of the LUT
f_OSC: 1MHz according to the datasheet.
so we have
total_refresh_time = 21080*TS_Sum/1000000 = 21ms * TS_Sum
This file includes two devices:
u8x8_d_il3820_296x128 --> includes LUT which is probably from the WaveShare 2.9 Vendor
u8x8_d_il3820_v2_296x128 --> includes LUT which was optimized for faster speed and lesser flicker

Idea: SH1122 is a horizontal device, which doesn't support u8x8
However in the similar SSD1362 device, we do the correct tile conversion,
so maybe takeover code from SSD1362 to SH1122, so that SH1122 can also
support u8x8

SSD1606: 128x180x2
two-bit, four graylevels
command
0x22: assign actions
0x20: execute actions
action for command 0x022 are (more or less guessed)
bit 7: Enable Clock
bit 6: Enable Charge Pump
bit 5: Load Temparture Value (???)
bit 4: Load LUT (???)
bit 3: Initial Display (???)
bit 2: Pattern Display --> Requires about 945ms with the LUT from below
bit 1: Disable Charge Pump
bit 0: Disable Clock
Disable Charge Pump and Clock require about 267ms
Enable Charge Pump and Clock require about 10ms
Notes:
- Introduced a refresh display message, which copies RAM to display
- Charge pump and clock are only enabled for the transfer RAM to display
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.

st7305 seems to be almost compatible to the st7303, however they have a different memory architecture
https://github.com/olikraus/u8g2/issues/2436
This driver will use "u8g2_ll_hvline_horizontal_right_lsb"
--> No Hardware Flip
--> No U8x8 Support
