c4272c5230 Improve lcd_write_integer_page()
The procedure `lcd_write_integer_page()` is improved by increasing the
possible values of the `comperator` variable and adding comments.

0395da78de Generate default clock signals
The "demo" from Adafruits Si5351 library is used to produce a working
proof of concept which sets PLLA to 720MHz, PLLB to 705MHz and then
Multisynth0, Multisynth1 and Multisynth2 to 120MHz, 12MHz and 13.56MHz
respectively.

c0f8cac065 Proper debouncing and dechattering
Move debouncing and dechattering to the beginning of the interrupt
service routines to handle them properly.

3aa458c4bc Furbish code and comments
Add `TODO` comment to optimize waiting times, fix capitalization in
comments, add blank line and break up long lines. To improve code
semantics `lcd_home()` and `lcd_setup()` were renamed to `draw_home()`

2579ae3686 Print actual status and data on TWI error
The contents of `TWSR` (TWI Status Register) and `TWDR` (TWI Data
Register) are printed when an error occured.

664aa4bad5 Add underscore and extend symbol lookup table
To be able to print the underscore symbol `_` the symbol is added and
the symbol lookup table is extended.
2021-09-23 22:45:46 +02:00
99175efc8c Add basic TWI support
To support basic TWI support some defines are created to keep track of
port, pins and address. Fundamental procedures such as:
- `twi_error()`
- `twi_start()`
- `twi_transmit()`
- `twi_receive()`
- `twi_stop()`
are created. Those procedures are used in `twi_read_register()` and
`twi_write_register()` which read and write data from and to registers
respectively. Lastly the TWI bit rate is set to 200kHz.

52e161f43b Create an invalid character
This character is used for invalid characters.

bd217ce6e7 Disable CKDIV8 and adapt to clock div. factor
Configure fuses for the `fuses` target in Makefile to disable
`CKDIV8`. Adapt PWM generation in `lcd_update_backlight()` to new
clock division factor, as well as interrupt handling, debouncing and
dechattering.

This also enables partially lower PWM frequencies (between off and
former lowest PWM setting) for a dimmer lcd backlight.

c48e4a31ab Use NULL instead of strlen for printing strings
This makes more sense and also removes the dependency for `string.h`.
2021-09-21 18:55:53 +02:00
47bd5e45f7 Create a function to move the cursor
Create a function (`lcs_move_cursor()`) to move the cursor in order to
reduce code repetition.

Enable all the warnings demanded by strict ISO C.
2021-09-14 00:27:09 +02:00
c53ccba034 Use symbol table for symbol parsing
Store read-only graphics and symbols in flash and use a symbol lookup
table which somehow fits to the ASCII character set. A macro is used
to make the creation of the symbol lookup table shorter. A function to
print strings enables the use of strings.
2021-09-14 00:25:43 +02:00
f9f131a6da Add static and const declarations and spaces
Add `static` keyword for consistency and `const` where it makes
sense. Also add spaces when declaring enums.

14dd301657 Fix kerning in setup screen for backlight
This fixes the inverting of the first two pixel on the setup screen
when the backlight setting is selected.
2021-09-12 01:04:10 +02:00
d75d230541 Implement contrast and backlight handling
The default values for the contrast and backlight are set when writing
to eeprom. Use the values stored in eeprom for contrast and
backlight. Update the contrast and backlight when changing their
values.
2021-09-12 00:59:22 +02:00
05c9888a75 Store setup settings in eeprom
To have the values of `value_contrast` and `value_backlight` persist
over turn offs they are loaded and stored from and in the eeprom.

For preventing the flash target from earasing the eeprom the `EESAVE`
high fuse byte is set to 0 (programmed).

The values are now loaded when booted and stored when a new value is
set in the setup menu.
2021-09-11 15:44:11 +02:00
acf4bc5754 Editable setup settings
In order to be able to change the setup settings two new setup states
are introduced `change_contrast` and `change_backlight`. All
procedures that handle the setup states are adapted to handle those
new states correct. To keep track of their values the global variables
`value_contrast` and `value_backlight` are introduced.
2021-09-11 15:36:02 +02:00
0acd0bd98b Iterable setup settings with encoder
To make setup settings configurable make it possible to select them
first. Therefore the `setup_state` enum is created to keep track of
the currently selected setting state.

e2d30d7050 Fix indents and switch syntax
Fix indentions in `spi_byte()` and add missing space after `switch`
keywords.
2021-09-11 00:21:01 +02:00
6eb515e2d4 Display digits and integers
Display digits and integers, for the later displaying leading zeroes
is supported via parameter. Demo integers are displayed in the setup
screen.
2021-09-11 00:19:59 +02:00
19c0f141a4 Add setup screen
In order to draw the setup screen, several character symbols are
added. The `lcd_setup` function, which draws the setup screen, as well
as the `update_setup` function, that updates the setup screens state,
are added.
2021-09-09 20:50:52 +02:00
9c496e765d Refactor state handling
In order to improve the handling of states the `state` enum is also
used for saving the `home_state`, which was previously called
`current_home_state`. All dependent functions were adapted to the
change.

The `volatile` keyword was added to some variables.
2021-09-09 20:40:50 +02:00
6746d34b2f Handle switch input
The `input` enum is extended with `click` and `hold` values and all
dependencies are adapted to that. In order to handle the `click` input
an interrupt is used. Further, for handling held button input with the
switch the Timer/Counter1 compare match interrupt with OCR1A is used.
