953649725b Remove colon from "BACK" setup menu entry 
Rename "BACK:" to "BACK" in setup menu.

dada6fe5d4 Allow to print larger integers 
Use `uint32_t` instead of `uint8_t` when printing integers with
`lcd_write_integer_page()`.
 2021-09-24 23:39:56 +02:00
finga
22095d6e78 Pass kerning when writing string 
In order to be able to print more compact strings also pass the
kerning parameter to `lcd_write_string_page()`.
 2021-09-24 23:39:27 +02:00
finga
a34a58535b Improve and add symbols 
Add symbols for `D` and `M` and improve `U`.
 2021-09-24 23:19:02 +02:00

45bfe04537 Also move and rename drawing the splash screen 
For consistency `lcd_splash()` was moved before `draw_home()` and
renamed to `draw_splash()`.

144da8d7f2 Add flag to invert output of twi_error() 
This is only for convinience for the eye to be able to print
"debugging" information not inverted.

2beecbe722 Move shifting of TWI slave address 
As this may be obscure the shifting of the TWI slave address is moved
to where it is used instead of where it is set.
