FreeCAD update

Correction of manuals ...

- average power consumption 30µA
- operating time about 3 years
- display resolution 250x122 pixel

Update Makefile ...

...so project builds with GCC 14 on current Debian Linux

Update estimated average power consumption ...

Guessing 3 years with about 3.9V after 20 months and 4.8 -> 3.0V

update to KiCad 7.0, add PDF for schematic and PCB (#47)

add STEP for whole frame, update PDF (#46)

update NetBeans project configuration

make pointed-to objects const that are not supposed to be changed (#45)

set frame in SRAM sequential mode, saving more power (#43)

more optimizations on types (#41)

add types.h to Makefile

fix typo, add types.h to Makefile

put shared types in 'types.h' (#40) ...

* put shared types in 'types.h'

More optimizations (#39) ...

* use 'typedef uint8_t code_t' for char codes instead of uint16_t
* use 'typedef uint8_t height_t' for bitmap height instead of uint16_t, same for width, row, col
* optimize writing strings to and reading strings from SRAM (not used)
* delay initial display update after power on (not necessary but avoids two consecutive display updates when connecting the programmer (display update starts almost immediately after power on and restarts when programmer resets after ~1 second))

Let watchdog wake up MCU only every 8 instead of 1 seconds, saving some power (#38) ...

- set watchdog to bark every 8 seconds
- counter can now be 8 instead of 16 bit - ATOMIC_BLOCK not needed
- adjust constant and variable names
- saves about 4uA in average power consumption

avoid frequent, expensive divisions (#37)

compile with -O2 instead of -Os as this seems to save a few microamps

remove unnecessary delays in display initialization (#36) ...

- no need to wait 10ms since VCI already supplied, display is in deep sleep mode
- no need to wait 100ms after hardware eset (waiting for busy) before software reset

=> might contribute to a tiny reduction of power consumption

update project ...

- use self-hosted runner with avr-gcc 13.2.0

update project ...

- set --param=min-pagesize=0
- ugly hack in project configuration to avoid issues in code assistance with __flash qualifier

Merge pull request #33 from gitdode/makefile ...

Problems with Makefile

add dependency on .h files and Makefile

replace '-Wl,--relax' with '-mrelax' in Makefile

Update README.md
