- Include min lambda value in max measurements and vice versa ...

- Added timer1 toggling PB1 (beeper) at 1.95 kHz
- Added initial alert module

- Other symbols for display options ...

- Measure and display only every second but update the display
additionally when the menu button was pushed

Corrected wrong calculation

Refactored to use a timer interrupt polling the button instead of the ...

button triggering an interrupt, replaced the delay by a timer and
separated logging from updating the display

Use defined ADC pins in other test as well, some cleanup

Moved ADC pin defines to adc.h and use them in adc.c (DIDR) and in the ...

tests as well

Typo in comment

- Put ADC pins in sensors.h ...

- Added comments for pin assignment in "official" diagram

Added a simple "menu" (display options that show min and max ...

measurements since last start/reset) accessible through a pushbutton
triggering an PICINT interrupt. Added two modules "interrupts" and
"display", refactored code and added some tests.

Do not divide the oxygen sensor voltage by 11 before looking up the ...

lambda value but multiply the voltages in the lookup table by 11

Added TODO

- Smarter way of calculating moving average and avoiding rounding errors ...

- Use unsigned integers for voltages from ADC since they can never be
negative

Updated TODO

Formatting

- Added lambda range "Okay" ...

- Round lambda value shown on display to precision 1
- Log lambda value x1000 (max. precision)
- Remove logging of realtime measurements
- Added tests, updated some comments

Again the other USB port...

Use macros bit_is_set() and assertTrue()

Pins not ports

Removed license, really not necessary for such a project

Improved comment

Removed DIDR todo

DIDR! + tests

Added "assert" for sei() to test

- Set ADC clock prescale to 8 (125 kHz at 1 MHz CPU clock) ...

- Let measure() return measurement that can be called to display()
instead of measure() calling display() (for testability)
- Removed semicolons from #defines
- Include stdbool.h and use bool instead of uint8_t
- Added tests
- Some formatting, comments

- Multiply values by 16 for better precision calculating the average ...

- Added/improved some related tests

Added additional logging of unaveraged measurements for ...

testing/evaluation

- Update attribution with module lcdroutines ...

- "Improved" .h files

Added module lcdroutines and implemented LDC

- Moved defines from c to h ...

- Updated programmer port to /dev/ttyACM0 in Makefiles
- Use divRoundNearest()
