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

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 ...

Added module lcdroutines and implemented LDC

- Moved defines from c to h ...

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

Added descriptions for the module's .h and .c files

- Included the module USART in the project ...

- Added GPL and LGPL licenses

- Updated Makefiles

Renamed functions in module integers, fixed divRoundUp(), added tests

- Moved getVoltage() to module adc ...

- Added test case class name to struct so it can be passed along with
each test case

Added testGetVoltage()

Moved some functions from lambda.c to sensors.c to make them testeable, ...

added a test

- Round up when creating moving average ...

- Added comments and doc

Added integers.h with some functions for working with integers like ...

division and rounding, use rounding to nearest in divisions for more
accuracy

Fixed tests, added comments on rounding

Rounding, fix calculation nonsense
