adjusted rules: wait longer for oxygen sensor to be heated up and give ...

it more time to heat up, time out the sensor heater after 15 mins if
there does not seem to be a fire, switch the heater on if it is off and
not faulted and it seems obvious there is a fire burning, decreased the
min. temp the oven is expected to reach to 700°C, consider the fire
burning if it either reached that min. temperature or if lambda is below
2.

use enums instead of constants, rename "heating" to "heater"

moved button, beeper and heater pin settings to pins.h, maintain airgate ...

position in rules, added "tooLean" rule, show fire "direction" together
with current measurements

adding tests + some minor cleanup and improvements

added/improved/fixed some tests, some related small fixes and ...

improvements

completely avoid using lcd_clear() since it sometimes garbles the ...

display, set HEATING_READY_MA to 1400 - at 1500 it is not fully warmed
up

added menu item/display position showing oxygen sensor heater current

compensate ADC non-linearity, update measurements also when heating is ...

off, added some comments

fixes and improvements for oxygen sensor heating control

experimental implementation of rules to notify about certain conditions ...

during burndown

- use size_t ...

- added tests
- some small improvements

- made function parameters readonly ...

- types with capital first letter
- updated comments and documentation

- use program space for unit test instances instead of data space ...

- "private" variables static
- removed updateDisplay()
- renamed some functions

finally updatePending is set at the right time so display is always ...

updated immediately

- Set and cancel alerts ...

- Display text
- Receive USART data
- Simulation by sending measurement values via USART
- Added some commands like enabling and disabling simulation
- Some refactoring and renaming of functions
- Comments missing
- Tests missing

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

tests as well

- 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.

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

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

- 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

Removed license, really not necessary for such a project

- 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

- Update attribution with module lcdroutines ...

- "Improved" .h files

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

- Included the module USART in the project ...

- Added GPL and LGPL licenses
- Added attribution for USART and Makefile
- Updated Makefiles

- 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
