Firmware of liquid He monitors, that monitor the level of He dewers. They are meant to be used in conjunction with Helium Management application.
In order to start developing/testing/flashing Firmware you will need:
- Microchip Studio
- A debugger for example Atmel Power debugger
- Levelmeter
Before first compiling the project in Microchip Studio the submodule of the avr-library needs to be initialized:
git submodule update --init
In order to generate a executable Firmware of a specific release, git tag will list all available releases and
git checkout --recurse-submodules vX.XXX
will load the release specified by vX.XXX (for example v1.221).
Build configurations are used to generate firmware binarys that are meant for the same device Type, but with varying Hardware, for example the display that is used. Build configuration names for Levelmeter have the following Format 'DisplayType'-'DisplayConfiguration' and can be set via the dropdown menu depicted in the screenshot below.
