2024-05-27(6): Cross Development, Toolchain Installation

Cross Development

• Cross Development

• CMake: Cross Build

• Cross Toolchain Setup

Exercise: Install Cross Toolchain

• Setup cross toolchain as in Cross Toolchain Setup

• Download CMake toolchain file as in Cross Toolchain Setup

• Build the project from the last exercise, Exercise: Reading A Sensor (Driven By Tests)

C++ Intro: Livecoding Session

See https://github.com/jfasch/FH-STECE2022/tree/main/livecoding/sensor-oo-c for code.

• Morphing Exercise: Reading A Sensor (Driven By Tests) into something object-oriented, but still C

• Introduce exception handling; this is done to overcome the weird function signature of sensor_get_temperature().

  • Causing exceptions (throw): https://github.com/jfasch/FH-STECE2022/blob/main/livecoding/sensor-oo-c/lib/sensor.cpp

  • Reacting upon exceptions (try, and catch)

    • Production code: https://github.com/jfasch/FH-STECE2022/blob/main/livecoding/sensor-oo-c/bin/read-sensor.cpp

    • Test code (attention, the logic seems somehow inverted): https://github.com/jfasch/FH-STECE2022/blob/main/livecoding/sensor-oo-c/tests/suite-sensor.cpp
