Build status

---

• Clone repository
• Generate project files and build
• Force gcc compiler only

---

Clone repository

git clone https://github.com/mrsinho/bmp280_driver.git
cd bmp280_driver

---

Generate project files and build

mkdir build
cd build

If you have an environment variable named PICO_SDK_PATH which points to a Raspberry Pi Pico SDK root directory, do:

cmake -G"your-generator" -DBMP280_DRIVER_BUILD_EXAMPLE=ON ..
cmake --build .

Otherwise build the library by defining the PICO_SDK_PATH variable directly from the command line:

cmake -DPICO_SDK_PATH="your-pico-sdk-path" -G"your-generator" -DBMP280_DRIVER_BUILD_EXAMPLE=ON ..
cmake --build .

You can find the example source code at example/src/example.c The binary UF2 file is located at build/

Force gcc compiler only

If you don't want to use the C++ features and stick to the arm gcc compiler only, set ON the BMP280_DRIVER_FORCE_C_COMPILER variable. The command shown below will run successfully only if the line cointaining new_delete.cpp is deleted or commented out from pico-sdk-directory/src/rp2_common/pico_standard_link/CMakeLists.txt. There's a fork of the pico-sdk which is already set up for that purpose. Link: https://github.com/mrsinho/pico-sdk-c

cmake -DPICO_SDK_PATH="your-pico-sdk-path" -G"your-generator" -DBMP280_DRIVER_BUILD_EXAMPLE=ON -DBMP280_DRIVER_FORCE_C_COMPILER=ON ..
cmake --build .
