Gitakichi Tokyo / Mbed 2 deprecated BME280_attitude

秋月電子通商のBME280温湿度気圧モジュールにて高度を測定しました。 ボードはSTM32L152REを使いました。 meas attitude by BME280 Module of Akiduki and STM32L152RE. http://akizukidenshi.com/catalog/g/gK-09421/ http://www.st.com/content/st_com/ja/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-nucleo/nucleo-l152re.html
