・・・が、arduinoは認識はしてくれないようです。
調べていくうちに、STM32F103C8をArduinoで扱う方法は少なくとも２種類あるようです。
【その１】stm32duinoで、追加のボードマネージャのパスを設定した後、ボードマネージャで「STM32 Cores by STMicroelectronics」を追加する方法。
（前回の記事の方法）
【その２】ボードマネージャで「Arduino SAM Boards (32-bits ARM Cortex-M3) bu Arduino」をインストールした後、~/Arduino/hardware の下にライブラリを追加する方法。（Arduino_STM32）
