Dear all,I am using STM32F103RBT6. I am wondering if I can leave folating the Pin for OSC32_IN/OUT because I didn't need them for my application.I want also know, how can I do the shield of the MCU STM32?Best regardsHafedh

Hello,I didn't find in the datasheet, that MCU STM32F103 have an internal pull-up/pull_down.In this case. Should I make all unused I/O in pull-up or pull-down state?Thank you for your supportBest regardsHafedh
