I'm working on a project using a STM32H747XIHx dual core processor.  I believe I have the latest STM32CubeIDE and STM32CubeMX tools.  How do I configure CubeMX to generate GPIO initialization code for my I/O signals?
I am developing a numeric keypad and I need to have a backspace key.I'm using Flex buttons and I want the character specified by "U+232B" to show up on the button.How do I enter this in a "Text Visual Element".
