STM32L051R6T6 .IOC file

Hello,

I am beginner with STM32.
I have some radiosonde boards with an STM32L051R6T6. I use STM32CUBE IDE V2.0.0
When I start a project, select the appropriate MCU, there is no Core directory and no ".IOC" file.
So, it is impossible to access to the GPIOs.
I've tried some ways to do that and allways unseccessfull.

Please, have you an idea ?


Notice
I use also an STM32F103C8T6 board.  I've create my own GPIO lib, my own I2C lib,  and I can compile, flash, debug and run my program.

Thank you and sorry for my english

Use standalone STM32CubeMX to create new projects. Projects can't be created in STM32CubeIDE anymore.

Hello,

"Projects can't be created in STM32CubeIDE anymore."

But STM32CubeIDE can create an STM32F103C8T6 project.

I'll see how to install STM32CubeMX.

Thank you

Not anymore starting from CubeIDE 2.0.0. CubeIDE and CubeMx have been separated.

IDE Version 2.0.0 - why remove MX ?
