Arduino for STM32

Simply add a hal_conf_extra.h file with:

#define HAL_OPAMP_MODULE_ENABLED

For ref:

That's only one step in the whole process.

I used CubeMX to generate the code for the main and the msp. Then ...

I was able to make it work!

In the Arduino make a new tap (create a file named "hal_conf_extra.h") and paste the following code:
#if !defined(HAL_OPAMP_MODULE_DISABLED)
#define HAL_OPAMP_MODULE_ENABLED
#else
#undef HAL_OPAMP_MODULE_ENABLED
#endif

The main Arduino code:
OPAMP_HandleTypeDef ...

Hi guys,

Can someone explain how to enable the opamp in the G4 board?

I found this wiki, and it looks like I need to create a file "variant.h" to enable the OPAMP peripheral. I really don't know where to start here. I know how to do it using CubeMX but I have never done it in Arduino.
