A custom variant for stm32Duino for the stm32F107VCT processor, specifically tailored for the 'NICE' (Nissan Inverter Controller par Excellence) PCB.

1. Navigate to your stm32Duino variants directory. It should be something like:

.../variants/STM32F1xx

2. Create a folder named F107VC(NICE) within this directory.

3. Download the following files and place them into the F107VC(NICE) folder:

   • boards_entry.txt
   • CMakeLists.txt
   • generic_clock.c
   • ldscript.ld
   • PeripheralPins.c
   • PinNamesVar.h
   • variant_generic.cpp
   • variant_generic.h

4. Before proceeding, it's recommended to backup your original boards.txt located at:

.../packages/STMicroelectronics/hardware/stm32/2.4.0

5. Copy the provided boards.txt and overwrite the boards.txt in the directory mentioned above.

• This variant is set up for an 8MHz crystal, and the processor runs at 72MHz. This configuration is essentially the same as a BluePill in this regard.
• Currently, compatibility is maintained up to core version 2.4.0.
