 * `TOOLCHAIN_PREFIX` - where toolchain is located, **default**: `/usr`
 * `TARGET_TRIPLET` - toolchain target triplet, **default**: `arm-none-eabi`
 * `STM32_CHIP` - STM32 device code, e.g. `STM32F407VG` or `STM32F103VG`
-* `STM32_FAMILY` - STM32 family (F0, F1, F4, etc.) currently, F0, F1, F2, F4, F7, H7, L0, L1 and L4 families are supported. **Note:** If `STM32_CHIP` variable is set, `STM32_FAMILY` is optional.

 To use the toolchain, you'll need to copy contents of the `cmake` folder into cmake's modules path, or use the `CMAKE_MODULE_PATH` variable.
