Blink on STM32L031K6T6

[ITstreet1]

The regular Blink sketch on STM32L031K6T6 eats 65% of memory. The basic OLED example with the Adafruit lib can't compile. It turns out that 32KB STM32 MCUs are not usable in the Arduino world. Let's say I want to use OLED and SX1276. On ATmega32p, this is not a problem.

Is there a way to make Arduino IDE use waaaaaay less memory for the STM32 MCUs?
