Can't compile code with the Servo library with a Blackpill (STM32F401CCU6)

I wrote some code to test a ESC I bought for my sumo robot. To control the motors with an Arduino, I would use the writeMicroseconds() function from the Servo library with a value ranging from 1000 to 2000 (with 1500 being neutral) as a parameter.

Now, instead of an Arduino nano, I’m using a Blackpill (STM32F401CCU6). And when I try to compile the code, I get the following error:

In file included from src/main.cpp:3:
.pio/libdeps/blackpill_f401cc/Servo/src/Servo.h:77:2: error: #error "This library only supports boards with an AVR, SAM, SAMD, NRF52 or STM32F4 processor."
   77 | #error "This library only supports boards with an AVR, SAM, SAMD, NRF52 or STM32F4 processor."
      |  ^~~~~

I don’t understand why it doesn’t work because the error says that the SMT32F4 platform is supported.
I’ve seen that it is possible to generate the signal I want with different methods, but I want to make this one work because of its simplicity.

I’m sort of new to development on microcrontrollers, so if this question seems naive, it’s because it is.

Full platformio.ini?

No. This line should be removed and the .pio directory should be deleted for a clean rebuild.

The Arduino core already has the correct Servo library built in. Core built-in libraries need not be declared. You’re forcing the wrong Servo library into the build.
