STM32F HAL Library too large

Question

I just ran out of flash on my microcontroller project. How can I reduce the size of the HAL library or otherwise make it take less of a huge percentage of my project?

Answer 1

In addition to all of these great responses, I'd like to add that the HAL can be configured in stm32f3xx_hal_conf.h to disable unused modules.
