HSE_VALUE macro

Adjust the value of External High Speed oscillator (HSE) used in your application. This value is used by the RCC HAL module to compute the system frequency (when HSE is used as system clock source, directly or through the PLL). Value of the External oscillator in Hz

Syntax

from stm32f4xx_hal_conf.h:89
