◆ timer_get_frequency()

uint32_t timer_get_frequency ( uint32_t  timer_peripheral)

Get Timer clock frequency (before prescaling) Only valid if using the internal clock for the timer.

Currently implemented for STM32F1x and STM32F405xx/407xx STM32F415xx/417xx. Not valid for STM32F42xxx and STM32F43xxx.

Parameters
[in]timer_peripheralUnsigned int32. Timer register address base
Returns
Unsigned int32. Timer base frequency
