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_peripheral

Unsigned int32. Timer register address base

Returns

Unsigned int32. Timer base frequency
