HK32F030M PWM
航顺的库。。目前是 HK32F030Mxx_ExampleV1.0.5
PWM部分的demo还没做好，这里可以参照STM32F030的搞进去
这里输出 125K 定时器 就是 8us了

TIM2 Configuration: Encoder mode1:
In this example TIM2 input clock (TIM2CLK) is set to APB1 clock (PCLK1).
TIM2CLK = PCLK1
PCLK1 = HCLK
=> TIM2CLK = HCLK = SystemCoreClock
To get TIM2 counter clock at 32 MHz, the prescaler is computed as follows:
Prescaler = (TIM2CLK / TIM2 counter clock) - 1
Prescaler = ((SystemCoreClock) /32 MHz) - 1
TIM2 is configured to interface with an encoder:
- The encoder mode is encoder mode1: Counter counts up/down on TI2 rising edge
depending on TI1 level
- The Autoreload value is set to 10, so the encoder round is 10 TIM counter clock.
Note:
SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f0xx.c file.
Each time the core clock (HCLK) changes, user had to call SystemCoreClockUpdate()
function to update SystemCoreClock variable value. Otherwise, any configuration
based on this variable will be incorrect.
