Hclk clock frequency
WebMar 14, 2024 · 1. RCC_GetSYSCLKSource () gets the source of the system clock source. 2. STM32F103R8T6 chip is used this time. 3. My board has no external crystal oscillator, but the system clock frequency is obtained by multiplying the internal high-speed oscillator (HSI), so the maximum frequency can only be doubled to 64MHZ. Webrequirements (VDD ) versus the system clock frequency and Flash latency versus the system clock frequency. Three different clock sources can be used to drive the system …

We are getting closer. Let’s say, our system clock is 180000000 Hz (STM32F429 Discovery). If we want to make a simple 1us delay, then we have to count 180 ticks to get this. If one while loop takes 4 cycles, then we have to divide our counter by 4.
WebThe maximum frequency of hclk is 168MHz, of pclk1 is 42MHz, and of pclk2 is 84MHz. Be sure not to set frequencies above these values. ... To wake from this sleep state requires a real-time-clock event, or an external interrupt on X1 (PA0=WKUP) or X18 (PC13=TAMP1). Upon waking the system undergoes a hard reset.
