High speed clock hse
WebBy default, the HSI, or high-speed internal, clock is the clock used as the system clock. However, we can change this to either the HSE clock or the PLL clock. In comparison to the HSI clock, the HSE clock offers an advantage in that it is more accurate than the HSI clock, which relies on RC circuitry to generate the clock signal. WebNov 2, 2024 · This presentation is made as a part of our udemy course on STM32 MCUs and peripherals. The ppt covers STM32 Reset and Clock Control unit of the STM32 , different types of clock sources such as HSE (High Speed External crystal), HSI (Internal High Speed RC ), PLL concepts,HSI calibration , HCLK,PLCKx and others.
