WebHCLK is then derived from SYSCLK, but by a prescaler of 1:1...1:512. However, this scheme can vary depending on the STM32 family and use different naming conventions. Depending on the specific family the MCU core is usually clocked by HCLK. Therefore, when we talk about the time to execute instructions, we talk about the HCLK clock … WebSep 19, 2014 · I got result, that while loop “while (variable–);” takes exactly 4 clock cycles. 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. エクセル cells range https://dreamsvacationtours.net

WebFCLK Frequency is the frequency at which Infinity Fabric Clock operates on. Infinity Fabric interconnect core components like CPU, RAM and others and is used for data and control transmission. FCLK Frequency is the frequency of data and control transmission between different components. Sample value of FCLK Frequency is 2500 MHz. 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.
