In STM32, there are five clock sources for HSI, HSE, LSI, LSE, PLL.In fact, four clock sources, as shown (gray-blue), PLL is a PLL clock that is multiplied by a phase-locked loop circuit. ①, HSI is a high-speed internal clock, RC oscillator, frequency of 8MHz.　　②, HSE is a high-speed external clock, can be connected to the quartz/ceramic resonator, or external clock source, frequency range of 4mhz~16mhz.　　③

The vertical distribution rate will be decreased slightly even if the de-discrimination algorithm is used.1.2 Color Space 1.2.1 different color spaces are used differently For a black-and-white image, we use brightness (or grayscale) to indicate its brightness or darkness, generally, we use 8-bit, 10-bit, or even 16-bit non-conforming Integers to represent the gray scale of a pixel.

The original Article portal has five clock sources in stm32: Hsi, HSE, LSI, LSE, and PLL. There are actually four clock sources, as shown in (gray-blue). The PLL is generated by the frequency doubling of the PLL circuit.① HSI is a high-speed internal clock, RC oscillator, with a frequency of 8 MHz. ② HSE is a high-speed external clock, which can be connected to a Z/Ceramic Resonator or an external clock sou

The stm32 chip manual shows clearly that there are four clock sources: 1. HSI (Internal High-Speed clock 8 MHz) provides a clock source that supports BIT system clock 2. HSE (external high-speed clock) provides system clock and RTC clock source 3. LSE (low-speed external clock 32.768 kHz) can provide a clock source for rtc 4. LSI (low-speed internal clock) can provide the clock source for the independent watchdog First, let's analyze the database fu

return a table.But sometimes we want to use the Table1 field as a parameter, to pass in the function to calculate, like:SELECT * FROM table1 join MyFunction (ID) on 1=1This is going to go wrong. This time we can use apply to achieve. For example:SELECT * FROM table1 cross apply MyFunction (ID) on 1=1Simply put, apply allows us to pass the data of each row of the preceding result set as an argument to the following expression, which can be either a table-valued function or a select result set.Ac
