The pa.8 pin of the STM32 has a multiplexing function-clock output (MCO), which enables the STM32 internal clock to be output through pa.8. Operation Flow: 1), set pa.8 to multiplex push-pull mode. Gpio_initstructure.gpio_pin = Gpio_pin_8; Gpio_initstructure.gpio_speed = Gpio_speed_50mhz; Gpio_initstructure.gpio_mode = gpio_mode_af_pp; Gpio_init (Gpioa, gpio_initstructure); 2), select the output

The PLL is an abbreviation for the phase-locked Loop, and the Chinese meaning is a phase-locked loop. The PLL is essentially a closed-loop feedback control system that allows the PLL output to maintain a fixed phase relationship with a reference signal. The PLL is typically composed of a phase detector, a charge amplifier (Charge Pump), a low-pass filter, a voltage-controlled oscillator (electrical), and some form of output converter. To make the PLL's output frequency a multiple of the referenc

1. Enter the CCS environment, load the existing project, load the generated. Out file, and find the code to view the code execution cycle. 1.Figure 1 1. Select enable clock in profiler of the CCS menu ,.Figure 2 2. select the clock setup sub-menu under the profiler menu, and enter your DSP clock cycle in instruction cycle. The unit is nanoseconds. For example, 24

During the hardware design of the product, EMI should be considered at the beginning of the design to reduce the financial and human resources required for subsequent rectification. This paper uses the clock signal as an example to design EMI to reduce radiation interference. (1) Schematic Design 1. the power supply of the clock chip is separated from other power sources by magnetic beads. The decoupli

The clock speed not only can update the system clock from the NTP server, but it can also calculate the clock frequency and manage the system time accordingly. Many people who want to keep an accurate computer clock use network time Protocol (NTP) to set their clocks at the same times as the atomic clocks. NTP is a wa

An error appears when the ISE is routing the layout.There are two possible reasons for the "Clock_dedicated_route" error:1. There is a clock you do not put to the global clock or local clock pin, the layout can not be used as a clock to allocate resources.2. Is you want to output a

The electronic clock of QT is an old demo, but the display of lcdnumber is very old (the first display effect ), at first glance, we can see that the example is extracted from the QT help document and there is no new idea. Beautify the system clock, put aside the inherent controls, and make the DIY effect eye-catching. Knowing the details determines the UI's success or failure. This is what I have been p

Program Blink of an eye a year again, oneself again old one year old, depressed ah. Take advantage of some Zhong Cai New year, and quickly send a few more articles to add something to the past year. The program is found from the Internet and is a simple clock display program. Code Features:The clock code provides a variety of interfaces that can be set in HTML files, changing the colorful

For the OK6410 clock part, we can find the relevant system controller in the system controller from the initi6410 manual: Power indicates Power-on. After the Power-on is stable, the 12 M crystal oscillator is also stable after the vibration starts. Then, the CPU can obtain a relatively stable clock frequency (12 M). If you want to change the frequency of the crystal oscillator, we will give him a locktime

The following figure shows the system clock schematic of 6410: Of Formula for determining the clock frequency of 6410: fout= Mdiv * FIN/(pdiv * 2 ^ sdiv) The values (mdiv, pdiv, sdiv) are in apll_con and mpll_con. Fin is the input clock of our system, and ok6410 is 12 MHz. To get the final output clock, you must set th

Question .. Calculate the angle between the hour hand and the minute hand at any time, and the result is between 0 ° and 180 °. The sscanf () function is used again here, which is really convenient. Idea: we calculate the angle between the hour hand and the minute hand, and then decrease the value. If the ANS result is greater than 180, ANS = 360-ans. Clockhands The medieval interest in mechanical contrivances is well formed strated by the development of the mechanical
