Introduction to input CaptureThe input capture mode can be used to measure the pulse width or measurement frequency. STM32 timers, in addition to TIM6 and TIM7, have input capture capabilities for other timers.STM32 input capture, simply by detecting the edge signal on the TIMX_CHX, when the edge signal jumps (such as rising edge/falling edge), the value of the moment timer (timx_cnt) stored in the corresponding channel capture/comparison register (TIMX_CCRX) inside, Complete one capture.To use
CPU, do not only consider the clock speed. The CPU clock speed of the computer does not represent everything. For example, the clock speed of 630 is 3.0, but it is not 820 (clock speed 2.8) expensive, why is it that the CPU is effective? Think about other things and you will get twice the result with half the effort. At the same time, you must be careful about JavaScript deception. Please be careful when using low-price CPU but same-frequency CPU.

1. Function and principle
The basic timers TIM6 and TIM7 each contain a 16-bit automatic load counter, which is driven by the respective programmable prescaler. They can provide a time base as a general-purpose timer, especially for a digital-to-analog converter (DAC). In fact, they connect directly to the DAC inside the chip and drive the DAC directly through the trigger output. These 2 timers are independent of each other and do not share any resources.
The graph shows that its clock source c

These aspects are intertwined throughout the entire software development process.

After working for a while and using Java in depth, let me talk about my feelings.
My own profession may have to scold some people. I honestly say that I am outsourcing Japan. Doing this job doesn't mean how fond I am of Japan, but it is hard to find a job now, in addition, we also export data to Japan and do not import data from Japan. Our company has two outsourcing departments, my department is mainly eng

Power Supply and reset
Da Vinci DMSoC has two power domains: The Always On domain and the DSP domain. The Always On field is powered by the cvdd arm core and provides power to ARM, bus, SCR, and all peripherals except VICP. The DSP power field is powered by the CVDDDSP core, provide power to DSP and VICP.

Just looked at the STM32 General Timer tutorial, in fact, and 51 of the timer use almost. Just because the 32 clock is more complex and can manipulate more registers, it can be more complex to write.General steps to use general timer interrupts:1. Enable Timer clockThis needs to look at the clock tree, so that the corresponding clock will be good. I'm using TIM3 here, so I can APB1 the clock.2. Set the frequency divider and reload value of the timerTimer Interrupt Time: Tout = (arr+1)/[tclk/(
tim5_cnt value is recorded at this time. In this way, the difference between the front and back two tim5_cnt is the pulse width of the high level, while the counting frequency of the TIM5 is known, so that the accurate time of the high-level pulse width can be calculated.Enter the configuration steps for the capture:1) Turn on the TIM5 clock and the Gpioa clock and configure P A0 as the drop-down input.To use TIM5, we must first turn on the TIM5 clock. Here we also configure P A0 as the drop-do

(); // release the context of the server object, that is, close the process.
ServerContext is essentially a process on the GIS server, and it is also the starting point of Server programming. Therefore, the CreateServerContext command is created on the server, instead of the NEW keyword. We access the server object nbserver through this process. Our work is also completed in this process.
Since it is programmed in a process, the keyword used to create an object in this process is not NEW, but t
