For a frame of 11-bit data 0.000104166666666667x11 = 0.00114583333333334 The data can be transmitted within one second. 1/0.00114583333333334 = 872.727272727268 872.727272727268 frames of data. Of course, this is only calculated in numbers, but there are actually many invisible latency factors. Experiment 10: Serial Port receiving module In terms of seria

. When other threads access an object, the calling thread will wait. The pulse signal is used to notify the waiting thread of changes to the object state. Pulse (), PulseAll () sends signals to one or more waiting threads. This signal indicates that the status of the waiting thread lock object has changed, and the lock owner is ready to release the lock. Wait for the thread to be placed in the ready queue o

take a specific implementation-8051 built-in UART for analysis. The 8051 built-in UART can work in four modes through software programming: Mode 0, Mode 1, Mode 2, and mode 3. Here, we will briefly analyze the asynchronous communication process using the commonly used 1-8 bit UART with variable baud rate. The frame size of Mode 1 is 10 bits: one start bit (0) + eight data bits (minimum valid bits first) + one stop bit (1), at the receiver, the stop bit is sent to the serial port's control regis

Each metadata block is a variable-length ENHMETARECORD structure. The structure is as follows. typedef struct tagENHMETARECORD { DWORD iType; DWORD nSize; DWORD dParm[1];} ENHMETARECORD, *PENHME

combinations based on the phase relationship between transformer and sub-winding force. In order to distinguish different joining groups, the long needle of the clock is represented as the line EMR at the high voltage side,The short needle of the clock is represented as the line EMR at the low voltage side.

matching Register matches Tc (the timer value), the output flat of the PWM is pulled to a high level. You can set the MR3 value to the PWM period, and set the timer to reset when matching the MR3 value. After the timer is reset, the TC value is cleared. After the timer is reset, the high levels of all PWM outputs are cleared. If it is set to PWM output, the settings in the external matching register EMR no longer work. Ii. Example of timer Initia

Basic commands The following basic AT commands allow you to call, select a dialing method (audio or pulse), control the speaker volume, and perform other basic modem operations. Important: you must use the AT command in the "command" mode of the communication softwa

Distributed Optical Fiber Temperature Measuring System Based on backward scattering principles can be divided into three types: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering Distributed Optical Fiber Temperature Measurement System Based on Raman scattering. Its sensing princi

N LCD start control bit (ENB) When ENB is set to 0, all LCD pins are used as general IO ports; When ENB is set to 1, the LCD controller is enabled.

They are the default counter values respectively. N-row front null pixel cloc

TVS main parameters of diodes--reprintThe best way to deal with the damage to the device by instantaneous pulses is to draw the instantaneous current from the sensitive device. The TVs diode is connected in parallel with the protected line on the circuit board, and when the instantaneous voltage exceeds the normal operating voltage of the circuit, the TVs diode has an avalanche that provides an ultra-low resistance path to the instantaneous current, which results in instantaneous current being i

the server side works. pulse pulse is more like a short message, is also sent on the connection. The most important feature of a pulse is that it is asynchronous. The sender is not required to wait for the receiver to answer, and can proceed directly. However, this kind of asynchrony also brings a limitation to pulses.

time front of the time point is aligned with the front of the reflected wave, the number displayed on the digital monitor is the fault point distance.3. How to determine the nature of fault points1) when the line is normal, there is no reflection.2) when the line is disconnected or the contact is poor, the reflection pulse is the same as the emission pulse.3) the insulation is reduced when the line is shor
