RealPlayer This veteran player has been 20 years of history, the player since the release of the first edition in 1995, has been favored by many users, but in previous years RealPlayer did not appear in front of the public, And in the recent RealPlayer announced the exit of the next generation of players--realplayer HD, the player on the original basis of the upgrade, many users must have installed the player in the first time, but some users want to adjust the audio balance in the player parame

These two days to the external interrupt and the ADC looked down, the personal feeling that the external interruption is not difficult, it is not written down, after all, it is a waste of time to write. ADC is more complex, and if you want to make it possible to use the ADC completely freely, it has to go through many practices. Because I have learned the library

Embedded systems occupy an important position in the field of micro-control (temperature, humidity, pressure detection, four-axis aircraft), which are implemented by microprocessor CPUs (such as STM32) and sensors and controllers, and connect them so that they can communicate with each other properly. is the module to be sued in this section, ADC Analog-to-digital conversion peripherals. Let's start with the simplest experiment and learn more about th

ADC conversion is the input analog signal volume, the microcontroller converted to digital volume. Reading the number must wait for the conversion to complete, the completion of a channel reading is called the sampling period. Sampling period generally = conversion time + read time. The conversion time = sampling time + 12.5 clock cycles. The sampling time is the time you tell the STM32 sampling analog through the register, the longer the setting the

On the basis of the previous note, complete a simple ADC sampling experiment.The first step: preparation of knowledge1, first look at the Bb_black ADC pin position. Is the distribution of the analog input ports of the bb_black.There are three important messages to note on this chart:(1) Number of analog input ports: ARM chip A total of 8 ADC channels, the Bb_blac

Before learning a number of modes of electricity, A/D conversion of the knowledge, also Baidu a lot of information is difficult to understand. Forget, first self-righteous, and so on after the study of specialized courses and then again. (You must learn to go home in winter vacation.) Well, that's what it's all about. Reading so much information, the sense of A/D conversion is the voltage (or other analog: such as pressure, image, etc.) into the digital, d/A is the reverse, and the

Now the software, radio, digital Image acquisition requires a high-speed A/d sampling to ensure the effectiveness and accuracy, the general measurement and control system also hopes to have a breakthrough in precision, the tide of human digitalization to promote A/D converter constant change, and A/D converter is the pioneer of digital human realization. A/D converter has been developed for more than more than 30 years and has undergone several technological innovations, ranging from parallel, s

Many friends of the PC are installed every day beautiful bar, in every day in the sound can be set in the PC audio equalizer to make music more in line with their taste, using this method than the online recommended music mode is better to listen to more, but many small partners do not know how to set, the following small series to everyone detailed introduction to set the method, Hope to be able to help everyone. How to set the

In equalizer, server, as an independent process, manages and schedules the entire parallel rendering system. Its main tasks include loading configuration scripts, listening, and establishing connections with nodes, responds to messages from other nodes. Since EQ: Server is a subclass of EQ: node, it is similar to the latter in many aspects. 1. Load the configuration scriptIn the initialization phase of EQ: Server, EQ: SERVER: loader and its multiple o

Today, I browsed it online and found that equalizer 0.4 has been released. It is strange that I didn't see any related information on the OpenGL official website. According to the eile description, in addition to adding support for the body rendering method, version 0.4 focuses mainly on simplifying interfaces to facilitate the rapid transplantation of graphic applications. However, the experience I have tried over the past two days is not easy to us

Test instructions: Give two equal length strings, 0 can become 1,? can become 0 and 1, can arbitrarily swap the position of any two characters in S, ask at least how many times to change from S to T.Analysis: First of all my ideas, I see this should be greedy, first of all, if the first Judge S can become T, calculate T in 1 and s in 1.And then figure out how much more t than S 1, and then first consider putting? Become 1 is the best, if not enough can only turn 0 into 1, must not be put? become
