Recommendation 51: Types with disposable fields or types that own native resources should be disposableIn recommendation 50, we divide the types in C # into ordinary types and non-trivial types that inherit the IDisposable interface. Non-trivial types, in addition to the types that contain those managed resources, themselves contain a field of a non-trivial type.In the standard dispose mode, we give an example of a non-trivial type: an Anotherresource

51 Single Chip Microcomputer pin ale/prog/psen/EA/VPP Reprinted from:Http://www.how138.com/news.asp? Id = 576 Four control pins of 51 single-chip microcomputer, one of which is the reset pin (RST/VPD)RST is the reset pin. When the RST input end maintains two or more machine cycles, It is reset. Ale/prog is the allowable output end of the address lock memory. It is used to lock 8-bit address signals whe
that you are reading the article, you must be able to experience it. It is also a blessing to take a wonderful view of the exotic scenery.Third, develop a "sister-in-the-girl" planFor this matter, it varies from person to person. Generally speaking, however, the steps are generally the same. As space is limited, it does not begin to tell the story:① manufacturing encounters, surprises constantly②, getting into the theme③ at first sight, sister successThe small part may not be all right, but it
Burst a think, my technical articles reproduced so much, there is no personal life or workplace articles, the following copy of a university to write QQ log (in 2013-6-23 16:51), will continue to update, PS: Writing rotten to the slag.The recent graduation season found that the space dynamic inside the log more and more, the twilight (do not know this idiom with the right place) only to find that they have been a long time without writing a log, the U
Hi, Big Ben! PMP September Certification Exam results, finally came out!In the first time, we received the students of the N more than the results of the class group in a lively atmosphere, in this wish everyone successfully passed the PMP certification exam!!"If there is something to be done, the Hyakuji of the Qin Dynasty will be the most, and the days will not be negative; hardships, 3,000 Yue Jia can swallow Wu."

Wrote a half-day off the line ...Not written on the definition ...What is interrupt interrupt means that the CPU in the process of executing the current program, because of some random peripheral request or internal CPU abnormal events, so that the CPU suspends the executing program and go to execute the corresponding service handler; When the service handler finishes running, the CPU returns to the halt and resumes execution of the original program. 51
Have to say, 51 after the rhythm of an instant rise, every day to listen more and more quickly, homework is more and more, on this one weeks time, vaguely feel the sense of overtime rhythm, every night to sleep 1 o'clock, the latest day is 3 o'clock sleep, the next day at 7 o'clock wake up feeling legs are not stable, no force ah, It seems that I have adjusted Kazakhstan's own state of rest, good, spit trough or say a little bit of their feelings and

This is an example of ym12232b LCD driver using 51 single-chip microcomputer. My level is limited for your reference only. In this example, 51 single-chip microcomputer is used to control the ym12232b LCD. The "subject" and "" characters are displayed in the main and secondary Windows respectively. Ym12232b has a total of 18 pins, as shown in the following figure: The display format of ym12232b is as follo
1. The data zone has a small space, so only variables that are frequently used or require high computing speed are placed in the Data zone, such as the Count value in the for loop. 2. It is best to place local variables in the Data zone. Because the space of local variables can be overwritten (the space of local variables of a function is released after exiting the function, and is overwritten by the local variables of other functions), the memory usage can be improved. Except for static local v
1. After you insert 51 Single-Chip Microcomputer usb to the serial port, run the # lsusb command to check the USB device. The pl2303 driver has been integrated in Ubuntu and does not need to be installed. 2. Use # dmesg | grep usb to check its installation. ttyUSB0 is connected here. You can also use # ls-l/dev/ttyUSB * To find the serial port 3. install minicom: # sudo apt-get install minicom 4. Configure minicom: # sudo minicom-s 5. On the confi
I learned some basic information about 51 Single-Chip Microcomputer before the winter vacation, but it has been suspended for a long time, I feel that my bad habits have not been in the optimal state for a long period of time. My brain seems to be Rusty. From today on, I have created a blog every day, not for others, recording my own life, and recording my own progress. Practice is king. Come on, cool !!!! 1. Use a matrix to control the source code of
In the previous article, we mentioned that we should call the encapsulated DS18B20 in a specific project to obtain the current temperature. Let's take a look at how to call the completed gettemp function in the following example to measure the temperature. First, our design includes the following: 1. Use the DS18B20 digital temperature sensor to obtain the current temperature value. 2. display the current temperature value on the digital tube. 3. Send the temperature value to the host computer u
