is changed, and a redo is generated and output to the redo log file. The previous mechanism has the following problems: if another session needs to search for old data in the undo block, but the undo block has been refreshed and output to the disk, it needs to be retrieved from the disk, there is a certain I/O overhead. At the same time, after private redo is introduced, the redo and undo that describe a data change cannot refresh the output to the redo log file together. Therefore, oracle intr

How to generate an analog outputFrom a in-built PWM of Atmega 32AVR Microcontrloller?You need a resistor, a capacitor and an opamp.Opamp is isn't really necessary when you are driving a mosfets, but would make life a bit easier.Just be aware, the this DAC would be quite noisy or/and slow.The bigger cap/resistor values, quiter and slower the output.Another thing to being aware is so you better use 16bit PWM, as 8 bit PWM would give you only discrete values-That could is enough or too coarse, depe

Original Address-Https://www.arduino.cc/en/Tutorial/DimmerLight dimmerThis example shows how to send data from a PC to the Arduino/genuino Development Board to control the brightness of an LED. The data is sent in separate bytes, with a range of 0 to 255 for each number. The program reads these bytes and uses them to set the brightness of the LEDs.Hardware requirementsArduino or Genuino Development Board Led 220 Ohm ResistorSoftware RequirementsProces

Intel Galileo Gen 2 Machine Road In fact, the first time I heard to make this board when I was refused, because, you can not let me, I immediately go to engage, the first I want to try, because I do not want to put some special stunt up, board "crashed" a bit, very good, very good, so that people will scold me, there is no such board, To prove that the Intel board is fake. Later I also confirmed that they are really good, I used about a day, I feel good, and then I was engaged in the ti

0x00 What is ArduinoArduino is actually a development board, the microcontroller and the necessary components integrated into a circuit board, expand the perfect interface and pins, you can connect a variety of sensors, complete the design of your mind, you can also understand it as an electronic building block, because it does not need to weld, Also does not need the advanced radio knowledge, only needs the programming foundation and the basic circuit knowledge.Arduino does not need to know the

look at it again. (1) If no index is found on the ID column (1) query the data dictionary such as SEG $, find the T_GYJ table field header (2) read the Extent Map from the field header and start full scanning (3) find the first row that meets the condition, modify it (4), find the remaining row in the same block, construct a CR block, and continue searching in the CR block, if the row that meets the condition is found, modify it in the Xcur block. (2) If the ID column has an index and the versi

in the CR block. If the row that meets the condition is found, modify it in the Xcur block.(2) If the ID column has an index and the version is not 11GR1 (10G, 11GR2), no CR block needs to be constructed.(3) No matter whether the ID column has an index or not, a CR block must be constructed in 11GR1.(4) If the NAME column has an index, add the index maintenance steps:(1) first Delete the original value to be modified in the original index Block(2) Insert the new value(5) perform the following s

Two days ago, I saw an article About the technical documentation "All About Oracle's In-Memory Undo" on the relevant Internet. This article mainly discusses Oracle In-Memory Undo (IMU, we have talked about it in the past few years. Most of them are based on speculation. This is the first detail. Oracle has applied for a patent for the IMU feature launched at 10 Gb ). As one of the most important components

Recently set a graduation design topic, probably to do slam direction, just Google recently open source of his indoor slam library cartographer, I took to use the laboratory robot tried, the overall effect is very good.

developed in Arduino without worrying about boring compilation and machine code, because the Arduino IDE has a Processing/Wiring development environment similar to Java and C language. Environment installation and setup is also very convenient, you can download the installation package from the http://www.arduino.cc, installation.

the data structure of the log messages. For example, GPS messages are used to record log data for GPS sensors. It can store this data very efficiently, and it also provides APIs for other libraries for log callbacks and downloads.The log data structure is custom, and its structure allows you to view the FMT messages for the log files. The format in which the FMT message should be stored in other data.Related Routines Libraries/dataflash/examples/dataflash_test/dataflash_test.pde. The storage st
