avr 4311

We learn MCS51 single-chip microcomputer and AVR MCU, or PIC microcontroller, or MSP430 MCU, whether it feels that he can become an engineer? I'm here to say what I think.We learn these single-chip computer, the first study of theoretical knowledge, this is generally the theoretical knowledge of books, such as the introduction of the development of single-chip microcomputer, the application of single-chip microcomputer, the principle of single-chip mi

Question: give n ( Manhattan distance: We all know that the Manhattan distance between a (XA, Yb) and B (XB, Yb) in the two-dimensional coordinate system is ABS (xA-xB) + ABS (ya-Yb ); We can see that this distance is related to X and Y, but x and y

HDU 4311Test instructions: There are n points on the plane, one point (x, y) can only reach (X-1,y), (X+1,y), (×, y-1), (x, y+1) 4 points. Find a point from N points to minimize the sum of the distance from the other point to this point.Ideas:It can

This question has a certain skill, need to calculate the meaning of a point in the time complexity of nlog (N), N-1 points to the distance between the sum, here need to use such a technique, calculate the distance from X and Y separately. First,

Three working modes of at90can128 Timer/Counter 3:   Void initpwm (void)// Output compare and PWM output C for Timer/counter3{ Tccr3a = (0 (0 (1 (1 Tccr3b = (1 fast PWM mode (0   Ocr3a = 0x7ff; Ocr3c = 0xff; }   \\

Bit operationOne common task is to program the microcontroller MCU to enable or disable some bit of the IO register. Fortunately, standard C has good and applicable bit operation functions, without the help of assembly instructions or other

When we use 128 as the Ultrasonic Ranging module, there are always some gaps in the values, and the values are not stable enough. Check the program. The timer should start when the timer is started, rather than when the terminal is enabled. But

Note the following: Although the I/O port irrigation current can reach 20 mA (VCC = 5 V), 10 Ma (VCC = 3 V ), but must follow: Tqfp and MLF Encapsulation 1] The total number of all ports cannot exceed 400.2] fill current sum of port A0-A7, G2, C3-C7,

I used to want to use the compiler to write the MCU's C code, what the compiler did to help us. How the compiler allocates variables and code. So just idle to see what the compiler's installation path is. The ICCAVR compiler and Atmel Atmega64 are

Just getting started with Arduino, very good. Arduino ide I used version 0022 at the beginning, and its editor was really uncomfortable. I didn't prompt that auto-completion was not completed. Because I have been using eclipse for development, I am looking for a solution. My board is Arduino uno .. According to the official method, there is no result .... According to the arduino.tw method, there is no result... Finally, I finally found a way to solve the problem. The following describes the co

very rich and there is a huge amount of development resources for learning, for beginners like Xiao Zhu, It is very suitable as a starting point. A wide range of external devices (clock, relay switch, digital voice, etc) However, the 80C51 series provides a simple editor with relatively low performance (generally 12 MHz clock, enhanced performance up to 22 MHz, and each instruction requires an average of 12 clock cycles) weak I/O port capabilities, lack of effective software encryption,

Watching the Light Emitting Diode flash, I'm so happy. Success! For a newbie, this is the first time that we will never forget. ...... I have heard of avr in the csdn forum and downloaded programming and other things. When I searched for related information online, I found a

Recently, I intend to customize an Arduino board, change the Arduino's burn-write mechanism. Fortunately, bootloader are active code, say dry, before rewriting of course to try this source can compile, but to the bootloader directory is dazed .... Actually use is makefile, but as a program ape of course can't retreat ...1. Find bootloader Source codeBootloader source code are in the \arduino-1.6.9\hardware\arduino\avr\bootloaders folder, different mic
