Start of the AVR 2017128a Timer

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

Introduction to driver capabilities of avr I/O

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,

Write and install the Arduino program on Eclipse Helios

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,

How to Use the ATmega128 timer 1

We haven't gotten over the AVR for a long time. This time, we are going to improve the school's low-level robot driver. First, we will do a few necessary small experiments. Both AVR and ucoⅱ are good things ~~, The compact and fast running speed reminds people of the previous dual-wheeled car made by a foreigner using AVR as the CPU. This is really exciting .. /

A new type of key scanning program

However, I have been on the internet for a long time, have seen a lot of source program, did not find the trace of the key handling methods, so I will share him out, and the vast number of colleagues to encourage each other. I strongly believe that this key handling method is convenient and efficient, you can migrate to any kind of embedded processor above, because C language powerful portability.At the same time, the use of a number of layered ideas, in the microcontroller is also quite useful,
