Recently used in the temperature and humidity sensor, AM2305 drive, single bus, on the power of at least 2S to read temperature and humidity, temperature accuracy is high, like DS18B20, data with the checksum, will not appear ds18b20, and the timing

Go has no exception mechanism like Java, it cannot throw an exception. Because designers think it's easy to confuse the code by mixing anomalies with control structures. The introduction of exception treatment: Defer,panic,recover; Simple

JS bubble and closure case analysis Background: Today, I found Baidu aware of an interesting JS problem on the webpage. The question of the questioner is actually quite simple. I should be able to implement front-end development technology. The

This is a creation in Article, where the information may have evolved or changed. Like other programming languages, the go language has its own process control structure, such as conditional branching, looping statements, and so on. In addition,

The counter works like this: it has an input frequency that is 1193180HZ on the PC. At each clock cycle (CLK cycles), the counter value is reduced by 1, and when it is reduced to 0 o'clock, an output is triggered. Since the counter is 16-bit, the

First, the general introduction:Stepping motor is an open-loop control element stepping electric part which transforms electric pulse signal into angular displacement or line displacement. In the case of non-overloading, the speed of the motor, the
