To convert one into the other, you must reverse the byte/nibble positions and then reverse all bit positions of each byte/nibble or write it as one binary string and reverse/mirror it. Example: 0xCB 34 01 02 0x20 10 43 BC after nibble reverse 0x40 80 2C D3 after bit reverse of ...
I2C总线的Arduino库函数 I2C即Inter-Integrated Circuit串行总线的缩写,是PHILIPS公司推出的芯片间串行传输总线。它以1根串行数据线(SDA)和1根串行时钟线(SCL)实现了双工的同步数据传输。具有接口线少,控制方式简化,器件封装形式小,通信速率较高等优点。在主
Working with Strings in Arduino is different from working with Strings in Processing or openFrameworks because the Arduino language doesn’t use a String class like C++ and Processing. This might seem like a big deal at first, but you’ll realize after working with Arduino for a little while ...
not intend to be a real radio for exigent listeners. However, it is possible to start with it and then, if you wish, you can include some devices to the circuit to improve, for example, its sensibility beyond other desired features.Click here to see a complete set of schematics and ...
