Arduino的 String 类提供了 toInt() 方法,可以将字符串转换为整数。 cpp int number = inputString.toInt(); 验证转换结果是否正确: 在转换后,你可以通过比较转换前后的值来验证转换是否成功。例如,如果转换后的整数再转换回字符串与原始字符串相同,则可以认为转换是成功的。 cpp String convertedBackToString =...

String to Integer conversion Reads a serial input string until it sees a newline, then converts the string to a number if the characters are digits. The circuit: No external components needed. created 29 Nov 2010 by Tom Igoe This example code is in the public domain. ...
If you read the first binary sequence backwards (right to left), you get the second sequence. You may use bitreverseOneByte() or bitreverse32Bit() for this.Sending old MSB codes without conversion can be done by using sendNECMSB(), sendSonyMSB(), sendSamsungMSB(), sendJVCMSB().Errors...
