Description: 验证一下位运算是否真是不改变参与变量 的值，同时学习位运算的表达形式。程序很简单，用 P1 口做运算变量，P1.0-P1.7 对应 P1 变量的最低位到最高位，通过连接在 P1 口上的 LED 我们便能直观看到每个位运算后变量 是否有改变或如何改变-To test whether the bit computing really does not change in value of the variable, while the expression of learning-bit computing. The procedure is simple to do with the P1 port operations variables, P1.0-P1.7 P1 corresponding to the lowest to the highest variable bit by connecting the LED on the port P1 we are able to visually see the operation of each bit after the variables have changed or how to change Platform: |
