Input and output in a microcontroller are achieved by simply reading or writing a port data register. If a binary code is presented to the input pins of the chip by an external device (e.g. a set of switches), the data is latched into the register allocated to that port when it is ...
In order to read and analyze serial port data, there are a number of terms and concepts that you should be familiar with around the RS232 protocol. From understanding electrical voltages to pinouts, having this knowledge will make reading serial data from a com port and analyzing all the moni...

第一个函数 GPIO_SetBits(GPIOD,GPIO_Pin_2); 当该函数被程序执行的时候,会改变I/O对应寄存器的值,让I/O口PD2输出电压3v3,于是led就被点亮了. 第二个函数 GPIO_ResetBits(GPIOD,GPIO_Pin_2); 当该函数被程序执行的时候,就会把寄存器的逻辑电平改成0,那么I/O口PD2实际的输出电压就会变成0v了,于是LED也...

Then an IO stream can be opend for reading and writing data. Once the application is done with the port, it must call the close method. Thereafter the application must not call any methods in the port object. Doing so will cause a java.lang.IllegalStateException to be thrown. ...
