Keyboard input - I/O input experiment I. Experimental purpose To correctly read the pin status of PIO, so that when a key is pressed, the LED lights up, otherwise it goes out. II. Experime...[Details]

PCA is a module and a hardware structure, as shown in the following figure The 16-bit PCA timer/counter is equivalent to timer 0/1. It will automatically increase by 1 after each clock cycle. The c...[Details]

SPI, the full name of Serial Peropheral Interface, is a high-speed, full-duplex, synchronous communication bus. SPI is commonly used for communication between microcontrollers and E2PROM, FLASH, re...[Details]

The serial port of LPC2138 has a 16-byte receive and transmit FIFO, and the trigger point of the receive FIFO can be set to 1, 4, 8, and 14 bytes. 1) receive When the number of received bytes reach...[Details]

This is a typical relay drive circuit diagram. Such diagrams can be found everywhere on the Internet, and standard textbooks generally have such circuit diagrams. (One of our teachers said that ...[Details]

The control of the servo generally requires a 20ms time base pulse, and the high level part of the pulse is generally the angle control pulse part in the range of 0.5ms~2.5ms. Taking a 180-degree ang...[Details]

The working principle of the 51 microcontroller is the same as that of many microcontrollers, and they all follow the von Neumann architecture, that is, the data area and code area are separated. The...[Details]

The main functions of a handheld computer (HPC) should include: computing, data storage, input and output, data communication and system expansion. The organic combination of software and hardware is...[Details]

Problem Description: When working on a BCM project, I found a problem. That is, at the moment of power-on, I found that the light flickered. From the phenomenon, it should be the default value of the...[Details]

1 Introduction Supporting C language is a basic requirement for programming of almost all microcontrollers, and of course the SPMC75 series microcontrollers are no exception. The design of the ...[Details]

In fact, the hardware SPI of stm32 itself is also very easy to use, but I still want to use software to simulate the timing of PSI.    SPI is a high-speed, full-duplex, synchronous serial communicati...[Details]
