Comparison between parallel interface and serial interface of SRAM memory

External SRAM is usually equipped with a parallel interface. Considering the memory requirements of most SRAM based applications, it is not surprising to choose a parallel interface. For high-performance (mainly cache) applications that have (and are still) using SRAM, parallel interface has obvious advantages over serial interface. But that seems to be about to change. […]

Design points and skills of motor drive circuit

1、 In the design of motor drive circuit, the following points are mainly considered: Function: does the motor rotate in one direction or two directions? Need speed regulation? For unidirectional motor drive, only a high-power triode or FET or relay can directly drive the motor. When the motor needs bidirectional rotation, an H-bridge circuit composed […]

How to distinguish USB interfaces of different standards

USB type-C is a popular new interface standard, but it is not easy to explain it clearly. Type-C is described as a “supplement” to 10Gbps USB 3.1 configuration, but it can also support USB 2.0 or 3.0. USB 3.0 itself is now called “USB 3.1 Gen 1”, which is another confusing place. In order to […]

What are the advantages of USB type-C interface over other interfaces

We are all concerned about the development of mobile phones, but we have ignored the innovation of many important components around them for a long time. Like USB cable, few technologies or transmission standards are as closely related to our life as universal serial bus, even to the point of no failure. No matter how […]

88e1512 network communication system based on rgmii interface

1、 Foreword There are many types of phy chip interfaces in network communication. PHY chip rtl8211eg that has been in contact with gmii interface before. However, there are many gmii interfaces. This paper uses 88e1512 of rgmii interface to build a network communication system. This kind of interface bus has a small bit width, which […]

Python interface file instructions

First, the python interface file is in the python folder under the installed Darknet directory. Open it and you can see it The darknet.py file here is the python interface Open with the editor to view the last part of the code: It is very simple to use. First load the network configuration and then […]

Signal edge parameter measurement scheme based on CAN node

The CAN bus design specification has strict regulations on the parameters of the signal edge of the CAN node. If it does not meet the specification, it is easy to appear abnormal working state after the field networking, and there are communication failures between the nodes. The specific requirements are shown in Table 1, which […]
