Online programming scheme of single line SPI

“Serial port download” is the earliest program download method contacted by most engineers, especially the engineers who first used 51 single chip microcomputer. When engineers think of a way to continuously “compress” the chip, they can only download the other way. With the rapid development of the semiconductor industry, the chip integration is getting higher […]

USB type-C will dominate future smartphones in 2020

Maybe many people don’t know what USB typic-c is? USB type-C should be a new interface size. Maybe many small partners think this is a new USB standard, but it’s not. Type-C is only a part of USB 3.1 standard, not a new standard. The USB type-C interface, which can transmit data more quickly, can […]

Detailed explanation of single bus protocol

Single bus is a protocol developed by Dallas company. It consists of a bus master node or multiple slave nodes. The data of the slave chip is read through a signal line. Each slave chip conforming to onewire protocol has a unique address, including 48 bit serial number, 8-bit family code and 8-bit CRC code. […]

Single bus structure

In many single processor computers, a single system bus is used to connect CPU, main memory and I / 0 devices, which is called single bus structure. At this time, it is required that the logic components connected to the bus must run at high speed, so that when some devices need to use the […]

Advantages and disadvantages of single bus

Bus system refers to the channel of transmitting information between the components of microcomputer. In short, under the function of bus controller, the bus is used to control and manage the devices connected to the bus through the bus device interface. Single bus system is the simplest bus system, which refers to the computer system […]

RS232 serial port wiring diagram

RS-232 is one of the mainstream serial communication interfaces and one of the communication interfaces on personal computers. It is an asynchronous transmission standard interface formulated by the Electronic Industries Association (EIA). Generally, RS-232 interfaces appear in the form of 9 pins (DB-9) or 25 pins (db-25). Generally, there are two groups of RS-232 interfaces […]

What is the difference between RS485 and RS232 communication interfaces?

What is RS485 interface The half duplex network composed of RS485 interface is generally two-wire system (there was a four wire system connection method in the past, which can only realize point-to-point communication, which is rarely used now), and most of them adopt shielded twisted pair transmission. This connection mode is a bus topology, and […]
