Linuxat instruction set

AVR is a single chip microcomputer of ATMEL company, with RISC structure and single instruction cycle. The representative models are AT90S series.

AVR MCU is a RISC MCU with reduced instruction set introduced by ATMEL in 1990s, similar to PIC. It adopts Harvard structure. In this way, AT89C52 is equivalent to Pentium CPU of intel's complex instruction set CISC, and AT90S85 15 is equivalent to K7CPU of AMD's reduced instruction set RISC.

Explain the principle of 8266 chip?

8266 chip is a low-cost, high-integration Wi-Fi module, which is often used in Internet of Things devices. The following is the principle explanation of the 8266 chip:

fundamental/essential component

The 8266 chip includes a main processor (ESP8266) and a Wi-Fi chip (ESP8266EX). The main processor is Tensilicone Axtensalx106 core, which can run at 80MHz or 160MHz clock frequency, and has 64KB SRAM and external flash interface. Wi-Fi chip provides the ability of wireless network connection.

Mode of operation

8266 chip can communicate with other devices through UART or SPI interface. The main processor can run according to the instruction set, communicate with external devices through serial port, or use C language for programming control. The main processor communicates with the Wi-Fi chip through SPI interface.

Wi-Fi connection

When using 8266 chip for wireless connection, it is necessary to configure the SSID and password of Wi-Fi module to connect to a specific network. This process can be achieved by using the AT instruction. After the connection is successful, 8266 chip can transmit data through TCP/IP protocol.

Software support

In order to facilitate developers to use 8266 chips, the open source community provides many support libraries and sample codes, such as ArduinoIDE, NodeMCU and so on. These tools allow developers to quickly design and test prototypes, thus accelerating the development of Internet of Things applications.

Generally speaking, 8266 chip is a low-cost, high-integration and easy-to-use Wi-Fi module, which is widely used in the field of Internet of Things. The open source community provides rich support tools for developers to design and test rapid prototypes.

Can I use AT instruction set in serial debugging assistant?

Yes, send the AT command you want to send in the assistant, and then press Enter to receive the reply message of the AT command in the assistant's receiving area. The landlord can also use super terminal, which is also very easy to use.

What does the at command mean at runtime?

At command has two interpretations: one is the modem command language, and the other is the command line for scheduling tasks in Windows.

AT is to noTE thAT at instruction set is sent from terminal equipment (te) or daTA terminal equipment (DTE) to terminal adapter (ta) or data circuit terminal equipment (DCE).

AT commands are sent by TA and TE to control the functions of mobile station (MS) and interact with GSM network services.

Users can control calls, short messages, phone books, data services, faxes, etc. through AT commands.

What is tmip5600 used for?

Tmip5600 is an ordinary dial-up modem.
