I have basically understood the basic knowledge of IIC in the previous blog. In fact, I still have a few blind spots, because after I learned 51, I got in touch with the MSP430, and then used 430 as a project, I am not very familiar with ok6410 directly, so I will first list some of my knowledge blind spots ~~ ·
1. When we analyze this program, we need to print the data information in the ROM through the serial port. Therefore, the serial port Initial

Comparison of main ZigBee chip vendor's ZigBee solution competitivenessAt present, there are major ZigBee chip vendors (2.4 GHz), including Ti/chipcon, Ember (ST), jennic (), Freescale, and microchip.Currently, ZigBee technology provides three methods:1) ZigBee RF + MCU, such as Ti CC2420 + MSP430, freesclae mc13xx + GT60, microchip mj2440 + pic mcu.2) Single-Chip Integrated SOC,
I am about to go out and look for a job. I don't know if I can use single chip microcomputer in the future. I will summarize my self-taught opinions. This gives beginners and fans a deeper understanding! The sequence of introduction is probably AVR, MSP430, and lpc210x.

I used to repost others' blogs all the time. Today, we can finally post original things and celebrate it. First, we attached the Development Board "Beautiful photos" created by three of our teachers and brothers. This board was referenced by the friendly arm micro2440.
This board has condensed our painstaking efforts ~~. Senior spring students are more familiar with embedded systems than we are. The three of us are very interested in embedded systems (I am a bachelor and I am engaged in softwar
Summary:
MSP430 single-chip microcomputer 8 kV electrostatic dead machine,
Arm will not crash much, but static electricity is easy to penetrate into arm's Io,
Then, the I/O short-circuit chip is exposed to heat. When the chip is damaged, some chips are cracked,
However, it can be restored after power failure,
No external guard is used,
Reset after static electricity is not easy to enable, must be powered on,
According to the Inter
educational device, many developers have begun to use this credit card-sized computer in Iot projects. Although the complete hardware specification is not open-source, most software and documentation are open-source. Raspbian is a popular Raspberry Pi Operating System Based On Debian, a Linux release.

task, and it's a good idea to browse the ENC28J60 manual before you start. In addition, we need to read the TCP IP related knowledge carefully, recommend a book "Embedded Internet TCP/IP foundation, implementation and application." Embedded development is an iterative process, which refers to the Avrnet project and the relevant examples of the struggle Development Board. "Avrnet Project URL link"
Although the MCU used in the Avrnet project is ATMEGA32, it can be conveniently ported to other MCU
". Rios was first unveiled in 2013, derived from the Feuerwhere project. It is designed to be both friendly to the developer and resource-friendly (i.e., less resource intensive). It supports a variety of architectures, including MSP430, ARM7, Cortex-m0, CORTEX-M3, CORTEX-M4, and standard x86 PCs.

Developed to this day, has become a set of embedded engineers training, high-end software development talent practice, software technology development, IT consulting services in one of the high-tech enterprises.Over the past 10 years, China embedded education has always focused on developing and transporting high-quality software talents for the high-speed development of the Yangtz
The original project was to use the MSP430 single-chip microcomputer. one end of the key was connected to the single-chip microcomputer's IO port, and the other end was directly connected to GND. When no key is pressed, the IO port reads a High Level. when the key is pressed, the IO port reads a low level.
The EFM32 single-chip microcomputer is still the same as the key circuit. During the test, it was found that when several buttons are pressed, the
data sending and receiving. ATmegal28L exchange data and send commands with CC2420 through the CC2420 SPI interface (CSn, SO, SI, SCK), reset the chip using the RSTn pin, and enable the CC2420 voltage regulator using the VREG_EN pin, make it generate the 1.8 V voltage required by CC2420, so that CC2420 enters the normal working state. CC2420 communicates with each other through a single pole antenna or PCB antenna. Figure 4 shows the overall node architecture.
