Comparison of main ZigBee chip vendor's ZigBee solution competitiveness 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 + M

a method of measuring memory chip with multimeter In the motherboard and memory data pins are 64, d0-d63, in order to protect the memory of the data bits, in the d0-d63 of these 64 bits of data are added a resistor with a small resistance to the current limiting effect. The main principle of the tester is to use the program to repeat the test memory chip each data bit pin, to see if there is no breakdown o

I. Summary The experiment aims to understand the basic principles of CHIP-SEQ. By imitating the process of the literature "targeting super enhancer associated oncogenes in oesophageal squamous cell carcinoma", we learned to download data using NCBI and EBI databases, Familiar with the basic operation of Linux, and use the R language to draw, using Python or shell to write scripts for basic data processing, through the FASTQC, Bowtie, Macs, Samtools, R

"abstract" in order to reduce the development difficulty of DSP system software, to ensure the real-time nature of the system, shorten the development cycle, the embedded real-time operating system Μc/os-ⅱ porting to the DSP chip is a common method at present. This paper introduces the characteristics of embedded real-time operating system (Μc/os-ⅱ), and analyzes the porting method of Μc/os-ⅱ operating system in the current popular DSP

How to interconnect single-chip serial communication rxd with txd Category:8051 2012-04-0711: 35 Read by 348 Comment (0) Favorites Report Reprinted from: http://blog.csdn.net/sdwuyulunbi/article/details/6632382 I believe many people are confused about how to connect rxd and txd when the microcontroller communicates with a computer or chip. In some circuit diagrams, some are

This article tags: Nordic Chip MacOSXI tried to compile the Nordic Nrf5x Series project with GCC under Mac OSX, but found that the compiled hex could not be burned, so it was down for a while. Now we have to pick it up and solve the problem.The following are the compile steps: Nordic official website Download SDK:NRF51822SDK The chip of the NRF5X series running ble is divided into tw

[CCID news] Sun Microsystems announced the upcoming release of ultrasparc iv + chip. The IV + chip-based server runs twice as fast as the ultrasparc IV server. The new chip, codenamed "Panther", will detail details about the high-end processor on Tuesday. Like the current ultrasparc IV chip, ultrasparc iv + is impl

chip design is divided into front-end design and back-end design, front-end design (also known as logical design) and back-end design (also known as physical design) does not have a uniform strict boundaries, involving the process-related design is the back-end design. 1. Specification Development Chip specifications, like feature lists, are the design requirements that customers prese

I have summarized two types of chips: master and slave ). This method is just for convenience. Okay. Let's take a look at the master. Generally, this role can be called a SoC (system on chip), that is, a system-level chip. SOC can be divided into three types: MCU (micro control unit), MPU (micro processor unit), and DSP (DSP, there is no clear line between MPU and MCU, but I think this distinction is still
