In order to introduce products to the market, CPU vendors delivers a circuit board that makes customers understand the performance and circuit design of the CPU, the development board will accompany the driver of the hardware interface, the development board circuit board will control the control signal line of the CPU And the general peripheral interface delay. With hardware interfaces and drivers, designers can quickly focus on the development of the product application software, complete the application software to control the peripheral circuit, and deliver mass production after software debugging, complete the development of products.
Due to the high price of the manufacturer promotion, there is no price and low price, and the public players are playing the open source development board? Yes, under the promotion of foreign players, players have a self-contained community for a particular CPU system, and improve the hardware design, improve the standardization of multi-platform development environment and software modules. Open source software and hardware design allows enthusiasts to spend very little costs to complete the function you want to develop.
Most of the foreign open source development board is produced by Shenzhen Electronics Factory. At the same time, the domestic development of open source development boards has also driven several major genres in China's open source development boards:
First, Arduino:
ATMEL AVR CPU. Arduino has its lowest price, the circuit structure is simple, and even players can attract domestic players and college students from DIY circuit boards, as entry-level open source development boards, the most domestic players. All types of switches, sensors, input and output controllers can be done using Arduino.
Second, RaspberryPi:
700M BCM2835 CPU of ARM architecture Based on BoTong. The Raspberry Part is a Linux system, with strong computing power, using SD card as a storage medium, interface has an Ethernet, two USB interfaces, HDMI, and RCA terminal output. The Raspberry Pie is a low price, and the simple construction of the peripheral circuit is well received by players. If you want to develop a networked or video function is an ideal choice, the Raspberry Pist provides Debian, Arch Linux and Fedora. The release of the system For the public download, you can make players don't need to understand the current development of the operating system.
Third, Cubieboard:
ALLWINNER based on ARM Cortex-A8 architecture A10 CPU. Cubieboard is a company produced and promoted in Zhuhai, with 1 GHz CPU, built-in MALI-400MP GPU. Making a Raspberry School Upset Cubieboard has 1080p HD movie playback capabilities as a home media center, and the system of cubieboard has Android 4 ICS, Ubuntu 12.04 Desktop, Fedora, Archlinux, dedicated Debian server operating system to make Cubieboard into one Table server.
As an open source development board in China, Cubieboard attracted many users at home and abroad to pursue high-performance development boards, and the Cubieboard communities have high popularity in many open source development board communities in China. Now CubieBoard has a high-performance open source development version of all-to-express A20, A31, etc.
Fourth, MIXTITLEGARAGER:
Samsung Exynos 4412 quad-core CPU based on ARM Cortex-A9 architecture. Mixtitle Garage is produced for Shenzhen 's fun technology company, and the maximum feature of the MIXTITLE development board has built-in USB interface and TF interface. The development board uses the TF card as a storage device. In addition to the traditional write mode, the TF card can be dial. Write into the firmware system on the PC, and the player is not afraid to debug the software to brush the development board. Mixtitle advanced version of the development board also has built-in snake screws, dynamic sensing, electronic compass, light sensing and proximity sensors.
MIXTILE GARAGE provides Android, Ubuntu Desktop, etc., users can develop corresponding software directly based on the Android system. Based on Samsung's high-performance hunter quad-core CPU, it is a good choice for MIXTITLE as a home media center.
Five, Radxarock:
A RK3188 quad-core CPU based on ARM8 architecture 1.7 g frequency in recent month. The Radxa Rock core developer is the original Cubieboard developer, as the latest developing board, RADXA ROCK built-in 2G DDR3 runs memory, 8G NAND, built-in Bluetooth 4.0, infrared remote control and other high-end hardware configurations.
The development board supports operating systems such as Linux, Android, Debian, and has a GPIO interface that can be programmed by its own programming, thus making advanced players to achieve simple control functions for many small devices at a lower price. At the same time, the lower price of RADXA has enabled senior players to develop high-performance systems and application software at a lower price.
6. Pcduino:
All-scale A10 CPU Based on ARM Cortex-A8 Architecture. The biggest advantage of PcDuino is that his extended interface is compatible with Arduino's signal. A lot of Arduino's expansion board is very advantageous, and it is undoubtedly very beneficial for PcDuino's ecosystem that integrates Arduino. An important feature of the Arduino module is to read and control the sensor. If PCDUINO can use a variety of Arduino modules directly, it seems that you can directly control various sensors directly. Not only can you greatly improve performance, but also produce more creative products.
The emergence of PCDUINO solves the network of Arduino development boards in networks and multimedia weaknesses. PcDuino is a platform for high performance, cost-effective mini PCs that can run Ubuntu and Android ICS. It can output a video to a TV or display screen by a built-in HDMI interface. Pcduino is specifically for open-source communities, that is, hopes that there is a platform that can run a full PC operating system, easy to use toolchain, and an open-bound ecosystem, such as Arduino Shield and open source projects.
