Embedded development board ~ description

1 explain

Embedded development board （Embedded development board） It is one of the carriers of division of labor and cooperation in the semiconductor industry , It provides basic underlying hardware for manufacturers developing products 、 Resources such as system and driver , So that users do not need to invest manpower and time to complete these low-level work .

Simply speaking , Embedded development board is like human brain , Control the operation of other equipment .

2 Selection factors

1. The hardware design of the development board is basically the reference design of semiconductor manufacturers , Domestic manufacturers should be considered when selecting 、 Many factors such as product launch
2. Whether the software of the development board supports perfection , Whether it can support all hardware interfaces on all development boards
3. How strong is the supplier's technical support

3 Development board development and types

Whether it's 8 position 、16 Bit MCU , still 32 Bit embedded processor that can run the operating system , Semiconductor manufacturers have such reference designs . Corresponding , There are many manufacturers who provide development boards to users .

Embedded processors are constantly evolving , Early Motorola semiconductor （ Now Freescale Semiconductor ）68K/Coldfire and PowerPC The dominance of processors has gone forever ,ARM、Coldfire、PowerPC and ADSP And based on MIPS、X86 A hundred flowers bloom in the architecture of embedded processors 、 Processor manufacturers and processor architecture manufacturers each show their magic , Upstream enterprises in the semiconductor industry provide a good opportunity for the emergence and growth of development board manufacturers .

2002 end of the year ,ARM Architecture is popular in China , It brings Dongfeng to many people who want to start a business based on their own embedded technology . Almost every provincial city in the north and south of the river will have development board manufacturers . During this period of time and later companies have a common feature , That is, products are basically based on ARM Processor development , Or emulator class ARM Tools for development . These manufacturers can provide users with development boards with different interface functions , On the whole, it can provide services for manufacturers of electronic products , Accelerate the listing of products of downstream manufacturers in the semiconductor industry chain .

I'm familiar with it now 51 Single chip microcomputer yes 8 Bit MCU ,stm32 Yes, it is ARM Chip 32 Bit MCU .
