Boss let myself to choose the appropriate chip (function as simple as possible), and then draw yourself PCB plate welding, to complete a simple, reserved some interface, their outward expansion module, but have no idea when selection, online baidu to level are mostly some commercial products of the design of the introduction to the use of or like 51/32, who can help me?

CodePudding user response:

Main such questions, don't know how to answer,

The original poster should put forward their own needs, or the board of applications, need what peripherals,

I really don't know, suggest to teach yourself related chip based tutorial, learn about the resources of the chip,

CodePudding user response:

Is not so much, do your own development board just in order to use the learning modules to extend the process, no specific products or used for

CodePudding user response:

Just study, suggest to buy a finished product development board to learn, because they never learn, not verify function sheet could lead to a lot of problems (hardware problems, driver, the program logic),

After learning the basic tutorial, can try to do the development, or play board,

CodePudding user response:

Estimation is want you to practice the ability of drawing board, can try to be a STM32F103 development board, main board with MCU, power circuit, crystals, RS485 circuit devices, such as the other is a serial port, I2C, USB interface, such as set aside, for subsequent external other modules,

CodePudding user response:

Simple requirements, in 103 this resource will be enough, it as for IC, there are all sorts of reference of these online again together the various components of the peripheral circuit is the board

CodePudding user response:

The complexity of the see you, simply choose a single-chip microcomputer, high-end choose ARM - Linux this point, Beijing to just pick an imitation of the newsletter for the store I feel good

CodePudding user response:

Suggest stm32F103RCT6

CodePudding user response:

Look at what you want to achieve the function, and then according to the function to find specific chip implementation scheme
