Introduction to Microcontroller Board (DSP/ARM/FPGA) 2022

Date: 20-12-2022 ClickCount: 981

The board for embedded system development is formed with development, which includes hardware interface components such as input/output devices, central processor, memory, bus and external resources. It is generally designed and developed by development engineers according to specific needs, and can also be customized according to customer requirements. Common microcontroller boards are DSP, ARM, FPGA, etc.

 

 

What is DSP/ARM/FPGA Borad

 dsp board

DSP board

 

DSP board, is around the function of DSP research and development, the launch of the circuit board for DSP chip development, and provide schematics and source code to customers. DSP especially TI's DSP market share is the largest, has a wide range of customers. In the DSP development board Easy series DSP board, including Easy2812 development board, Easy5509 development board, especially suitable for students to learn to use. Also launched QQ series development boards, including QQ2812 development board, QQ5509 development board, etc., suitable for company R & D personnel use.

 

ARM board

 

ARM board, that is, the British ARM (Advanced RISC Machines) company's core chip as the CPU, while additional peripheral functions of the embedded board, to evaluate the functions of the core chip and research and development of various technology companies' products.

 

ARM board has many functional interfaces after adding peripherals on the basis of CPU, such as extended TFT-LCD, LVDS interface, touch screen, VGA, matrix keyboard, external bus interface, CAN, SPI, PWM, high-speed USB HOST\Device, SD card, RS232\RS485 serial port, audio, MIC and other common interfaces, leading domestic The leading domestic embedded solution manufacturers often have multiple core platform ARM board so that the technology companies R & D engineers can easily test the ARM board and R & D company products, through the board information documents can quickly develop the company's products, shorten the R & D cycle.

 

FPGA borad

 

FPGA boards are facing new design challenges in the automotive industry as system solutions based on MCUs, custom ASICs and bulky wire harnesses to implement engine and control electronics have evolved to near the limits of their technology and applications.

 

To rapidly implement these highly integrated and ever-changing systems, FPGAs, which enable rapid time-to-market, give automakers the flexibility they need to upgrade system hardware in the field without the need to perform costly rework and component replacement. As a result, FPGAs are now used in automotive electronics, ranging from design verification to manufacturing and service. As space becomes increasingly valuable in automobiles, the ability of programmable logic to integrate many different functions on a small single-chip solution is also attractive.

 

The Difference Between Microcontroller Board and Microcontroller

 

1. Microcontroller board: It is a board used for embedded system development, including a series of hardware components such as central processor, memory, input device, output device, data path/bus and external resource interface. In the general embedded system development process, the hardware is generally divided into two platforms, one is the development platform, one is the target platform that is the development board. The development platform described here refers to the use of a computer that is connected to the target platform through a transmitted interface, such as serial, USB, parallel, or network.

 

Microcontroller boards are generally ordered by embedded system developers themselves according to their development needs, and can also be designed by the user's own research. Development board is for beginners to understand and learn the system hardware and software, while some development boards also provide the basic integrated development environment and software source code and hardware schematics, etc.. Common development boards are 51, ARM, FPGA, DSP development board.

 

2. Microcontroller: is the chip, such as 51 microcontroller, AVR microcontroller, stm32 microcontroller microcontroller development board is integrated with a microcontroller chip and some modules that can achieve specific functions of the board For example, Wu Jianying microcontroller development board, can be used to learn, there are many experimental functions, the microcontroller is just a core chip above.

 

3. The difference: microcontroller is an 8-bit microcontroller chip, it is the core device of the development board, microcontroller development board is the commonly used peripheral devices of the microcontroller integrated into a circuit board, together with the microcontroller to form a development system, you can write programs on the development board to control the surrounding devices to achieve the corresponding function, in order to achieve the purpose of learning microcontroller.

 

The specific use of different development boards will be a little different, but generally need to be connected to the computer, some need to have a serial driver (serial port for downloading programs to the microcontroller).

 

How to Use Microcontroller Board

 how to use microcontroller board

1. First look at the development board schematic, that is, what are the available modules on the board

 

2. In the data CD-ROM to find the description file, generally in the root directory will have a text file, read carefully

 

3. According to the instructions in the file, step by step, from the shallow to deep learning, it is important to practice more

 

4. Programming software installed, first find a supporting program burned into the microcontroller, it is important to first find a sense of control development board

 

When we download the program to the microcontroller, you need to do some preparation matters:

 

(1) Open the development board, please first look at the board's related accessories. We need to use the USB cable, with the rest of the accessories in the relevant experiments need to be used: as shown in Figure 2

 

2) Connect the Mini USB to the microcontroller development board.

 

3) When we download, the microcontroller development board needs to do some jumper cap settings.

 

The USB cable is linked to the development board; the jumper cap of the power supply is shorted to the right 5V. If you want to use 3.3V, the jumper cap can be shorted to the left, note that the microcontroller may not work properly; when using 51 microcontroller, the jumper cap is shorted to the right. If you use the ARM module, then short to the left (the board has 51 and ARM label). Microcontroller work and download need to be connected to the crystal.

 

When use the USB cable to download, these two jumper caps need to be shorted to the left. If you use the 9-pin serial port, please short to the right (9-pin serial port download, you can not use the Puzhong, can only use the official STC-ISP). Reset button. Jumper cap is shorted to the bottom, at high level. If you are using avr microcontroller, you need to short to the upper low level out. (The development board is marked H and L). The microcontroller is installed. Note that when the microcontroller is installed, pay attention to the gap facing up. If the installation is reversed, it will short circuit and burn the board.

 

5. If you encounter problems, you can read more information, read a book, or find the corresponding agent to seek technical help, such as EN's microcontroller can find the corresponding technical articles or engineer's contact information in their company's official website, they can provide one-on-one technical support.

 

What is the Use of Microcontroller Board

 microcontroller board

1. It can be used as a burner (i.e., programmer), write their own written programs into the microcontroller.

 

2. It can use some hardware on the development board

 

3. The use of a microcontroller development board can be prepared for different programs to achieve a variety of functions, without having to weld a board for an experiment.

 

4. In the open single-chip development board design, debug the program, it can be easily ported to the product, only sometimes to make appropriate changes, such as port settings, because after all, the development board and the product board can not be identical.

 

5. The use of microcontroller development board to save a lot of resources and improve our learning efficiency. To provide a good platform for us to better learn microcontroller.
