2016 live the most popular, but behind the surface, how many truly anchor is the anchor? I don't think much. However, it is certain that the live broadcast industry of the firefighter is really actually driving the rapid development of the surrounding industry, such as the microphone used by live broadcast, electricity suits (mouse / keyboard / seat) and other products, even Saving a lot of companies that have suffered, there is already a business that is frequent, but also achieves high-speed profit growth, not exaggerating, these companies are really a pig standing on the air. So today we will talk about the technical solutions for the consumer / industrial electronic products around the popular industries, how to use the smallest cost, earn the biggest profit.
It is well known that small and medium-sized electronic products are basically inseparable from microcontrollers, such as some small toys, menu in smart home series, and these products usually use some versatile MCUs, functional enough, power consumption Low enough, you can implement mobile power, you can achieve cost control, and everyone is not as inner configuration as mobile phones. Only the functions are sufficient, the appearance is coming, I can always win the favor of users, I have to give you today. Recommend this type of MCU, from the latest series of NANO103 microcontroller development boards, which are got in the New Tang seminar, not long ago. Nutiny-EVB-NANO103.
NUTINY-EVB-NANO103 development board
Because the new Tang is more generous, many engineers have also got a lot of new Tang's boards, but you don't think Nutiny-EVB-NANO103 is the same as the previous board, this is a big improvement place, what is the article, article It will be said later.
If you don't have much to say it, I don't know if I have ST, anyway, my own style.
Nutiny-EVB-NANO103 board is very simple, you can see two parts, part is based on the minimum system board of the nano103 microcontroller, and the other is the NU-Link-ME V3.0 debugger, clear, is a V3.0 version , The latest debugger, there is still a large change in Nu-Link-Me, which is not limited to the firmware, and the hardware circuit has improved places. The only nutiny-evb-nano103 board and the New Tang's previous development board can use the main control board and the debugger to use, convenient.
Look at the specific resources of the board.
As can be seen on the development board, Nu-Link-ME V3.0 has a dial switch. Is this dry?
If the schematic is clear, you can understand the function. If you want to implement the serial port, you need to dial the 1, 2, and 3 gear positions of the dial switch to the ON position.
As for the back of the board, there is no device, only some of the via signal expansion port, nothing to say.
MCU development board recommended:
The MCIMX6UL evaluation board is an integrated power management module based on the Cortex-A7 core, which reduces external power supply complexity and simplifies the order of power.
The LPC11U 24 evaluation board is based on the Cortex-M0 kernel is mainly used for consumer electronic peripherals, medical equipment, industrial control and USB audio equipment.
The STM32F469NI exploration kit provides a Cortex-M4 core-based Internet application that requires a killer-level function for Internet applications that require a graphical interactive interface.
NANO103SD3AE microcontroller
Nutiny-EVB-NANO103 development board is equipped with a microcontroller specific model of nano103sd3ae, based on the ARM Cortex-M0 processor, the maximum frequency of 32MHz, using the LQFP64 package, 7mm * 7mm, as shown below.
The NANO103 series microcontroller is a new series of products in New Tang, which can be seen from the official classification, and the previous NANO100 / 102 series is still different, for example, the LCD driver is canceled.
At present, this series of products is only three, except for this on the board, there are two products of QFN33 packages and LQFP38 packages, which are functional, but according to the number of pins, you can let Engineers choose suitable product development according to their own needs, and the comprehensive consideration of the new Tang product line is a big advantage, and serve the Ranked R & D service.
The nano103 microcontroller's hardware system block diagram is as follows.
Development environment
NUTINY-EVB-NANO103 Development Board supports common third-party IDE tools, such as Keil, IAR, Coide, and New Tang Technology also provide engineers with a complete development data package, almost 2.2GB, download address is the packaging of the development board. superior.
The content inside includes an IDE tool, a direct code for the document, a sector of the chip, supports IAR and the Keil IDE tool.
But the pen is better to download it, and the information inside is found to have no Nutiny-evb-nano103 development board. It seems that the board is too new, the information has not been updated to the inside, sincerely speaking, it is recommended that such a big information Attached to an update, such as the 啥 啥 microcontroller or what is the development board.
Finally, the information found directly through the official nano103 series is dispersed. It takes one by one to download, and the tools you need to download are as shown in the red frame shown below.
There is a plate-level support package, download tool, driver and other content, we first need to install the driver, the driver here includes serial port driver and NULINK driver, and Nulink drives according to the third-party IDE tool you use, as follows It is a Keil's Nu-Link driver.
MCU development board recommended:
The MCIMX6UL evaluation board is an integrated power management module based on the Cortex-A7 core, which reduces external power supply complexity and simplifies the order of power.
The LPC11U 24 evaluation board is based on the Cortex-M0 kernel is mainly used for consumer electronic peripherals, medical equipment, industrial control and USB audio equipment.
The STM32F469NI exploration kit provides a Cortex-M4 core-based Internet application that requires a killer-level function for Internet applications that require a graphical interactive interface.
This also includes the Database of the New Tang device and the serial driver of the development board. It needs to be installed. Database is especially noticed, I found the Nano103 Database package in Keil, but I can't download it, or need to go to the new Tang official To download, that is, the above is included in the NU-LINK-Keil driver.
Installation Complete We can use Nu-link and serial port, the NU-LINK debugger, the Dial-Link debugger, the DIP switch holds the default location. If you want to implement the function of the serial port, the DIP switch on the development board 1, 2, 3 gear position Need to dial to the ON position.
As shown below.
At this point we can see the corresponding serial number at the computer.
Set the development board at the NU-Link debugger location, we open the BSP package in the new Tang official download, which contains the latest NUTINY-EVB-NANO103 development board, but the quantity is small.
First look at the LED routines, open through Keil IDE, compile
Set the NU-Link debugger before downloading.
There is no problem with the download debugging.
The result of the program is LED flashing.
In addition, several low-power routines, but unfortunately, the circuit did not specifically leaving a special reserved interface for test power consumption, a little regret.
summary
Since Nutiny-EVB-NANO103 development board is a new Tang new product, mainly for balancing functions and power products, the device is new, the Keil official website does not correspond to the corresponding device Datebase, and the engineer needs to go to the new Tang official download, said To hue, the new Tang's own official website and the forum are well built. If you want to be able to play more affordable domestic MCUs, you can consider the new Tang products, affordable, information in English, and convenient development. If an engineer is looking for a price affordable, functionally universal Cortex-M0 series MCU product, it is not possible to consider Nano103, which will make the cost, profit, and interested engineers can go to the new Tang Taobao shop or can be like the new Tang official Apply for a free development board.
