Описание товара
Hardware size:
1. Network communication data (WFi and Ethernet routines) 1: Onboard WIF, mobile APP control development board, open the intelligent era WiFi performance profile: 1, ESP8266 is a serial port type WIFI, the speed is relatively low, can not be used to transmit large amounts of data such as images or video. It is mainly used in applications where data transmission is relatively small, such as temperature and humidity information, and the switching amount of some sensors. 2. In the experiment of WIFI transparent transmission, our measured data is: in the LAN, WIFI works in STA mode. The MCU sends data to the host computer through ESP8266, sending 1120 bytes each time, the time interval is 100ms, very stable, and the standby time is 24 hours. 3. Application areas: Internet of Things, intelligent community, modern agriculture, modern medical
2: APP profile, only supports Android does not support 10S
2-1: Distribution network
Burn the supporting program, after the WIFI signal is successfully configured, search the ESP8266 on the mobile phone.
The WIFI signal is emitted. The signal name is: BinghuoLink, which can be connected without a password.
Set the password yourself in the program). Run the installed mobile phone app, and use it on the APP.
The IP and port have been initialized, just click on the connection, after the connection is successful, there will be
Show, then you can implement the control development board (APP source is about to open source, perfect)
2-2: Interface
APP has two interfaces, the front is the interface that controls the development board hardware, and the second is WiFI.
Transparent transmission interface, that is, the APP sends information to the development board, and then the development board sends the information back to the APP.
EMWIN renderings, detailed screenshots of supporting routines:
1. The integrated routine requires a bare board + 3.2 inch LCD screen (or 5 inch capacitive screen) to work together.
Use, single bare board can not achieve this experiment (screen needs to be purchased separately)
2, the following screenshots are 3.2-inch screen effect, resolution 320 * 240.5-inch screen resolution is 800 * 480 (5-inch renderings again do not demonstrate)
3, the following pictures are obtained by the screenshot function, that is, the LCD screenshot routine (BMP format)
1. Comprehensive routine interface, a total of 10 sub-applications (you can add applications yourself)
After entering the main page, the development board is normal. Available from
Try to open each app and try to use it. There are some
APP requires an external hardware module for normal use
2, KEY breathing lamp application
1: Run the KEY APP to control the LEDs using the buttons on the board.
After entering the APP interface, press the KEY1 button on the development board to control the LED to turn off.
You can also click on the two "KEY" buttons on the interface. When the button is pressed, it will
A corresponding LED light is illuminated. Pull the slider to
Control the LED light to run as a running light for a short period of time
The position of the slider is related to how fast the LED light flashes.
2: Click the "Touch Calibration" button on the interface, it will enter the touch correction interface, enter the interface and click the screen.
Then follow the prompts and click on the small circle that appears on the interface. After the calibration is successful, it will return to the main interface.
3, Breathing breathing light application
Run the Breathing APP to enter the RGB lights on the board.
Line coloring. The three parameters on the APP interface represent
R, G, B values of the RGB888 color format, by sliding
The bar can set the parameter value, the circle below the interface will be the three
The color of the parameter synthesis shows that the RGB lights on the board
It will also change the color.
4, ADC Converte application
The ADC APP can collect the voltage and display the voltage as a waveform. Rotate the potentiometer on the upper right side of the board.
Changing the input voltage also changes the voltage detected on the APP.
5, EEPROM application
1. EEPROM APPI can be on the EEPROM on the board
Read and write data, when you open the app, it will automatically
Write to the 0-255 address of the EEPROM in turn
Automated testing of data with the same address
The test results are displayed at the bottom of the screen.
2: Users can write custom to specific addresses
The data. After clicking the input box, the button will pop up.
Disk, you can use the keyboard to enter numbers
6, Clock real time clock
The Clock APP uses the RTC function of the STM32.
If you connect the battery holder on the development board to the battery, the development board
RTC will continue to run after disconnecting the main power, next time
When you open the Clock APP, you will see the update time.
(The battery holder is below the LCD screen and the battery model is the battery.
The model number is: CR1220. The development board does not have a matching battery by default. )
7, USB analog U disk
USB APP is an analog U disk program that can
The FLASH on the board is simulated into a USB flash drive, on the computer
View the files on FLASH in the form of a USB flash drive
8, WiFi application
1. Use WIFI APP to perform WIFI communication and demonstration
Transfer text data to and from the server using the TCP protocol
2. This experiment requires wireless routing support, and the computer and
STM32 should be connected to the same router, router
The gateway address is 192.168.1.1. If the address does not match,
Need to modify the program
9, Humidure temperature and humidity application
Humiture app can be used to display detected
Temperature and humidity data. Needed before powering up
To connect the DS18B20 to the upper right corner of the board
Temperature sensor or DHT11 temperature and humidity sensor
If the connection is normal, you can open the app directly.
See data for DS18B20 or DHT11
(DS18B20 or DHT11 modules need to be purchased separately)
10, Camera application
Camera APP is used to develop the board expansion camera function. Just above the development board is
Camera interface, can expand our fire eye 0V7725 camera. Normal LCD screen
The data captured by the camera is displayed in real time for real-time monitoring.
(This rendering shows the 0V7725 camera, you need to buy it separately, click to view
11, Calculator application
Caculator is a calculator program with normal
The calculator is no different. Nothing to note, feel free use
12, User application
These two User are user-defined functions and are
No function application added, here we reserve to add to the user
Add the features you need (refer to other application programming implementations)
13, Phone application
PHONE is a phone dialing application. The application needs
Use GSM module together, and GSM module needs
To access the SM card, the wiring method is shown below.
(GSM module needs to be purchased separately)
14, Message application
1, Message is to send SMS application,
It also needs to be used in conjunction with the GSM module.
2, in the application interface you can view the draft box
In the text message, you can also click "new..."
Create a new text message in a column, in the SMS editing community
You can write and send a text message.
