This article mainly introduces "how to achieve the caller ID function in Micropython". In the daily operation, I believe many people have doubts about how to achieve the caller ID function in Micropython. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to achieve caller ID function in Micropython". Next, please follow the editor to study!

1. Introduction of TPYBoardV702

TPYBoardV702 is the only MicroPython development board on the market that supports communication functions: it supports Python3.0 and above versions to run directly. Support GPS+ Beidou dual-mode communication, GPRS communication, SMS function, phone function; board temperature and humidity, photosensitive, three-axis accelerometer, buzzer, LCD5110 display screen. Communication test service platform is provided free of charge.

Second, use TPYBoardV702 to receive the prompt call, and display the incoming call number and the caller's name on the display screen.

1. Specific requirements

Use TPYBoardV702 to receive the prompt call, and display the incoming call number and caller's name on the display screen.

2. Required devices

TPYBoardV702 development board

5110 display screen

One Gsm mobile phone card

TPYBoardV702 develops board GSM communication function without external connection.

3. Introduction to the function and use of onboard communication

The overall highlight of the V702 development board is the on-board communication function, which can be used as long as a usable mobile phone card is inserted into the card slot of the development board (does not support telecommunications).

The communication functions on the development board include phone, SMS, GPRS and other functions. In this experiment, we only use the phone function.

The communication function on the development board has been well designed. When receiving an incoming call, we will actively send the information of the incoming call through serial port 4. In this way, as users, we just need to process and display the data accordingly.

Third, the main process of production

Let's start with the previous picture, and then we'll talk about the code.

1. Production process

(1) the first thing we need to do is to plug the 5100 display screen into the 5110 display interface of the 702 development board.

(2) after the above work is completed, we need to use the main class library, 5110 class library, and we need to copy the .py file of this class library to the drive letter of the development board.

(3) after completing the above work, we begin to edit the main (). Py file code

(4) declare and define the class libraries that need to be used

(5) define the variables we need to use.

(6) declare and define the interfaces we need to use. Here we mainly use spi1 and serial port 4. When declaring serial port 4, we need to set the serial port baud rate to 115200.

(7) Let's start the writing of the main function. In this experiment, we use the display. We initialize the display at the beginning of the program.

(8) after completing the initialization of the display part, the most important thing we need to do is to define the "Y6" pin as the output, then pull the "Y6" pin down for more than two seconds, and then pull the pin up. Because the "Y6" pin is a switch that controls the opening of the entire on-board communication system, if we do not use the communication system at ordinary times, in order to save power consumption, the on-board communication system is turned off and only need to lower the "Y6" pin for more than two seconds.

(9) when the red inline LED light on the development board is flashing quickly, it means that the onboard communication system is starting, and when the red inline indicator light ends the flash (if the mobile phone plugged into the development board slot is available, the indicator is in slow flash state), it means that the onboard communication system has been activated.

(10) after the above work is completed, the preparation work has been completed, and all that needs to be done is to monitor whether data is sent from serial port 4. When it is detected that data is sent from serial port 4, the data is judged and processed accordingly. And display it on the display screen.
