Example/-- several examples of Python scripts.

The latest version of Micropython is 1.94. TPY Board adds display screen, infrared and other common interface drivers to use these devices directly.

1.4 what is TPYBoard?

TPYBoard is a compact circuit board that can run MicroPython in bare metal, which provides the underlying Python operating system for controlling various single-chip microcomputer interfaces. It is a development board designed by radish to support MicroPython.

MicroPython includes advanced features such as interactive prompts, arbitrary precision integers, close, list parsing, generator, exception handling, and so on. Suitable for running on chips with only 256k code space and 16k RAM. MicroPython is designed to be as compatible with normal Python as possible, allowing you to easily transfer code from your desktop to a microcontroller or embedded system.

The current TPYBoard has

V10x-mainly the basic TPYBoard development board.

V201-Local area network communication, TPYBoard development board with LAN network port.

V202-wifi communication, TPYBoard development board that supports wifi module.

V702-TPYBoard development board for long distance communication and supporting SIM card.

2. What can MicroPython do?

Since MicroPython can control the single-chip microcomputer with Python language, what the single-chip microcomputer can do can basically reflect what it can do. Or let's take a look at what the monolithic machine is doing?

2.1 Intelligent instrument

Single-chip microcomputer has the advantages of small size, low power consumption, strong control function, flexible expansion, miniaturization and easy to use, so it is widely used in instruments, combined with different types of sensors. it can realize the measurement of physical quantities such as voltage, current, power, frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, element, pressure and so on. The use of single-chip microcomputer control makes the instrument digital, intelligent, miniaturized, and the function is more powerful than the use of electronic or digital circuits. For example, precision measuring equipment (voltmeter, power meter, oscilloscope, various analyzers).

2.2 Industrial control

Single-chip microcomputer has the advantages of small size, strong control function, low power consumption, strong adaptability to the environment, flexible expansion and convenient use. Single-chip microcomputer can be used to form various forms of control system, data acquisition system, communication system, signal detection system, wireless sensing system, measurement and control system, robot and other application control systems. For example, intelligent management of factory assembly line, intelligent control of elevators, various alarm systems, networking with computers to form a secondary control system, and so on. The detection of industrial trap has been substantially popularized and applied.

2.3 Home Appliances

Now household appliances are widely controlled by single-chip microcomputer, from rice cookers, washing machines, refrigerators, air conditioners, color televisions, other audio and video equipment, to electronic weighing equipment and white goods.

2.4 Network and Communication

Modern single-chip microcomputer generally has a communication interface, which can easily communicate with computers, which provides excellent material conditions for the application between computer networks and communication equipment. Today's communication equipment basically realizes the intelligent control of single-chip microcomputer, from mobile phones, telephones, small program-controlled exchanges, building automatic communication and call systems, train wireless communications, to mobile phones that can be seen everywhere in daily work. Trunking mobile communication, walkie-talkie, etc.

Single-chip microcomputer is also widely used in medical equipment, such as medical ventilator, various analyzers, monitors, ultrasonic diagnostic equipment and hospital bed calling system and so on.

2.6 Modular system

Some special single-chip microprocessors are designed to achieve specific functions, so as to carry out modular applications in various circuits without requiring users to understand their internal structure. Such as music integrated single-chip microcomputer, seemingly simple function, miniaturized in a pure electronic chip (different from the principle of tape drive), it needs a complex principle similar to that of a computer. For example, music signals are stored in memory in digital form (similar to ROM), read out by microcontrollers and converted into analog music signals (similar to sound cards). In large-scale circuits, this modular application greatly reduces the size, simplifies the circuit, reduces the damage and error rate, and is convenient for replacement.
