Most people do not understand the knowledge points of this article "MicroPython build cloud adder method is what", so the editor summarizes the following content to you, detailed, clear steps, with a certain reference value, I hope you can get something after reading this article, let's take a look at this "MicroPython cloud adder method is what" article it.

one。 Experimental device

TPYBoard_V201 development board

II. TPYBoard_V201 development board

TPYBoard_V201 is a MicroPython development board made by TurnipSmart Company on the basis of MicroPython licensed by MIT. It is based on STM32F405 single-chip microcomputer and transmits data through USB interface. The development board has built-in 4 LED lights and on-board V201 network port function, which can work normally between 3.3V-10V voltage. It can be said that this development board is not too hegemonic in terms of network stability, and other hardware resources on the board are also very rich, such as 1-wire, i2C, SPI, serial port and other interfaces. This time we will use the function of serial port.

The required devices are introduced above, and let's talk about the environment needed for the experiment. All you need here is to be able to power the development board and to support a wired network connection (which can connect the development board to the Internet).

The first step of the experiment is to power the development board and plug in the network cable, and see that the green light on the V201 network port lights up, indicating that the network has been connected.

three。 Configure V201 network port

This step is to set the destination address, local port, baud rate, data bits, parity bits and other information of the V201 network port module.

Then let's talk about the basic logical flow:

1. Confirm that the power supply and network are in good condition

two。 To confirm that the network is intact, the next step is to carry out transmission and processing. On the premise of ensuring that the network is unobstructed, set serial port 6, that is, Y1 and Y2. The specific baud rate should be determined by referring to the baud rate you previously set to the V201 port.

3. What needs to be said here is that when this development board uses the Ethernet function, the three pins Y1 and Y2 are occupied, in which Y1 and Y2 are serial ports and perform communication functions.

4. Here we need to introduce that Y3Jing Y3 is the setting pin of V201 network port. When Y3 is not in low power level, V201 network port is in normal working state, which can be uploaded or configured through the network using setting software. When Y3 is at low power level, the V201 network port enters the serial port configuration mode, which can be configured through the serial port using the setting software. Data cannot be uploaded at this time.

5. After all the above work is completed, all that is left is to monitor whether serial port 6 has data at all times.

6. When the data is first received, add one to the counting variable and use the registered variable to save the data

7. When the data is received for the second time, add one to the count variable and use the register variable to save the data

8. When it is determined that the counting variable is 02:00, add the data received two times.

9. Finally, we only need to send the result of the two additions from serial port 6.

four。 Physical objects and data maps

The following is the physical picture and data monitoring screenshot of my experiment. I opened a simulated customer port on my computer. Although low is a little bit, the effect is the same.
