This article mainly introduces Python how to achieve DIY electronic clock related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that everyone after reading this Python how to achieve DIY electronic clock article will have a harvest, let's take a look at it.

First, the purpose of the experiment:

? Learn the method of extending the simple Icano interface in the PC system

? Learn TurnipBit splicing programming

? Learn the connection mode between TurnipBit expansion board and DS3231 clock module

? The use of learning clock module

Second, the required original devices:

? TurnipBit together

? TurnipBit expansion board

? one DS3231 clock module

? Some DuPont lines

? one usb data cable

Third, the experimental principle:

1. The principle of DS3231 clock module

DS3231 (figure 11-12) is a clock module, which is like an electronic clock with its own battery. When the time is set, the DS3231 will go automatically. The communication between the DS3231 and the development board is completed through the I2C interface. I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips Company. It only needs SDA (serial data line) and SCL (serial clock line) to transmit information between devices connected to the bus. Both SDA and SCL are bi-directional I / O lines. When connecting, you only need to connect SDA and SCL on DS3231 to SDA and SCL on TurnipBit expansion board.

4. Connection method:

The TurnipBit expansion board corresponds to the LED interface as follows:
