RTC Real-time Module(EF05034)
34. RTC Real-time Module(EF05034)#
It is a clock module which can achieve counting for year, month, day, hour, minute and second by using the DS1307 clock chip.
Designed in RJ11 connections, easy to plug.
|Type of Connection||Analog output|
34.6. Quick to Start#
34.6.1. Materials Required and Diagram#
Connect the RTC Real-time module to the IIC port and the OLED to another IIC port in the Nezha expansion board as the picture shows.
34.7. MakeCode Programming#
34.7.1. Step 1#
Click “Advanced” in the MakeCode drawer to see more choices.
We need to add a package for programming, . Click “Extensions” in the bottom of the drawer and search with “PlanetX” in the dialogue box to download it.
Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.
34.7.2. Step 2#
34.7.3. Code as below:#
The seconds read by the RTC Real-time module displays on the OLED screen.
34.8. Python Programming#
34.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add ds1370.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add ds1370.py from the unzipped package of PlanetX_MicroPython.
34.8.2. Step 2#
from microbit import * from ds1307 import * ds1307 = DS1307() ds1307.Second(second=0) while True: display.scroll(ds1307.Second())
The seconds read by the RTC Real-time module displays on the micro:bit.
