BM8563 Example
This example shows how to use the BM8563 RTC driver to set and get the time.
How to use example
Hardware Required
This example can be run on any ESP32 board, the BM8563 is connected to the ESP32 via I2C. This example uses the following I2C configuration:
SDA GPIO 21
SCL GPIO 22
Frequency 400KHz
Which is a working configuration on the ESP32 TimerCam.
Note: on the ESP32 TimerCam, you’ll need to use a flash baudrate <= 1500000.
Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
idf.py -p PORT flash monitor
(Replace PORT with the name of the serial port to use.)
(To exit the serial monitor, type Ctrl-].)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
