DS3231 driver examples

This repository contains examples of using DS3231 driver - ds3231_driver.

Getting Started

1. git clone --recursive https://github.com/HexRx/ds3231_driver_examples.git
2. Do the below steps depend on your platform to compile the example.

NRF52832

The example uses OpenOCD + ST-Link for flashing. P0.6 pin as UART TX debug see the variable NRF_LOG_BACKEND_UART_TX_PIN in config/sdk_config.h.

1. Go to the directory nrf52832.
2. Change the SDK_ROOT variable to your path of nRF5 SDK in the Makefile.
3. Change SDA_GPIO and SCL_GPIO for your I2C pins in main.c. By default SDA_GPIO = 26 (P0.26) and SCL_GPIO = 27 (P0.27).
4. Run make flash to compile the code and flash in MCU.

The output to UART should be like:
