RTC-DS3231 C++ PROGRAMMING HELP ON RPI 3

[Khalid]

Hi everyone,

Can anyone please help me in C++ code for RTC DS3231. I have the arduino code but I am struggling in changing the syntax on Raspberry pi as I am a beginner.

I am trying to create classes for writing time, alarms and set the square wave.

Thanks in advance.

For module setup try the following shell commands –
sudo apt-get update
sudo apt-get -y upgrade
Now modify a system file using :
sudo nano /etc/modules
If it isn’t already there add “rtc-ds1307” to the bottom so it looks something like :
snd-bcm2835
i2c-bcm2835
i2c-dev
rtc-ds1307

For I2C device –
sudo nano /etc/rc.local
Add the following two lines before the exit 0 line :
echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
hwclock -s
Then
sudo reboot
sudo raspi-config
Then add date –
sudo date -s "28 DECEMBER 2018 13:00:00"
sudo hwclock -w
sudo hwclock -r

Thats all
