After a lot of research I came up building my own RTC using DS1307.
I will be using my RTC with Raspberry Pi.
I would have purchased a module but that was way too costly..so I decided to build my own.
Lets get started.
Step 1: Parts List
I usually shop for parts from http://electroncomponents.com
- DS1307 ( I ordered one but actually got a chinese VS1307N, but config is the same)
- 8 Pin IC Socket
- Coin cell Battery Holder.
- 3v Maxel Coin cell battery
- 32.768kHz Crystal
- 4 PIN Header
- 2nos 1K Resistor
Step 2: Schematics and PCB
Step 3: Putting It All Together
I used a prefboard to put everything together.
And this is what I have.
Step 4: Setting Up on Raspberry Pi
I use Occidentials v0.2 on my Pi. It has HW SPI enabled.
I followed the instructions from http://www.abelectronics.co.uk/rtcpi-raspberrypi-t... to setup my pi and here its works great. Though had some issues, rebooted after making every change to config files.
Incase you need any help do let me know and I'll be glad to help you out to my best.
Thanks for reading.
