8 pin PIC12F Clock [ DS1307 + I2C LCD ]

[milan.rajik]

Here is my 8 pin PIC12F clock. Still 70% of ROM is free. Will try to add more features. Will soon add a I2C temperature sensor and many more I2C devices and make a feature rich device.

Will try to make another clock with DS3231 which is a better RTC.

I think a Waveshare AD Keypad will be better. It needs one ADC pin to interface 4X4 keypad for RTC setting and LCD navigation. A MCP9808 will all do.

Just providing links for I2C LCDs. So that one can use them with my I2C LCD Code.

One can buy these I2C LCDs or the I2C LCD module. I have them and they work fine.
