Advice on how to use a PIC. To Control a Calender Dial
Hello everyone.
I am seeking advice on a little project I have in mind.I may find it a little hard to explain due to my lack of knowledge with PIC's but I will try my best.
The project I have in mind is to build a Mechanical and PIC.controlled calender clock/dial.
The calender clock dial will be run mostly from an Electro Mechanical impulsed movement that has a 31 toothed wheel (for max 31 days in a month)the movement is Electronically impulsed once every 24 hours so it is easy to get the calender dial to indicate the days up to 31.The hard bit is when the days of the month go to 28 or 30 now the wheel count can't do this.
My Idea was to have a PIC follow the natural flow of the electro movement and add on extra impulse only where required.
The chart in the attached file shows the months and the 1's are for the impulses required each day( 24 hrs) The red 1's show where the PIC will have to add a pulse so the count always adds to 31.(I hope you can read the file,I will email you it if you can't)
I think because the Calender clock receives an impulse to work the electro magnets that move the 31 toothed wheel a PIC. should be able to follow this pattern and could make adjustments where required.
I hope someone can help with this one.I have just picked up a Pic training course and hope to trial this project.
Regards Mark.
