My final year project at university is designing and building a user interface for a plug in electronic timer that will switch on an external load at a set time and switch it off again at a set time.

I am using a 6808 processor and a 2x8 alphanumeric lcd display. I have 4 I/Ps, 2 of which are for a rotary encoder. I only know very basic C.

Would anyone be able to help with the program or provide some links to good example programs? Especially for a program which would run and display a real time clock on an lcd display? Thanks
