Hi all,

there are often questions about how to program, e.g. using RTOS or not, using C or not. Also it seems, some people have absolutely no idea, how to start to write a program.

Following an example, which use the simple main loop approach.
It contain also routines which are very often asked for:
- keyboard input,
- display output,
- clock,
- thermometer,
- PWM output,
and furthermore:
- Dallas 1-wire device functions
- DCF77 decoder

Its a radio controlled alarm clock with thermometer function including minimum, maximum storage.
Its fully readymade and fits into the popular AT89C2051.

Please look at:

I'm also very interest on any opinions about this example.
All my other applications are build in a similiar way.
