(I use LED display screen for welding a lattice)
(and then want to use a variety of electronic components, welding a clock circuit, destroy cycle control display of the LED light, bright, to show that points, seconds, the display effect,)
I know there is the clock integration module, but really don't want to use the module,
Have a great god taught a thing or two, what creative circuit can achieve such effect,
Power source is dc DC12V, LED lamp is 3 mm leds, LED dot matrix display screen is Yin and anode are all separate out,
(the following is the clock circuit, recently in thinking about the how to do it,)

Recommended dedicated clock IC, then read need to display the contents of the MCU, LED display to you between "section of the code" can, does not need complex programming, simple operation, otherwise, such as the manager doesn't matter is very simple, because of the accuracy, leap year leap month,
