6 hours work! now the time is showing.

at first, there is no 00:00 pattern- the display RAM is only refreshed when the time changes. it would be possible easily to start with 00:00 pattern.

the lines are shown 100 times a second, each. it is X-direction display, which is sort of unusual. normally you would think, the lines go from top to down, but they go from left to right, 4 phases.

there are 1370 words used from 4096, many of them for japanese days and months. there is no code to display on LCD, to set time, etc.
means, it must be added...

it is PIC16F913 microcontroller, speed is 8MHz.
