A projection clock (also called ceiling clock) is an analogue or digital clock equipped with a projector that creates an enlarged image of the clock face or display on any surface usable as a projection screen, most often the ceiling. [1] The clock can be placed almost anywhere if only the projected image must be seen.
The mouse cursor was drawn on the screen by software, as were all other on-screen objects. To support real-time animation the screen timing PAL circuit would send a pulse to the 6522 once per vertical retrace. This was the basis for an operating system service called the VBL (vertical blanking) Manager. When the screen was to be redrawn, the ...

The app consists of a world clock, alarm, stopwatch, and timer.
The transmit clock signal is always provided by the MAC on the TXC line. The receive clock signal is always provided by the PHY on the RXC line. [citation needed] Source-synchronous clocking is used: the clock signal that is output (by either the PHY or the MAC) is synchronous with the data signals. This requires the PCB to be designed to add a ...
