Simple Clockable Decoder Chip
Tom�s � h�ilidhe wrote: Only one pin is needed from the microcontroller. With the shift register setup, two pins are needed (one for clock, one for data input). You can make a vanilla OneWire Shift-Register interface, by using a RC on the Data pin, and pulse-width varying the clock. Assuming a P... 7 May 2008 00:21

Loss of synchronisation: Are the chips reliable?
Tom�s � h�ilidhe wrote: The PC I'm typing on right now is perfect. Most certainly not. It's working exactly as intended. When I press "e", an "e" appears on the screen.

AC spike go pass XFRM and regulator to reset CPU!!??
Hi all, I have a device that is powered by 240VAC (also works from 120VAC). The AC drives the primary of a transformer (with a fuse and a MOV). There is also a fan connected to the 240VAC with a switch. The secondary of the transformer has a bridge, a large electrolytic cap (1000uF/25v) and an LM7805 regulator... 24 Apr 2008 23:48
