Hi,
Does anyone know of a chip that can read a number of parallel bits and transfer them serially?
I'm trying to detect the state of a number of mercury tilt-switches then send the data to the COM port. I suppose I could design it from scratch using gates but this would be silly if a chip with this capability already existed...

It's called a UART if you want to use the serial port. Or, you could use shift registers.

Much thanks & appreciation!

Using gates, the cost to you will be $5.
Use a PIC and the cost is $1-50.
Im not sure if you know already but if you use the parallel port (LPT1) you can read the mercury switches directly without adding extra ICs.
Yeah thanks but I'm lazy, I don't want to have to unplug my printer & scanner :-)
