Hi everyone,

Just wondering if anyone knows if there would be any limitations to
attempting to get a DS2406 to output bytes (words) at a time instead of
bits?

The idea is to get a DS2406 to output a IR code in a serial fasion, and
its output then go through a 38/40KHz carrier signal to pulse a IR Tx led.

ie: a 1-Wire Infra-Red Transmitter, perfect for remote control of air
conditioners with IR remote controls.

I know it could be done with PIC's, but would be nice to have a very
simple Tx circuit for the DS2406.

They have 1024 bits of EPROM but no RAM, so data would have to be
transmited over the 1wire bus in real time I would presume, can the 1w bus
send whole words at a time instead of just bit after bit after bit?

Could another 1w EEPROM (like the DS2431 1024-bit EEPROM) be used to store
the bytes then push it all as one word to a DS2406 (or something like
that)? ..or is that getting too close to a PIC setup anyway and might as
well go PIC anyway?

Any ideas?


Cheers,

Rohan.
