I'm working on a chip to put on a one wire bus. My idea is to use a small pic12f chip.
What I'm thinking is this put id on these chips one or two to start and make them send data just like a DS one wire chip.
What I want is to use them to turn things on using one wire.
What I'm asking is this the right timing
1 the master sends a 480uS Low reset then waits for the slave.
2 the slave sends after the line goes high for about 15uS a 60 uS low to let the master know it's there.
3 the master sends a 15 uS pulse which the slave then leave the line high for a 1 or pulls low for a 0 for each bit it sends. At 60uS a pop.
Have I missed anything here thanks for any input. Burt
