RE: [Owfs-developers] speed of the serial port
I'll need to check. Type, present, ... don't require getting data from the chip (except it's address).

RE: [Owfs-developers] w1 changes
Jan, the only support needed would be either a sample of the hardware (adapter) or the willingness to test frequent test builds. The only changes will be that the w1 polls at it's own rate rather than on demand, and that multiple adapters aren't yet supported by w1. Also the alarm directory isn't yet implemented. Evgeniy is eager to improve function.

I will definately build a board based on the DS2482-800 chip and will test owfs improvements, too. The only changes will be that the w1 polls at it's own rate rather than on demand, Hm. That's not so good. If one has a lot of chips on the bus, but only a few of them used at the same time, synchronous polling makes thing things damn slow. But that's exactly my use case. I could release a developer for this in ~8..10 weeks I think, but that's too late for my current development. Maybe the best idea for me is to put space for both DS2480B and DS2482-800 on my PCB and improve later. ^^; and that multiple adapters aren't yet supported by w1. Not that important for me, I think. Also the alarm directory isn't yet implemented. Evgeniy is eager to improve function. I'll talk to him directly, too.
