Hi, I have a cobbled-together DS2480B-based one-wire master that I want to use for experimenting with a long one-wire bus.
I've been tweaking owfs (2.8p17) to add pulldown slewrate etc. control for a serial bus (am I correct in thinking this is not yet supported?). I've managed to add the beginnings of the device specific code to ow_ds9097U.c (in owlib/), and the fuse hooks into ow_interface.c (using the equivalent usb-specific code as a template, especially for fuse). I can see that the initial device reset calls my bus_timings() function in ow_ds9097U.c, and that if I write to bus.0/interface/settings/serial/pulldownslewrate, the value is successfully stored. I was hoping that a fuse update would automagically trigger a device reset to update the device, but that does not seem to be happening. Looking at the ow_interface.c/ow_write.c code, I don't see any explicit reset calls, but presumably they're happening for usb devices (i.e. a write to bus.0/interface/settings/usb/pulldownslewrate will trigger a reset of the device). Any pointers on how I could get this working for a serial-based device? Thanks, manuel. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
