Hi, I've strange problem with DS2780, single slave at network, master device is DS2480-100, RPI, owfs.
IC DS2780 at owfs startup is not detected (during RPI/owfs startup battery connected to DS2780 is NOT charged/discharged). To make DS2780 "visible" I'd to force host to "get some energy" from battery. After that DS2780 is working fine. I've done some research and found that problem is with tpdl time: On startup tpdl time is 49.6 us, which is a little to low get detected by DS2480 (min 66.5 us). After forcing battery to work (turning of external power) tpdl increases to 116.5 us and is working fine with 1 wire network. Does it sound familiar to someone? Looking for any help/suggestions. I know that it's probably not OWFS issue but maybe someone........
