lang=EN-CA>spolehlive reseni je standardne jedno: zapojit rizeni RS485
interface do MCU, na kterem je UART od tohoto kanalu. A ridit smer interface
pomoci programu, ktery vysila a prijima. Je to treba udelat dobre, tj. pres
preruseni a dobre si uvedomit, ve kterou chvili ma ono preruseni nastat ->
po skonceni stopbitu (od posledniho vysilaneho znaku). Vsechny ostatni reseni
s SW/HW MKO jsou obvykle o level nize, pokud se tedy neuzije technologie
F&S, ktera prijima a vysila cely ramec a rizeni linky je ovladano zpusobem
uvednym vyse. JM<o:p></o:p></SPAN></P>

vsude spousta, ale velice narychlo bych potreboval pro jednu aplikace ktera s
tim nepocita dobastlit komunikaci dvou zarizeni RS485(Raspberry a PICAXE).
Proto hledam nejake opravdu spolehlive overene schema toho automatickeho
prepinani smeru. Nasel jsem treba tohle <A

ale v diskuzi to nekteri moc nechvali. Bohuzel cas nas tlaci a nemuzeme
testovat ruzne varianty. Mate nekdo nejake jednoduche a spolehlive
zapojeni(schema) na prepinani smeru 485ek. Par schemat jsem nasel, ale jak
rikam cas na testovani moc neni... Klidne pustime i korunku za nejake omercni
KnowHow, bo to je akutni...</SPAN><o:p></o:p></P></DIV>
