Folosesc de ceva timp un Beaglebone white pentru achizitia unor informatii de prin casa, in special de temperatura. Senzorii sunt toti pe magistrala 1-Wire. Magistrala are cam 25 m . In beaglebone se foloseste driverul w1_gpio compilat in kernel . Acum vreau sa mai integrez in retea si niste module de executie. Am luat cateva DS2413 care sunt de pricipiu doi biti I/O pe un chip. Problema ca acestea nu au modul de kernel printre cele existente in sistem . Nu gasesc modulul w1-ds2413.ko compilat pe kernelul respectiv ca sa-l pot instala si ar trebui compilat. O compilare pe beaglebone cred ca iese din discutie asa ca ar trebui un cross compile . Treaba asta ma depaseste . Ma poate ajuta cineva ?
