Orange pi plus 2

[Marcus81]

Ahojte vsetci,
viem ze toto je o raspberry debata ale mam doma orange pi plus 2 a chcem k tomu pripojit teplotny snima ds18b20 a uz fakt neviem ako. Na raspberry s tym problem nemam, funguju vsetky v pohode, ale tu mam problem so zapojenim. Presiel som na nete tolko stranok a kazdy tam pise o inom sposobe pripojenia, vsetky som vyskusal a stale nic.
Neviete mi s tym nejako pomoct.
Dakujem za kazdu odpoved.

Funguje bez problemu.
Jen je potreba mit zprovoznene wiring a pouzit spravne gpio piny. Jsou jinak nez na rpi.
pokud mas spravne wiring pro tvuj board, mel by ti pomoci prikaz gpio readall kterej ti ukaze kde kterej pin mas.

Aha, no nie som do toho az taky macher, ok. A mas nejake schcematicke zapojenie na ktorom ti to funguje? Skusil som ich uz kopec, jedine co mi vypise je w1_bus_master1. Podla prikazu gpio readall mam in na pine 37, to je pre DATA zo snimaca, tak som to mal a len toto mi vypisuje a nevidi ho.

Toto vypisuje gpio readall:
