OBD-II STN1110 - QFN Problem
#10
Hvala za shemu, sad je malkice jasnije ...

Ocigledno imas neki problem na CAN strani.

Da li imas signale pre ulaza u MCP kada prozoves recimo 902 komandu?
Da li imas iste te logicke signale na izlazu iz MCP tj na CAN bus (diferencialni signal)?
Jel si gledao to sa osciloskopom?

Koliko shvatam MCP je samo interface, da li postoji neki loop-back test recimo kada se prespoji RX/TX na strani ulaza u MCP?

Cemu sluze R19, R20, C20 i C21? Kako si izabrao bas te vrednosti? Meni to lici kao vrlo "tesko" opterecenje na CAN bus?! Probaj da odkacis te komponente sa bus.
Da li je mozda potrebno tu neka terminacija za bus?

Izvnini na ovolikom broju pitanja, ne mogu drugacije da udjem u temu Smile
