Hi Jungs,
bin gerade dabei ein FM24C02 mit einem Pic24fj64ga004 anzusprechen.
Da meine Hardware noch nicht da ist simmuliere ich mit Proteus.
Nun kommt immer die Fehlermeldung
Master:attempt to initiate simultainious actions i2c2con
Wenn ich das ganze auf I2C1 umschreibe kommt die selbe Meldung nur dann
mit i2c1con
Was mache ich falsch ?
