beantwortet, nochmal: Nein. Aquafreund schrieb im Beitrag #2753200: > Dann fängst Du in einem AVR Forum auch noch über PIC Controller nach. Welcher AVR mit SPI und I²C wäre der preiswerteste? Eine Grundsatzdiskussion möchte ich in diesem Thread vermeiden. Mir ist es im Grunde egal. ^^ Falls

DDR_SPI in the examples must be replaced by the actual Data Direction Register controlling the SPI pins. DD_MOSI, DD_MISO and DD_SCK must be replaced by the actual data direction bits for these pins. E.g. if MOSI is placed on pin PB5, replace DD_MOSI with DDB5 and DDR_SPI with DDRB. 139 7707F–AVR–11/10 Assembly

Lisagou-Figuren, ohne das ich das jetzt richtig verstanden habe. Demo https://www.youtube.com/watch?v=ItjDd4kSHJc Paper http://www.eurasip.org/Proceedings/Eusipco/Eusipco2015/papers/1570093445.pdf Sieht eigentlich ganz okay aus, jedoch immer noch Rechnerei. 4. Idee: Sinusfrequenz mit Bandpass filtern
Frquenzmessung kannste ja schonmal so machen: http://www.fritzler-avr.de/HP/netzfreq.php oder mit einem internen 32Bit Zähler im µC. Phasenlage vergleichste dann mit einem internen 50Hz Signal.

Stelle. Lab funktioniert einwandfrei, lediglich nur auf meinem XP Rechner. Unter Vista Business SP2 32Bit mit AVR 4.18 wird alles auch richtig erkannt sogar programierung und veriefy (Avr Studion meldet ...OK). Das was aber wirklich am Controller ankommt ist fussel, mehrmals länger als ursprunglicher
