Wenn ich dran denke, welche Klimmzüge ich mit den RAMless AT90S1200, ATtiny12/15 gemacht habe, bekommen ich heute noch das kalte Grausen. Ich hatte sogar ein Pseudo-Call-Macro geschrieben, um den lächerlich kleinen Hardwarestack auszutricksen.
muss dann extra der komplette RAM (abzüglich Stack) frei gehalten werden? Eigentlich wäre ein AT90S1200 für Moby das geeignetste Bauteil gewesen. Wo kein RAM ist, kann man auch keinen verschwenden. :-)
Wer benutzt denn ernsthaft diese AT-Befehle? Das erinnert mich an meine Zyxel-Zeiten Anfang der 90er. Mit dem Arduino-IDE kann man bei dem kleinen Ding schon ganz schön was reissen und muss es nicht als seriellen WLAN-Adapter mißbrauchen

Hallo, ich habe folgenden Aufbau. AT90CAN64 tauscht mit ATtiny44A über I2C alle 100ms Daten aus. Um ATtiny44A programmieren zu können, muss ich die I2C Kommunikation von ATMEGA90CAN64 (I2C-Master) erst einmal z.B. durch Erase still legen
ATtiny44A schrotte? Wenn so, gibt es da eine Schutzschaltung dafür? Wieso passiert das nicht mit AT90CAN64? Gruss Stefan
