(Little) Endianess Guide for Atmel AVR

Posted by coldtobi | 5 Jul, 2007, 16:59

As I frequently need that information, also frequently I forget it again. (Usually, the C-Compiler has to care about it, but if you have to take over e.g a serial line, you have to know it.

Atmel AVR Endianess Cheat Sheet:

Example Value: 0x0A0B

All 8-bt AVRs:   Little Endian     in Memory 0x0B 0x0A (*adr: 0x0B, *(adr+1): 0x0A)

AVR32:           Big Endian        in Memory 0x0A 0x0B

LittleEndian is popular at Intel CPUs,

Big Endianess e.g at Motorola.

Projekt: Lüfter/Pumpensteuerung für Wasserkühlung

Posted by coldtobi | 17 May, 2007, 10:23

Ich möchte für meine WaKü eine Lüfersteuerung basteln, da mir meine Pumpe bei 100% zu laut und die Steuerung auf dem Mainboard zu blöd ist.

Es soll ein "Projekt 2.0" werden, also ich möchte Ideen und Vorstellungen  anderer potentieller Nutzer einfliessen lassen.

Wenn es fertig ist, werde ich die Hardware/Software natürlich auch anderen zugänglich machen, aber jetzt ist erstmal muss man ein wenig ingenieuren...
