Title: lambda on a 16bit LoHi, 1 = 7FFF or 1 = 8000 ? Post by: elRey on January 22, 2013, 08:37:40 AM For lambda on a 16bit LoHi scale, does 1 = 7FFF or 1 = 8000 ?
I know on a 8bit scale 1 = 80 which leads me to believe 1 = 8000 on 16bit. Thanks, Rey Title: Re: lambda on a 16bit LoHi, 1 = 7FFF or 1 = 8000 ? Post by: phila_dot on January 22, 2013, 08:56:44 AM 1000h
7FFFh is max postive signed word and 8000h is max negative signed word. Title: Re: lambda on a 16bit LoHi, 1 = 7FFF or 1 = 8000 ? Post by: slowrider on January 22, 2013, 10:11:02 AM 0000h LoHi => 0
0100h LoHi => 1 0200h LoHi => 2 1000h LoHi => 16 Title: Re: lambda on a 16bit LoHi, 1 = 7FFF or 1 = 8000 ? Post by: nyet on January 22, 2013, 11:45:48 AM btw just a nitpick LoHi is immaterial in this discussion if you are expressing hex terms in short words and not bytes.
i.e. 0x1234 = 0x12 0x34 HiLo 0x1234 = 0x34 0x12 LoHi Both are 0x1234 :) When expressing values, they're always expressed big endian Title: Re: lambda on a 16bit LoHi, 1 = 7FFF or 1 = 8000 ? Post by: nyet on January 22, 2013, 11:48:14 AM 0000h LoHi => 0 0100h LoHi => 1 0200h LoHi => 2 1000h LoHi => 16 More properly: 01h 00h LoHi = 1 = 0001h 02h 00h LoHi = 2 = 0002h 10h 00h LoHi = 16 = 0010h |
