Reverse bit order of a byte
On the upside, by the time Rev. M comes out it's only logical to conclude that 'MUL' (and 'MULS' it seems) will take 0 cycles, which means the routine from #68 would take 10...

Reverse bit order of a byte
Thank you for the spot.   Just checked it using AVR Studio's simulator and you're absolutely right.     I was going from page 125 of:   http://ww1.microchip....

Reverse bit order of a byte
Seems I can't let this go. My weekend Sudoku (amongst other things) is paying the price.   Just supposing a look-up table wasn't allowed and the following conditions could be...

Reverse bit order of a byte
Thought I'd have a look at this. Maybe it was the use of the word 'necromancy' which fondly reminded me of a radio show called ElvenQuest? I have spent far too much time on it and...

Alf-Egil Bogen on the beginnings of the AVR
During an early AVR workshop I heard a report of how your first meeting with the CEO of Atmel at the time (George P?) went. My memory isn't the best but I think it went along the...

ATmega-M1 and alternate SPI

ATmega-M1 and alternate SPI
I've just taken a look at the preliminary datasheet on Atmel's website. I'm 99.9% sure that ISP is performed on the MOSI_A, MISO_A and SCK_A pins (Table 27-15 on page 293 and...

AVR Serial programming? SPI?
Hi, I have used a mega8 to program a mega128 via ISP using the mega8's SPI port in mode 0. Try slowing the SCK frequency down to begin with. Hope this helps. Pete
