how to calculate in assembler?
Why not count for 200ms ? To MUL whth 0.9 (or the same result) is easy MUL with 256*0.9 app. 230 and then add 0.5 for rounding (128) use only the high byte. test: 30 * 230 +128 =...

better way possible? (code structure)
I know the problem but if the range is 0 to 127 it works fine. And if the function is to call H0 64 times then call H1 64 times over and over again the skip way works fine you...

input feedback problem. Need an expert please.
What is the V to ground when the AVR works but the read out is 0 RPM. Depending of how the tach works you may need a pullup to 12V. Or try to use the 12V as the reference point to...

How to implement software reset??
First with normal use of the reset an outputpin can be used. But normaly a CLI, stop timeres, set I/O to input etc, and then jmp to 0 will normaly but close enough to a reset.

Serial data transfer PC to AVR
I like to use Delphi (you can download a free version) and then APRO (free download) and with that you have a very good tool.

playing with GPS
Buy streets & trips with a GPS (on sale $99). It's has USB out, but the reviever it self is a 5V TTL signal out just wat you want for your AVR. NMEA 183 is 4800 BAUD, so for...

better way possible? (code structure)
Sorry an error read this (inc blockCnt) SBRC blockCnt,6 RCALL H0 SBRS blockCnt,6 RCALL H1

better way possible? (code structure)
I guess thai blockCnt is a upcounter, so if the line before the showed code is inc blockCount you can check on bit 6 high or not and the code will then be (inc blockCnt) SBRC...

Do you need a free tool and don't need to use C# , you can download a free delphi (I think think ver 6 is free now, for a long time I used a delphi 4 that came on a 'Alt om data'...

AVR and Overclocking
The first thing to fail will be writing to the eeprom. And don't program at high speed (part of the same problem).
