Question about timer
Use 16MHz Crystal for maximum speed count. It is 16 bit. for expanding, append upper bytes in the interrupt overflow routine. before reading 16 bit counter register, check...

Desing a AVR based DC Power Supply(Thinking Stage!)
Quote:for the sake of discussions let us assume that a output range of 5v-30v is required(lets call it V_Desired), Current not exceding 1 Amp(Imax), Input voltage after...

Building a sine wave lookup table
using an active filter, its possible to convert Square to Sine wave. it means you have to only generate 1MHz 50% Square wave. Also, do visit http://www.priorartdatabase.com/IPCOM...

Desing a AVR based DC Power Supply(Thinking Stage!)
using non switch mode configurations (such as lm317), you will waste input power. by the way, Lm317 only work till 37 Volts ! Regards A.R.Khorasani http://www....

Is there any rule to change registers inside interrupts?
Try OCR1AH=OCR1Avalue>>8; OCR1AL=(unsigned char)OCR1Avalue; Regards A.R.Khorasani http://www.instrumentalanalysis.com

Building a sine wave lookup table
Hi, you receive sine wave after filtering the pwm square wave. as we see in http://www.atmel.com/dyn/resources/prod_documents/DOC2816.PDF also, - can define look up table in flash...
