    procedure to keep good sized drill hole into Orcad 10

    Sorry dude, I has been years that I haven't touch a Gerbtool... I'll check this out at work if I could found an old tool... But I could guaranty.

    cadence PSD and Allegro, what are the difference?

    But does Design entry CIS ported on Linux with the SPB suite ? (Design Entry CIs is formerly known as Capture CIS) Or does the only schematic capture software still is design Entry HDL ? (design entry HDL is formerly known as Concept HDL)

    Help me with delaying a clock in simple SPI interface

    Simple SPI Interface That is what I've... uuhhh.... I redone It myself.... I will put my works here as soon as possible

    prove of sin(a+b)= sin(a).cos(b) + sin(b).cos(a)

    you can use euler theory I think... with the exp notation... edit : sorry I didn't saw the euler PS...

    What's the function of a decoupling capacitor?

    decoupling capacitor Putting a capacitor (few nF) with low value is often used to filter the power of the IC (avoid glitches). Putting a high value capacitor (few µF) is locally used to make an energy tank... When the IC is running and has to sink a lot of current in a short period of time, it...

    How to transform capacity (F) to Voltage (V)?

    howto humidity c. dVc i=-------- dt where i is the current that pass through the capacitor, C is the value of the capacitor, Vc is the voltage at the capacitor's pads. Where U use the current Law, you will find a differential equation that you can solve...

    Simulation for Static performance of the DAC/ADC

    Though I had well read your message that talks about DAC, here is a doc that explain how to test an ADC... Let's assume that parameters are quite the same... nevertheless, I think that methods are similar bye

    which is better AVR or PIC microcontrollers

    ARM is better than MSP430... for big design but AVR are my prefered for small design

    HELP, programming MCU AT90S8535

    For what you want to do, try to start from an example provide with WINAVR... FYI : C has not been created for embedded development... Thus every compiler that are C compliant has to deal with embedded particular requierment as, put code into certain part of memory, interrupt and so on... It is...

    HELP, programming MCU AT90S8535

    yes of course : Sourceforge page : https://sourceforge.net/projects/winavr Direct link to mirrors : https://prdownloads.sourceforge.net/winavr/WinAVR-20040720-install.exe?download BTW you should go and read some articles in https://www.avrfreaks.net (it is where I found all I need for AVR stuff)

    HELP, programming MCU AT90S8535

    Well... don't see makefile.... try to use a more recent WINAVR (20040720) But I just poke at your code and saw __flash instruction or __interrupt or something else... In fact, you should take a look at the WINAVR manual and avr-libc which provides functions and macros to do what you want...
