QUOTE The term "engineer" may also be used to describe holders of some forms of professional certification other than university degrees, such as (but not limited to) Microsoft Certified Systems Engineer, Certified Novell Engineer, Red Hat Certified Engineer and so on. In Canada, the usage of the term "engineer" to describe holders of professional certification is not legally permitted. The Canadian Council of Professional Engineers mounted an extended campaign to get Microsoft to renounce use of the word "engineer" in the title of their certification. A 2001 reader survey by Microsoft Certified Professional magazine found that over half of respondents supported changing the name of the MCSE to remove the word "engineer". I'm a electrical engineering graduate majoring in information systems, currently working in a telco  . I know this is a bit out of topic but I really feel upset when Computer science or IT students address themselves as IT engineer, Software engineer, etc, etc.  The above is qouted from Wikipedia. |

QUOTE(charge-n-go @ Nov 21 2006, 05:27 PM) this is still much better than a technician calling themselves as support-engineer This is a new one. Usually I'll just address them as tech. Sometimes it's the company's which name the positions rather than they themselves who wants to be addressed that way. |

QUOTE(lgh @ Nov 21 2006, 05:34 PM) why do you wanna get upset with that ? Do you think sales engineer are really engineers ? It's just a name, just be happy with what you know, not what people are addressing you as . To me, I've put my best effort to understand my studies and work. I regard engineering as a profession. |

ASIC is way out of my league, my hobby is to program MicroC from Microchip. Now I'm working on Radio Network Servers.
For FPGA, I did a bit of VHDL during Logic lectures hahahahha |

Usually I use 16F877A for PWM and ADC. If those are not required, then I'll go for 16F84A. Haven't tried 18F though

QUOTE(lgh @ Nov 21 2006, 05:59 PM) These are so called PIC microcontrollers rite ? I used to learn how to program these chips in the Uni long time ago by writing chip instruction specific assembly code. fun stuff. Yeah, its PIC's microcontrollers Now dealing with a lot of 32 bit processors like powerpc , ARM. As microblaze(xilinx) and NIOS(altera) seems to be getting more and more acceptable in the market , there's a plan to actually put all these softcore processors into the FPGA !!!! more work ! The good thing abt softcore processor is that it's just so flexible. i can hook up anything i want thru the peripheral bus. i can even include or exclude a simple FPU. there is a C compiler for it but then I still prefer assembly.I was involve in Robocon, so microcontroller programming is essential. |

QUOTE(charge-n-go @ Nov 21 2006, 06:15 PM) Sorry just now forgot to ask something It depends on the input clock also. For example, the input clock is 20Mhz. A PWM 8-bit registry specifies the percentage of the input clock to the PWM generated. If you put 00000000 to the registry, means the PWM will be 0Hz, if you put 11111111 to the registry, the PWM will be 20Mhz, if you put 10000000, the PWM will be 128/255*20MHz. Hope that you get what I mean.How u use these chips to control the pulse width in general. I mean, u setup the intervals or taking in some inputs and automatically generate the output based on an algorithm? |

QUOTE(charge-n-go @ Nov 21 2006, 06:33 PM) Yup, understand some PWM controller can control the On and Off rather than it has to be equal, for example:-thanks ! Actually i suck in electrical stuff, hope you can explain a lil more on PWM. How can we determine the output quality of a PWM controller? Does higher clock result in better output waveform? I heard that some PWM controller are better than another, what aspects they are comparing to identify PWM A > PWM B? _ _ _| |_| |_ equal __ __ _| |__| |_ equal _____ ____ _| |_| |_ not equal |

it cant be shown properly after posting, to put it in words, some can control the length of 5V and 0V rather than making it the same.
