Re: dV/dt triggering of a SCR(Thyristor)

Thanks ZevenZero.. I understood it simply according to your answer.But,This has big theory behind. Equation manipulation is not clear.It's my problem,I dont know calculus :( I must learn it. dV/dt triggering is clear. :) you mean this, >> ic = d(CV) / dt = C. dV/dt + V. dC/dt it's simple product ru...

Re: help on simple pic 12c508a project

I reviewed your code. I think lines bellow are syntactically flawed. Check and review those lines back. you are talking about the toggle led GP0 or GP1. see these lines. I think you are messing up with GP1 and GP0 , what actually the toggle LED is connected? xorlw b'001010'; activate bit GP1 (out of...

Re: GSM/GPS Location detect project

>> Can I program Atmega328 Using Micro c? Don't know about Micro C. How about code::blocks if you really required a IDE? Code::blocks does have usbasp tool but I've checked it does not work. So then you did need eXtreme burner like software, and manually set fuses there. You need usb asp if you prog...

Re: GSM/GPS Location detect project

Lasantha , you are describing a 'daughter board' something like this: http://www.mouser.com/new/microchip/microchipAC32001/ They were used on those cheap sensor networks. I'm not sure that you would need something like to design your own hardware? Then a FPGA daughter area is preferred. I think ther...

Re: GSM/GPS Location detect project

As neo told above Dalvik VM does provide good interface to access GPS. Even that is the normally used method when they do this on RPI like board too. Read his instructions. You could ask code examples on android section. >> Phone eke hardware architecture ??? ??? ???????? ??????? ?????? Why not? It'...

Understanding the theory and appliations on filters

Hi I'm studying some engineering mathematical concept called 'pole-zero plot' diagrams and I'm so confused with the theories behind those. Could somebody suggest me a good book and also some examples [how to describe filters ] using such mathematical tools. I'm reading a AnalogDevices analog dialog ...

Re: Create Pin array in HI TECH C

>> Also, I'm wondering why you need such as array to assign to the port. As far as I see it, your purpose is to avoid nested ifs and use the port as a lookup table. I think he need to use that array in a for loop. If so use that index method provided by neo. as said , you could not create arrays of ...
