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

Thanks SemiconductorCat,

This system (dV/dt triggring) has semiconductor level explanation.I have an idea about this capacitor/capacitance which generated J2 junction.
I think,I have small idea about semiconductor level explanation.

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. :)

dV/dt triggering of a SCR(Thyristor)

Hello Friends, Following quote is copied from Wikipedia(Link: http://en.wikipedia.org/wiki/Silicon-controlled_rectifier ) I have learned something about SCR(Thyristor).In normally we can apply gate threshold current(=Latching current) to turn on the SCR. In following statement says dV/dt method for ...

Re: Create Pin array in HI TECH C

PORTB = (PORTB & ~(1 << index)) | (value << index); return ((PORTB >> index) & 1); Nice cording Neo... :biggrin: I got some time to understand it. Thanks.. SemiconductorCat, Your coding is hard.I cant understand. because,I couldn't study about some part of your code..Soon I will understand it. :)

Create Pin array in HI TECH C

Hello Friends, I want to create pin array in HI TECH C for PIC16F like Arduino. int ledPins[] = {2, 7, 4, 6, 5, 3 }; Assume I have PORTB.RB0,RB1....RB7 are my pins now. I coded like this, #define D0 RB0 #define D1 RB1 #define D2 RB2 #define D3 RB3 #define D4 RB4 #define D5 RB5 #define D6 RB6 #define...

Re: How to handling interrupting PIC 16F877A

Really good post. :biggrin: Thank you. I like to add more useful things to your small sample program according to my knowledge. In this ISR waiting for only RB0 interrupts for Toggle PORTC LEDs. Some time another interrupts can occur .Because Global interrupts are enable.(GIE=1)Therefore,In ISR must...

Re: Run a Loop for specific time in HI-TECH C

Thank Neo and Semi,
I can understand your explanation Neo.I know something about thread,CPU cores...
Thanks for Semi for example code.

Re: Run a Loop for specific time in HI-TECH C

Thanks Neo,
Timers is good way.But,I have only one timer for all. :?: :?: :?:
Can't we do this using Delay loop?

Can I handle some thread?Like Java or .NET? :x

Re: HI-TECH C "can't generate code for this expression" Error.

Thanks Semi...,
Ellipsis is very nice point.
I don't know sound knowledge about PIC stakes. :(
I must learn it.

Thanks for helping
