[kvsa]

Hi, Mr.Venkadesh.M
Thanks for your reply,
Here with i attached the schematic


kindly reply

R3, R4, R7, R8 are not needed. R6 and R5 should be 300 Ohms. If RC4 and RC5 are input pins then R1 and R2 are not needed.

Hi kvsa you can continue in the same thread itself no need of posting a new thread.. and as jayanth.devarayanadurga said you have to modify the resistors....
The programming part is very simple and you can do whatever you want, I always use HiTech compiler so i am writing on it, you will need MPlab IDE and hitech compiler for compiling purposes..

Hi, I develop a small project Using Pic microcontroller 16F676 i need the 'C' code for that.

In my hardware Pic 16f676 is used
RC5 is Input 1
RC4 is Input 2
RC0 is Output 1
RC1 is Output 2
I used internal oscillator in Pic 16f676

Sequence
Initially some delay time to start this operation
RC5 gets a input signal, Output RC0 enable (some delay for holding)
Interlock between this two operation
RC4 gets a input signal, Output RC1 enable (some delay for holding)
This cycle is continuous operation

Can you help me to develop the 'C' Code this sequence
By kvs

And did you mean any one of the output shd be high as interlock???

if you are going to ucsp then connector also should be there to burn programm.

Hi mathe,
If once RC0 = 1 then how it will get turn off??
