Hi

Hi everybody

Thank you all so much...

I'll start building the circuit now..
I'm really glad there's this site to help me..
God bless everyone

Jaseslin,
As promised in the reply to your PM, here is the Vdd, Vss connection diagram

Jaseslin,
As I said in my PM, I only have a old version of Electronics Workbench and it cannot open your file.

Does anyone know how to solve this please?

The file is a layout of the circuit I posted above on May 15 - Pulse Generator1.png

Hi Len

Hi Len

here u r..
sorry for keeping u so long

Jaseslin,
As I said in the PM, here is the circuit I am using. Your voltage measurements do not reconcile with the pin numbers shown in this diagram which is based on the bit map you posted on May 22 as pulse_generator_1.bmp.

hi Len
sorry for the trouble..
I changed the pin connection so i can arranged the connection more nicely..
the one with the red circle is changed while the one that don is maintain.

Thank you

Jaseslin,
I have altered the drawing to reflect the voltages you measured (as posted on 24 May).

may i know wat's is still wrong with the ckt?

thank you...

really desperate,

Why don't you get another circuit from a different place try these

Jaseslin,
Your photo shows that you have made some errors in the wiring. So I have altered the circuit to show the differences in green.

Differences in pins numbers (compared to what I posted last time based on my understanding of your earlier post) won't matter but the errors will.

Note there is an error in the diagram, I should have written G1/1 not G3/1.
