Debounce circuit is working fine .....

OK, leave it i will try my self
or use it as it is...

Then what should i do, of 8085 project...............??

Hello,

I am new to up's world as i have recently completed my EEPROM programmer...
now i want to use my 8085 uP, starting with some blinking LED's projects.

I know this forum is for 6502 up's but i have no option where to start this, I hope here i will get some help in 8085..!!

Thanks

and you have any idea of 8085 SBC hardware??

Sorry, for not getting you exactly.

My counters are working correct but while using these push on/off buttons it count in one direction and other direction count 1 to 2 bits not exactly in order...

pulse _ _Vcc
C up _ _ Count down
_ _
Vcc pulse


_ _ are the terminal of double pole push switches ...

No, you can see it data sheet it is very simple...

Hello,

After spending so much time I came to know there is some contacting problem arsing between these push buttons.....
when i pull them up the counters move in up ward address, while pushing down they don't count.

i have checked my circuit there is no problem in it, but there is some problem in ...

The circuit is being very complex now. because adding so many chip's and i will cure it the counter in series are not working properly

Here are some pics of my EEPROM programmers......

I have computer i3 .........and other device in it

What is this bootstrap??

The 2864 is working quiet well i have tested it with my counters and the chip is storing data also....!!
and i want to know is there any limit of time in whichthe write pin should be triggers?? as in data sheet it is mention for nana sec. but here i am using it foe sec......So, please clear this ...

OK, today i have implemented the denounce circuit using NAND gate....
it is working well and i have also cascade the 1983 chip but when taking out the carry to the input of counter of 2nd 193 chip it has 1 on its output .....
so when it start add. the 2nd chip shows 1 which should be 0.

I think i ...
