Hi,

I'm posted (answered) a lot in an other topic (in "PIC Basic Languages", under topic "Moving Message Display") and I'm attached here my last projects in this thema. There are two ZIP attachments from me ...

This thema is preferably good here (included sources in assembly and working DSNs).

If interested... please look at and post me your opinions here!

Hi,
I moved (attached here) my projects and deleted from the topic above.
Assembly sources are included.

And a bonus (offtopic a little, sorry):

I wrote a full animated crossing simulation (also attached) in Proteus:
It is using 4 LCDs, 4 traffic lights and a PIC16F84 (assembly source included too).

Hi 'sos',

I'm attached two zips here but you cannot to see beacuse you don't have posts enough yet. You must have min. 25 posts to get a status "Junior member". After this you can see and download the attachments in posts and can to search here in Sonsivri.

However, I post now a PM to your email address with my projects as attachments.
Please read carefully the original article from ELEKTOR (included in PDF form in the first zip).
Hope this helps for begin.

Do you have a Proteus v7x installed? If not, you can it download from Sonsivri too.
I'm working with it only. I recommend the v7.1 sp2...
The AT89C2051 what I'm using is 8051 compatible.

Hi,
Is it possible to store data in serial eprom and 8051 read data to be displayed from serial eprom so that if power fails data can be restored from eprom
Thanks

Hi;
Yes, it's possible but not so easy, needed be more programming and hw ports. There are a lot of SPI controlled serial eproms and code examples how to use it ...

Why do not use an other uC (for example a PIC16F628A) with embedded EEPROM?

Take a look to my new thread on this thema:

Dear Sir Zuisti,

I see your both projects. Boths are very nice but crossing project is really great project & use new use of LCD. Another thing is program is working with pic16f84, only 357 program words are using.

Very nice ASM Code, specially useful to learn new programming skills.

Regards

Roshan
