Hello all experts and everyone else.
I need advice on a experiment i want to do.
Its using a simple a/d 8 bit converter (adding a addressing sequencer for eeprom addressing) then memorizing /saving it in to eeprom and then later outputting data thru d/a .

For an idea, check out www.romanblack.com and look at his sound encoding pages.

Thanks muskrat
very good site but the problem is the hassele of pic programming i would like to avoid.
all that upload download pickit this and that needing to understand pic programming.
now they show me the hex file not so sure what i should do with that and how to copy it into the pic.
i dislike programming lets make it pure electronics.

I once thought the same until, with help from the CZ I started looking at the PIC range and learnt about them.
I have a huge amount of control gear on the farm. To have built it all using dicrete devices would have resulted in cumbersome, fault-prone instruments. Pics have resulted in small, versatile devices. If the functionality needs changing, or a better way of doing the task becomes evident, it's easy to change by re-programming a PIC.
A simple, low-cost programmer - I use the PICKit 2 - a handfulu of chips to play with and a whole new world opens up.
I would strongly recommend that you have a closer look at these chips, they are amazingly versatile and reliable and above all, fun!

I have learnt the basics of assembly programming for the simpler tasks I want to do. If I need something more complex, I search the web or ask for help, at least until my expertise improves. I am currently looking at MikroBasic.
PicKit 2 programmer is a great little tool and handles most of the PICs you would use. Initially I built my own programmer which was interesting and taught me a lot.
As far as the HUGE numbers of PICs available - I use 16F88, 16F628A, 16F648A, 16F876A and the 16F877A.
With the jobs I have to do on the farm, these are really all I need.

Do you mean the PIC16F876 or PIC16F876A?

However, I would say it supports both.

According to the advert, it supports the 16F976A and devices that MPLAB supports.

MPLAB supports the ICD2 and both the 876 and 876A

Regards,
Joe
