Hi guys ...can anybody help me with a development board (schematic ) with LCD and LED-s and some code examples for it , i want to use it with pic16f84 especially .
thanks,kta
The 16F84 is all but obsolete, target an up to date device, perhaps the 16F88 or larger, or better, start out with an 18F device.
There are loads of schematics for PIC development boards free on the net...google is your friend...
I would recommend using the Junebug from Bill at Blue Room Electronics, you can buy it in kit form or ready built and would be a much better starting point for you.
Yeah, I agree with tunedwolf - The Junebug is pretty much all you would need as it has a 18F1320 (correct me if im wrong) that you can muck around with using the LED's, etc.
Otherwise Developement boards are quite expensive from Ebay..
Thanks for the recommendations, the Firefly includes a 16F88 a nice chip but in my books the 18F1320 on the Junebug is easier to use and great language support.
You could wire up a 16F84 as it was the 16F88 if that's all that's available in your region. No Debug support, A/D or USART in the 16F84 though.

It was replaced last century by the 16F628, but appears to have been re-released at a highly inflated price for all the people who seem to want to use this long obselete device.
the only advantage i see for the 84a is the lack of ADCs/Comparators you need to disable in order to use a port for simple I/O.
and also the small register set.
i still wouldnt say it was worth it up against the likes of the 628 or 88.
I agree with Nigel here, they are selling them at 400% the original street price, amazing! For more or less nothing, they are really outdated an other wise useless.
I remember using F84s in the day for data stream logging and such. More or less everything at that time was a OTP 509 or F84. I also remember using the UV erasable 509 version(exact number escapes my memory). Man EEPs really did change the world. I remember waiting, tapping fingers for the cycle(s) to complete...
