please kick start me :-) - Electronic Circuits Projects Diagrams Free

I've just received my very own PicKit 2 programmer and am dying to see something working. so lets say flashing leds just to be original lol
can somebody post or link me to the program needed and the circuit diagram I intend using the 16F88, does the pic have to be totally isolated from the circuit when programed ?

Hi,
I just got mine too 1 month + ago.
Just check the datasheet of PICKit2 from Microchip's website. The connections of ICSP is in it. For the program, as usual

yea I saw nigels tutorial and think I might try following it through but I only have 16F88 and 18F1220 and 18F1230 pics so was wondering if the programs will run ok on the 16F88

bananasiong · 18th January 2008, 03:20 PM

Of course it is working, but you need to do some modification.
Since PIC16F88 is full of features, one configuration setting is not enough

, remember to have two configuration for that.
Besides the comparator, it has built in ADC as well. By default, some pins are analog input pins, so you have to make them to be digital I/O first before doing any digital controlling.

ok perhaps I just make myself a new email address and get some more samples orders off right now as I've already ordered the above pics for the next 35 odd days

Go to Wouter's "Blink an LED" site. Quick and easy hex files for many PICs, with circuit diagrams.

The source code is in JAL language though. It's a decent language (a little like Pascal), but not officially supported by MPLAB. Hmm... I wonder if I could integrate it... Aha! There's tonight's project.

No, you shouldn't do that.
PIC16F88 is the most powerful 18 pins PIC among the 16F (for me). Just stick with what you have.

Thunderchild · 18th January 2008, 03:50 PM

erm yes but I know nothing about programing and need tgo start simple then move on
suppose nigel used what he did for a good reason

The other PICs are no more "simple" than the F88. Every model has its own differences you'll need to learn.

bananasiong · 18th January 2008, 04:01 PM

Ok, here you go:
Instead of

Code:

	__config	0xxxxx

	movlw	0x07
	movwf	CMCON

Use

Code:

	__config	_CONFIG1,	0xxxxx
	__config	_CONFIG2,	0xxxxx


	bsf	STATUS,	RP0	;to select bank1
	clrf	ANSEL		;disable the analog inputs
	movlw	0x07
	movwf	CMCON


	bcf	STATUS,	RP0	;select bank0

The xxxx you have to find out yourself from the datasheet.
The rest of them should be the same.

It was to avoid confusion, and the complications of extra facilities - the 16F88 is fine to use, and only very small changes are required.

Thunderchild · 18th January 2008, 04:57 PM

ok so are the edits bananasiong posted suitable the xxxxx what is that that I am looking for ?

Looks like it (on a quick glance), obviously you need to fill the x's with the config settings you want.

Thunderchild · 18th January 2008, 06:10 PM

ok by xxxxx that I want what is actually meant ? does this set the pic functions so what functions do I want ? (obviously not ADC)

Thunderchild · 18th January 2008, 07:24 PM

so I'm making a sample order of 16F628A what else could I get while I'm ordering ?
