As far as I know, any of the PIC® that work in the PicKit1 do not have hardware serial (UART), so it does not matter. The only exception I can think of is the ADC pins, you may want to save these for sensors, but they will still work for serial.

Pin 5
Common, ground, zero rail...
This must be connected to both devices for any serial to work.

Pin 2
Data is sent to the PC via this pin. PIC® -->> PC

Pin 3
Data is sent to the PIC® via this pin. PIC® <<-- PC

Hi mackrackit,

I'm using a PIC12F683 on my PICKit1.

I've got common pin5 on the DB9 cable (yellow) going to VSS PIC pin8.

I've got pin3 on the DB9 cable (red) going to GPIO.0 PIC pin7.

And pin2 on the DB9 cable (brown) going to GPIO.2 PIC pin5.

All via header J3.

How does that sound?

Dave

[mackrackit]

Sounds like it should work.
Is there any analog on those pins? No problem, just turn it off and give it a go.

Maybe you already know it, MCS has a nice terminal program built in.

[LEDave]

Yes there is analog AN0/1/2

So turn the ANSEL & CMCON0 off.

MCS has a nice terminal program built in.

Is this Microsoft Hyperterminal?

[mackrackit]

Yup, turn them off

Not hyperterminal. MCS - View - Serial communicator.

Mmm

I've got a headache.

So we've got one transmit and one receive line to and from the PIC set up.So do I write a program so that when data from the pc arrives (if it ever does) at GPIO.0 an led toggles.

Would that be a good starting point?

You have a headache... I am stuck in an "art gallery" for the next few hours.

Yes, pick a baud say of 2400 , can not remember the mode number.

SERIN2 PIN, BAUD,[MYVAR]
IF MYVAR = ??? THEN

Something like that....
I will be back atthe shop later.

I am stuck in an "art gallery" for the next few hours.

Strange places 'art galleries' me and my wife visited one years ago and the man from behind the counter came over and said "Would you model for me" to which my wife said (after a pause I might add) " No I couldn't " to which he said " I wasn't talking to you! " And no I didn't either by the way.

Is this anywhere near where I should be heading?

MYVAR  VAR BYTE 

serin2 GPIO.0, 2400,["MYVAR = ", BIN MYVAR, 10]     

IF MYVAR = %00001010 THEN HIGH GPIO.5

Also, the Port (com1) settings are: 9600 bps 8N1. Do I need to change that to 2400?
