I know that it is some years ago now that you have postet this great simple way of making a capacitive touch-sensor.
But still I would like to thank you for it, it just helped me on making a...

I am not really sure that I understand your question.

I assume that you have an change on PORTA interrupt and that you want to know which of PORTA pins that triggered your interrupt.

Maybe you...

I have used pull-ups up to 100 K without problems.

I know that you don't like weak pull-ups I remember from one of my other thread's, but I would really like do know what the problem about them...

The touchpad that is connected to the board have 1.5 metre of cable.

I have only used the capacitors and the serie resistors for products that needed
to have an approval.

But if I understand...

Hi Mister_e,

I normally do the debounce in software.
I have always used capacitors on inputs to suppres noise, but maybe they are not necessary?

Hmm, really on the 16F630 I use it work on PORTA. :)

I am not having problems programming the weak pull ups.
I just want to know if I should use a serie resistor and a decoupling capacitor
as I...

Hi, I am designing a board that is connected to a momentary switch,
normally i just use a pull-up resister and a series resistor and a capacitor,
the series resistor and capacitor work as a...

Yes! I have some experience on capacitive water level sensors, they can do what you need.

Hi mister_e,

Dooh, yes of course it's: @DEVICE 12F629 :o

Thanks!

I think that I will stick to my pull up resistors, because I will not take any chances.

I have about 300 pcs. of my application with pull-up resistors in the field and they work just great, but...

Hi,

I have and application using a 12F629 using 4x10Kohm pull-up resistors,
but should there be any reason not to use the internal weak pull-resistors instead?

That would save me some space on...

Hi,

I would like to use GPIO.3 as an input on the 12F629.
But how do I do that in the right way?
Is this the right way?


@ DEVICE pic16F628, INTRC_OSC_NOCLKOUT, NO_MCLR

Hi,

I am working on a little controlpanel with a 12F629 pic.

I want to protect the input ports from ESD and I think that the best way to do that is to use a transient diode.

But how do you...

Hi,

Thanks to Tissy and Chuck for your examples.

I can conclude that you don't use the BUTTON command when you "read" a switch.
I just thought that it was possible to set up all the parameters...

Hi,

I'm trying to switch a relay on and off with the help of BUTTON and TOGGLE command.

It's working but not the way I want it to work, because when I press the button
the relay is switching...

Waaauu, that's what I call a quick reply.

Okay, I will use a 275V VDR then, because it's for use in all 230V AC countries.

Is there any rule of thumb that I can use, to learn how you get to the...

I have made a small control panel using a 12F629.
I'm controlling a relay that has to switch a pump or a solenoid valve.

Since these inductive loads can couse peaks when switched I would like to...

Hi Tear,

Sorry to say it, but I think your on a slippery slope.

I agree that it is really fun to play and work with PIC's but I really think that there most be an easier way for you than to use...

Use PAUSEUS 500

Now I solved the problems.

The first thing was my JDM programming device, when I use:

It is not possible to program the PIC again with my JDM or Velleman programmer.

I solved the problem by...

Hi Bruce,

Right now I use the K8048 from Velleman. I like the programmer but I really don't like the software called ProgPic2.

The code that works is a HEX file that I have downloaded from the...

Hi,

What is wrong with this code, I know that is has to be very simple but I can not get it to work! :(


I have tried to download a hexfile for the 12F629 that blinks GPIO.0 and 1 that is...

Hi Dave,

I'm not the one that is trying to messure on pin 13 :)

Well I agree on that you could stop the oscillator with your scope prope,
that's why I asked Netjammer if he was messuring...

Hi Netjammer,

I think that I misunderstood your question. I thought that the problem was that your program would not execute.
Are you trying to messure directly on the crystal?
