Dimmer

[mister_e]

Can anyone tell me what I am doing wrong?

You're using PM instead of MPASM to compile your code

if you want to use PM, you must use the @ DEVICE directive instead.

See the Faq about that. There's a whole thread about how to set config fuses in your code.

You're the MAN! Totally missed that one. Thanks!

Hello - I am trying to build the Dimmer Circuit as described and was wondering if someone could critique the attached circuit diagram. I have built this and do not seem to be able to get it to work and if it is not my design then it must be my code (both of which I obtained here). Any comments will be appreciated. I am using part numbers, schematic and code that are described here: http://www.melabs.com/resources/samples.htm#submitted
Thanks! Atom058

Here's the schematic....

%%^%^&*&!#@$! it's my silly mistake. I will have to update the whole thing soon. Use...

You only have to move 1 wire...

PCB mod... really easy

Mister-E - No harm done! Thanks for the quick response! I will give it a try tonight and we'll see what happens.

I was trying to program a PIC12F675 to work with this dimmer design and I am obviously missing something. I copied the code from the Dimmer example and it was not working so I moved to a breadboard to do some testing. I can not even make an output on these PIC's go high! I know I am missing something but I can't imagine what it is! Here is the code - as simple as it is:

@ DEVICE INTRC_OSC_NOCLKOUT & WDT_ON & MCLR_OFF & PWRT_ON & BOD_ON

PAUSE 500
CMCON=7 ' Disable analog comparator
ANSEL=0 ' Disable analog converter

TRISIO = %11111111
TRISIO.0 = 0
TRISIO.1 = 0
TRISIO.2 = 0
TRISIO.3 = 0
TRISIO.4 = 0

HIGH GPIO.0
HIGH GPIO.1
HIGH GPIO.2
HIGH GPIO.3
HIGH GPIO.4

Start:
GOTO Start

END

Now, correct me if I am wrong, but I should be able to measure 5V at each of the 5 outputs above. I get nothing. I have tried several PICs and get the same results. I've written hundreds of programs for different PICs and this one has beaten me. I know the solution is unbelieveabley simple, but GEEZ!
