how about the easiest one out there:




Start:

High Porta.1

High porta.0

What does C.0 do? does it flash an LED?

if its used for something else, then it might be a good idea to ad an LED and make it flash on and off as your program runs. I find that it helps me...

It all depends... If i understand your question, then:

A: you want to use EEPROM out of old equipment. As long as its not the reason you car audio stopped working, it should be ok. EEPROM has a...

so, that old code used 3110 bytes and took about 5 seconds to run through.

im still working on it, but i changed to using nmea data, which is something i have never been able to get working...

so to start, my problem is that my program runs really slow. it is a basic circuit using an 18f6680 at 20MHz, a matrix orbital serial lcd and a Parallax GPS module.

Im using an old board...

ive been using a rogue robotics SD card writer for some data logging circuits. http://www.roguerobotics.com/products/electronics/ummc just write data to it with "," in between, and it will open in...

i looked at the PICkit manual, and all i saw was that they had the PGC and PGD lines isolated from the rest of the circuit with resistors. and the MCLR line has a diode on it to stop the high voltage...

i have an EPIC plus programmer that i use for ICSP. after i program, i need to disconnect the lines and then restart my board. is there something i can do so i can leave the programmer plugged in,...

forget the video, i got it working... i had a couple of the ports backwards.. it works good and heres a pic of the lcd with direct camera flash.. it should show up ok in hte sun
...

it seems to appear like a digital watch when "lit" up.. im assuming it should look about the same in light... i don't really know though... if it doesn't work, i will try something else... thats...

here is a picture of the top of the board. its a little fuzzy compared to my other pics, but i was too lazy to go downstairs to get more batteries for my flash.
...

i made the code for this LCD as a seperate file, and just "include"d it into the main program. its actually the first time i have used the include command. now that i think about it, i should make...

the LCD im using is the seven segment type. it had 3 digits and two decimal points. there is 24-pins (one common, 3digits*7segments is 21 pins, and then the two decimal points. im using a 4x20...

Really?? so when we are told that the USA is changing it to the same regulations canada has when you guys try to come up here, its not really true???


so i got the board working, and it all...

my stuff just got here a couple minutes ago, and so i soldered a new PIC to the board, and it WORKED!!!!

thanks to all the guys that had suggestions about why it didnt work, but it seems good...

sounds like a good trip... i think to fly we need a passport now, but to drive you just need two pieces of government id..

so i noticed a while ago that i had shorted one OSC pin to 5v, would...

i would come give you a hand, but "unfortunately" i dont have a passport!!! and i have to wait for Puralator to deliver more parts!!!

just wondering if doing it this way decreases code size too, or if it just makes for less typing??? im working on writing some code for this project (if i can ever get the board to work) and i know...

Put an LED on your output and to ground, if it lights up, then its High!!

check your power supply too... i think they say12v 1A

i de-soldered the pic from the board, everything looks good under there... no solder bridges or shorts of any kind.. everything looks good... i ordered another PIC so it should be here on monday...

ok, i was just kind of curious... i get them from Digi-key and they come in a vacuum sealed static bag with one of those little dessicant bags in it and a humidity tester... the 16f ones, come in...

GOOD TO KNOW... i learn so much from all of you on here.... i know these PICs say they are static sensitive, but how bad is it?? should i be wearing a strap every time i think about looking at...

im not sure... i have tried it on both enabled and disabled. those were taken from the config settings of my programmer.

im still working on this board, i have checked the design twice more, and still dont see anything wrong with it.. when i connect the battery, i get just under 5V (and the PIC is good down too 2v). ...
