SOLVED.
For those interested, with the help of Charles Leo this is solved. As it turns out, this is one of the cases in which if you have DAT and CLK pins configured as outputs, and MCLRE turned...
Not the answer you're looking for, but have you looked at the capacitive sensors available from Azoteq? You can buy them through Mouser. A single channel costs something like 43 cents. They can do...
There isn't a meLabs programmer section so I thought I'd start here. I'm using the U2 programmer (latest code) with MicroCode Studio. MPASX (latest), PBP3.0.7.4.
Currently I'm doing a few projects...
Before you close the thread...
Did you try turning off Capture/Compare/PWM?
CCP1CON = 0?
To the point of not pulling down to 0 volts on the pins, turn off global pull-ups:
OPTION_REG.7 =...
I'm posting a follow-up to this in case it may help someone else. Though I'm really not happy with this device (the clock jitter in INTOSC mode is too severe for my tastes) here's what I've found...
After banging on this thing for a few hours I'm beginning to think this device is really chewing gum with metal legs. ;) This is kindof' an odd device; its like a "PIC12Fxxx" but with a "PIC16Fxxx"...
I'm working on a couple of projects that use interrupts, specifically interrupt on change Port B. Many projects can be broken down into what I call "push a button/do something". Often times, the...
This application only required a range around 25 feet. We did an ad hoc test of the system and got more than a 300 foot range using a ~0.75" ceramic antenna internal to the "remote" unit and a stub...
Just keep in mind you must run everything as "Administrator".

I just finished a project using Linx Technologies 900 MHz transceivers. Mouser has them:...
Thanks very much. I had looked on melabs website and though I'd find it there. Anyway, thanks again.
Is there a version history posted somewhere for whats changed in PBP3? For example, from 3.0.1 to 3.0.6.
Thanks.
@SVRZIC: This is becoming a language problem of epic proportions. I've negotiated a full weeks "company" with a lovely Asian girl in China in less time and with less confusion than what's going on...
This is really an edit, time expired when I went back...

@funnydrummer: You don't need resistors on the base of an emitter follower so you can delete those entirely. If you're opposed to using resistors for current limiting (which is the only reason I can...
LOOK MATE. If anyone here is whining its the people that know nothing about electronics, tackle these kinds of projects and then get on here or any other board asking for help on the simplest of...
I don't know if it's the language barrier or what, but hell, I'll give it a shot, again.
First, I don't know what the files are you keep posting, they have SCH and BRD extensions. I'm guessing...
Your schematic looks a little odd for the displays. As shown it looks like the leds being used are offset in different directions so if the they are physically pushed together there would be rows and...
Ok, after way too many emails from way too many people I've posted the files again. Here they are: http://www.scarydesign.com/144led/144LEDGERBERS.rar. Get them, save them, repost them somewhere...
Well, I'm intrigued. This has also raised some questions as to my ability to read a data sheet...
Going back to Table 17-1 in the datasheet. MC refers to "TAD vs. DEVICE OPERATING FREQUENCY". In...
I'll take a couple of shots in the dark... don't be offended...
You know for certain that the TRIS is all set correctly? You only show the ADCON registers...
You have ADCS2:ADCS0 set for...
Look at the attached schematic. Whenever you design a circuit around an opamp you should use a compensation cap in the feedback loop as well as good power supply decoupling. In most documents this...
I'm guessing you mean "MCP4902"? A couple of basic questions... you have compensation in your feedback loop? If you don't have a cap there you're asking for problems, especially with a 741. If you...
