Hi Charles (long time - no hear),

Did you ever find the answer to this problem? I'm looking at using the chip, but not if there's unforseen gotchas.

Thanks!

Thanks.

Hi Art

Wish we could delete dumb posts. Was a typo. Bad character slipped in there way to the right of the screen.
Sorry.

Hello,
Just starting a program after quite awhile, and am encountering "Error Line 103: Bad bank number"

Line 103 is just a variable declaration...
X VAR BYTE

The PIC is a PIC18F4685....

Someone posted source code for a small C program on the internet, but I'm not familiar with C or what's necessary to compile it. If anyone is using a C compiler for Microchip and wants a small...

Hello Charles,
I know that you have extensive experience with XPORT, so would like to ask you a question. Is 115200 the maximum baud rate when using this device? What is the fastest baud rate...

Just came across the WIZ108SR RS422 to Ethernet adapter module, and was wondering if anyone has used this module in a PIC application?<BR>Would appreciate hearing about it.&nbsp;&nbsp; Thanks.

Thank you, Darrel.
Happy New Year.

In compiling a program under 2.60L (3.0.0.5), for a PIC18F6722, I am getting a message saying:

Message[301] (path) GC32.asm 2127 MESSAGE:Temp variables exceeding T7.

I am curious as to it's...

Assume your PIC has been programmed, and it's I/O pins are doing their thing. Is there any rule about what happens to these I/O's when you reprogram the PIC? To my surprise mine seem to hold their...

Forgot to mention... I assume you have 2 suitable size caps from the crystal leads to ground. Somewhere near 18-22 pF depending on the crystal.

Well, I don't know about the PLL, but I expect we should get your crystal oscillating first. I am using a 20MHz crystal with a PIC18F6722 and it oscillates fine using:

@ __CONFIG _CONFIG1H,...

Well, it sure does the same thing, just on a different scale! Good find!! The Youtube guy isn't taking temperature into consideration of course, but he does have speed control and everything else. ...

No kidding. Good thing we weren't holding our breaths! It isn't that it can't be done some other contrived way, it just seems like the effort should be put forth to implement some of BASIC's...

I know about not using serial port/s during an interrupt, but how time consuming is something like this?

ARRAYWRITE TEMP,[DEC2 HOST,".",DEC2 ADDRESS,".","125",".",DEC2 V,".","*",13,10]

(I guess...

Very good reminder in #7.

I think I'll just need to go through the (INT0) handler and just pare the heck out of it.

Oh, thanks very much for that Charles and Darrel. The board is part of a security system board, and didn't start out complex, but seems to be getting that way. I have two uart interrupts and...

Bulldoze the code, and rewrite it.

I have a program using 4 different DT_INTs, and to be honest, it's getting a little hairy.

I've sort of lost track if an interrupt is enabled or disabled. Is there a quick (lazy) way for me to...

That works perfectly! Thank you.

I've been around long enough to know a dumb question when I see it, and I'm pretty sure this is one.... but here goes.

I've got a some hardware connected to a PIC board that can generate an...

thank you mister_e.

I see how I can isolate the lower 4 bits of a port and READ from them

anyvar = PORTF & $0f

but don't know how that pertains to a WRITE. Is that what you mean?

In an application, I have wired the lower 4 bits of PORTF to control the inputs of a multiplexer. Right now I have assigned the variable like this:

MUX VAR PORTF

but really, it's only the...

Please disregard. TRIS overlooked.
