Hello

I have been playing around with the MIBAM code for quite a while. Sadly, I don't get it. The results that is. Sometimes I will have working code only to come back the next day to find...

Hello

I'm trying to write a set of universal subroutines that I can transfer different predefined output pins into as opposed to writing a number of subs that except for pin...

Hello,

I added these lines and the display is alive and well.

Thanks




Define HSER_TXSTA 20h ' OUTPUT B2 PIN 8 16f628a

Hi all

Is there some problem in using the SPWM code and "debug" together? I use debug with
a VFD display for trouble shooting but have not been able to get it to work when the SPWM...

Hello All

A while ago I tried using Darrel Taylor's "Instant Interrupts. The demo showed that

three separate items could run (seemingly) at the same time using this interrupt scheme. It is a...

Thanks for the reply. Building them is a possibility. The real question is "where have all the Triklits gone". I can find no new information on them. Are they still being made or has the quality...

Hello

I started looking at ways to make a Christmas light LED string with each lamp site being a PIC serial addressable receiver. Then I came across TRIKLITS which is exactly what I had in...

I have noticed that the keypad display output occurs on the release of the keypress. The setup I have which is like a "musical chairs" type of game requires variable index capture of the first player...

Corrected to:

DEFINE KEYPAD_COL 4 ' 4 COL keypad (0-3)

DEFINE KEYPAD_COL_BIT 0 ' COL 0 = PORTB.0 (wires start at PORTB bit 0)

Keypad is now working properly.

Many...

The problem is that PORTB.0 not detecting

I swapped B.o and B.1 keypad lines - problem remains with B.0

Changed to another 16f877 chip - problem remains with B.0

I noticed your last post...

I will check further. I am using the f877 pic. Note that I tried changing this line to "4". Is that wrong?

DEFINE KEYPAD_COL 3 ' 4 COL keypad

Looking at it now I realize that its probably...

Thanks for the quick response.
I have tried the code and it works. However there is an issue. I have a 4x4 setup but it acts like a 4x3 keypad. I can get digits 1 through 12. If I change the define...

DOH! I had a detailed question but it got cleared. So here's the short-short version.

Has enybody included a 4x4 keypad routine in with DT's instant interrupts? It would most likely use port B...

Using the OSC2 1 MHZ method I was able to get a reading of 1.0016 MHZ with an OSCAL value of $39. A fair tweak from $2D.

I wrote a little pin out program and read it with a frequency counter. With a good calibration value for a 4MHZ clock, the pin frequency was 97.48 KHZ.

With a 12F629 PIC that lost it's calibration...

Another "forest for the trees" thing again!

REG GPIO - BIT 5 Got it! Thanks.

The value in the last memory location shows up in the calibration section of the memory read. The value was still...

I have a dedicated 16f84 pic tied to a LCD display which allows me to use Debug commands to readout parameters with a single wire at 2400 baud from PIC's under development.
I am now working with a...

I'm working with a fairly straight forward program code for a 16f84 chip. As I approach the 760 words used point I noticed that instead of reporting " Success 760 words used" the compiler is...

Yes, exactly. That is what I'm trying to do. Make my USB input look like it's a USB keyboard or keypad. Is there some built in code or "tag" within these devices that makes the PC recognize them as...

Thanks,
I have investigated your suggestion with mixed results. In the Powerpoint setup screen I am able to select items in the text boxes by having the pic send ascii codes for keys 1...

I didn' see anything on those sites that looked useful. I think I need a patch that will take characters input to com4 and make them look like they came from the keyboard. A USB keypad I have does...

Hello,

Part of my PIC project involves the control of Powerpoint presentation slides which can be addressed by keyboard entry (1 enter, 2 enter etc.). I have set up a serial to USB...

Using pin 25 RC6/TX and monitoring with MCS serial communicator at 9600 baud I get a repeating string of garbage characters. Hserout ["hello"] test result was the same. Isn't there an issue with...

I use DEBUG to get to my serial pic LCD readout at 2400 baud. I have been trying to replace the hserout functions in the "string storage" thread with my usual debug output with no luck. I get...

"Not previously defined" error was caused by having PortA instead of PORTA. It's 4AM and I think MPASM is the cause of some strange chip behavior. Only when I uncheck MPASM do I get back to a...
