Hello,
I am upgrading from a 16F628 to a 12F1572 to take advantage of it's "Precision" 16Bit PWM.
How do I configure PBP 3 to take advantage of it's HWPWM function?
(Needed is a symetrical...
Hi,
That implies one needs to set the Duty Cycle to 80 to get a 4uS On / 4uS Off square wave?
(This does not make sense to me.)
Thanks,

Ioannis,
Thanks for the feedback!
I have been using the attached calculator from Mister E.

I found this:

Which produces this:
PR2 = 0b00001001 ;

CCPR1L = 0b00000100 ;

Greetings!
Having problems generating a clean 50% duty cycle hardware PWM @125KHz using a PIC16F628 with a 20MHz crystal.
The below is from a 2002 Microchip AppNote: (Which specified a 16F628 in...
Hello,
I am interested in using a low cost GPS receiver for producing a TTL pulse for every meter of distance cd travelled. This as an alternative to hacking into the vehicles transmission or ABS...
MPGmike,
Thank you for your feedback.
I will firstly scope out the PIC16F18313.
Peace,

Richard,
Oh no!
Certainly not Landfill.
They were pretty good and deserve a better fate than that!

Hi,
Years ago, I was pretty keen on the 16F88 being a great general purpose PIC.
Wondering what has replaced it for experimentation?
Not terribly concerned about cost but flexibility is...
Ioannis,
I have the beast generating 125KHz from the hardware module quite nicely.
To modulate a data stream, I am simply changing TRISB.3 from an Output to an Input.
Peace,
Jay Zebryk
This might make things easier:-)

Hello,
I am looking for a PBP 3.1 example of how to implement hardware PWM @125KHz using a 16F628.
Attached below is a link to the Microchip App note showing the schematic that I intended to...
Ioannis,
This is getting more complicated than I figured.
Might you be available to implement this for a fee?
I can send you money in advance via PayPal.
Thanks,
Jay Zebryk
Zebryk...
Richard,
I tried your suggestion but it did not work.
As my whole code is >73,000 characters it will not post.
I am using PBPX 3.0.7.4
The PIC is a PIC18F27J13.
Is my syntax / technique...
I have looked high and low but cannot see where this is set.
What exactly is this called and where can I find it?
(I have the U2 Programmer with version 4.51.)
Hello,
I want to store and recall 2 Bytes from Flash on a PIC18F27J13 for pairing up a remote control to a mobile unit.
These are RadioID(RF Address) and RadioCH (Channel#) which are both just 8...
Right. The data sheet says there are (3) ways to clear the "mismatch".
But, just doing the below seems both simple and direct.
INTCON.0 = 0 ' Clear RBIF (PortB Interrupt Flag)
Not sure how,...
Hi All,
I wrote a little routine for putting PIC18F47J13 to Sleep and Waking Up from a key press. Works fine. Interested in the need to read PortB before @ Sleep? Reading various articles, I think...
Charles Leo just confirmed the bad news:-(
(I think I have been down this road before.)
Just did a search on the melabls forum:

RATS!
Hello,
Just setting up the new PIC10F32x Development Board which is both a really extreme chip and a really nice experimenter platform.

Richard,
Wonderful! Works beautifully!
number var byte
number=number+16 will increment high nibble
Again, very clean and easy.
Thank you very much!
Richard,
Wow!
That is so clean and easy.
(I do have a tendency of making things complicated.)
Thank you very much!

It can't be that simple?
What if there were more than 2 Bytes like 10?
No it's not a weatherstation, more like a entry door counter.
