Bob,

I've used the ubiquitous MAX232 to a PC RS232 port with success in an automated tester using Hserin and Hserout. I'm jumping on on this cause I use the PIC16F876A also.
The DB9 on this end...

That's ok. Better late then never. Hopefully it will be an appropriate response to someone with a similar question. And thanks for the tips!
:cool:

Connect the HPWM output of a PIC to a low pass filter to develop a variable DC voltage. Use that DC value on the base of a power NPN transisitor configured as an emitter follower current amplifier....

Here is a link for the BMP format..

Anyone have any ideas for code to extract the pixel data? I would suspect it to be...

1st, I crammed everything to gether for this post. My code looks much nicer than that.
But it does bring up a question I had: Where does the PIC start excecuting? If I don't tell it where to start?...

I think what some of the older guys are talking about (And you know who you are) is "etching" your own PCB versus sending off the Gerber plots to a fab house and having a PCB done. Not many of us do...

Sigh... I had PortC.0 shorted to PortC.3 on the LAB-X1 U7 pin 2-3 after putting in R11. So all I had to do was change SWDN to another port... Namely PORTD.3.

Anyway, the code above is working...

Hi guys,

I'm having a problem with Portc.3 (Pin 18 PIC16F877A). I have it tied to a 4.7k ohm resistor to +5V.
When I pull it (pin 18) to ground and hold it there for more than a few seconds,...

Any decently engineered electric vehicle already will have regenerative braking. That is a fairly old and well understood concept. Any electric motor can be used as a generator. When an electic...

That is nice. I haven't the 1st clue about VB.
Thanks aratti!:cool:

Technical advancements will have their benefits and drawbacks for people. The question is: What are the trade-offs? I think for the next generation or two, the benefits will out weigh the drawbacks....

I am using a work computer and cannot in good concience load an untested excecutable on this system. Can someone at MeLABS run it and check it for me and let me know if it does as advertised and...

I would like to see an online Syntax checker that could also check my code size and suggest a suitable PIC for the job. I'm thinking of something similar to Advanced Circuits' DFM service that will...

How about an online Syntax checker? Or something that could at least count the amount of code you used and suggest a suitable PIC for the job? Or perhaps let you know if what you've done will even...

As Bruce pointed out the correct syntax is "gosub R_FWD". This is correct in my code.
But neither reply answers my actuall question. Also, as a fall back position I intend to hard wire the PWM...

Hello again.

Still using PIC16F876A...

This bit of code works quiet well: ie The PWM appears as expected on both channels.

DEFINE OSC 20 ' use 20mhz xtal.
DEFINE HPWM1_TMR 2 ...

Now that I'm pretty sure I have the software settled... Has anyone been able to simulate a PIC16F876A with MPLAB's Simulator? What's the trick? I think I have everything set up right, it doesn't...

Now that's what I'm screamin... Thanks Mister E. This is all running in an IF/THEN loop.
So to recap... My syntax should look like this:

PORTB.6 = PORTA.2 & PORTB.2 ?

And judging from what I...

I guess I wasn't very clear about what I want to know. I'm holding back some info because this circuit may be very valuable.
Presently, I have the 2 HPWM outputs going to a quad 2-input AND gate...

Hi folks.
Some init stuff: I'm using a PIC16F876A.

DEFINE OSC 20 ' use 20mhz xtal.
DEFINE HPWM1_TMR 1 'Use timer 1 for both channels
DEFINE HPWM2_TMR 1

Micrel makes a very good set of mosfet gate driver chips. Find their data sheets here. http://www.micrel.com/_PDF/mic4423.pdf
They are dual output, so you would need 2 of them for 4 outputs. Again...
