I am programming in circuit. There is no other load on any pins.
I am trying to program the 12F series with a MElabs U2 programmer. These are new parts, 12F635s and 12F683s.
First of all, the programmer tells me that the devices have the wrong IDs. Next, when...
For wheel speed, a strain guage with a weight, set slightly off center, will be a pretty linear indication of wheel speed. A modulated LED at a certain point in the wheel well, and a photodetector on...
If you have a multimeter with a diode test function,put the leads across the various transistor leads. When you get a diode reading, the positive supply connection will be the negative lead. In...
Look on Microchip's website for a high voltage generator using a PIC. It is informative and pretty cool.
Basically, you are creating an instantaneous high voltage at a minute current. Anything you...
The simple answer is no. It looks like you cane rewrite this using "select case", and choose the goto destination accordingly.

I hope it's this easy for you Hylan. Somehow the on screen compile buttons got mixed up on the new version. While I thought I was hitting the compile button, I was hitting the ICD compile button!...
Here's an interesting one... My old laptop's screen died. I bought a new mini laptop to replace it for travel. I put my registered PBP2.50a onto the new unit along with my Melabs programmer software...
I started on PBP, and have designed hundreds of programs for commercial products. I was tempted to play with Swordfish for 32 bit variables, but since Melabs released 2.50, I have had no need. The...
Is it possible to inject an external clock signal and use the PLL feature of the 18F processors? It looks like it is only available with HS and intosc modes.
Thanks,
Ron

What do you mean by self contained?
How much program/RAM space do you need?
Put a 1K resistor in series from the LiPo battery to A.0 PERIOD.It's just safe engineering practice. I don't see a need to post the code, or parse the replies any further.
I have a button read...
Once you can cook small pieces of toast on a PIC, you will have catastrophic failure in short order. This I know from plugging the programming header in wrong. It worked for a while, drawing more...
What is the average, not maximum data rate for the GPRS modem?
How about this, I believe that the $C0 is the beginning of the second line.
PAUSE 500
lcdout $FE,1,"THIS IS A TEST LINE1" 'LINE 1
pause 500
lcdout $FE,$C0,"This should be line2"
A file is a file. Whether a .jpg, or text, you need to know where it is, how long it is, and the destination. You need horsepower, and 32 bit math. I sent pictures from an SD card, to an SD card...
Hey guys,
I've been building a PC interface for a PIC app, and I need to do some bit work. I've got .net2008. In some web help lit, there was an example using bitAND, bitOR, and bitXOR, but...
Here is a set of subroutines for encoding and decoding RF transmissions using PIC18s and PBP2.50a. Originally I posted in off topic, but it was suggested to move it here. I hope someone can use it....
This one does not require a separate power supply...
OK, here it is. These subs will take an eight byte block of code, and encrypt it, then decrypt it. The key must be exactly the same for encrypt and decrypt, and don't mess with "Delta". This is only...
Use Serin to put a byte into 'var' ; If you don't use an RS232 level converter, you will need to do it with the Serin statement. Check the manual.
PortB = var
high PortA.0
My belief is that when bit #31 is set, it becomes a negative number in the eyes of PBPL.So it would be -2147483647
Hey guys,
I'm stumped with the Swordfish XTEA encryption code. Changing it over to PBPL 2.50 is difficult due to the fact it will only support 32 bit signed integers, not unsigned. Plus, in the...
