http:www.pulsar-electronics.co.uk Hi all,

I am trying to replace an existing meter with a LCD chich puts up a block at a pint determined by the input on two of the ADC channels on a PIC.

I need to calculate the Angle and the phasor AMPLITUDE.

I have x on one input and Y on the other. I know I need to use ArctTan function, but I also need to store the results in two floating variables.

I'm using Crownhills EXCELLENT PICBASIC compiler, and any examples of code would be GREATLY appreciated.

Regards,

Sean Goddard

This program senses a high then a low state on RA3, adds one to a counter and then moves counter to Portb then loops back counting each high/low. Problem is the program only counts once and then ignores high states on RA3. To alter states I use 10K resistor and 5V for high and ground for low. All porta pins are tied to 5V via 10k resistors. If I ignore the counter and increment portb directly the program works. I tried a different port, RA0, with the same result. The pic is a 16f84. What gives. My test circuit is similar to the one shown in the book.

Im looking for a 32/32 bit divide function that will work with the PIC18F452. I used a function written (well actualy it was the modified AN575 microchip stuff )by a guy called ingvar gillholm which worked a treat on a 16F877 but unfortunatly wont work with the 18F series. I use picbasic pro V2.41 with the MAPSM assembler. If anyone can help i would be most greatfull.

I have a problem. I just got the PIC16PRO programmer and using MPLAB. I'm new at PICs but have been programming for the 68HC11 for quite some time, so the code is easy to pick up. To test out the programmer I downloaded an LED program. Simple program that just turns on and off an LED. I programmed the chip and verified that the code was there, but when I hook everything up, nothing happens. I know the code is correct and so is the schematic. Is there something I'm missing? The PIC I'm using is the 16F628.

I think the answer to my question is obvious, but in case there are minds much more clever than mine out there: Is there any way to write parallel re-entrant routines for the PIC16F84, that is, routines (which use more than just W for parameter passing) which can be called from both the mainline and interrupt code without having to disable interrupts in the mainline?

I am programming a 16f874 and need to use six anolog inputs. I am using the a/d converter and am having trouble getting accurate readings. One a/d conversion works, but when two are programmed in, it still only takes one a/d conversion and gives that as the input for both a/d conversions. I am using a 4Mhz oscillator and have tried nearly every route. Does anybody have any sample code for MPlab that take more than one a/d conversion that I may compare for troubleshooting.Thanks.
