PIC Microcontrollers

Hello. I'm just making my entrance into the world of microcontrollers. But as I self learning everything I have a few questions. I recently purchased 2 PICS (16F648A) and a programming board. The board works fine and I got it to connect to the computer and reconize the PIC. I guess my first question is, Is all hex code PIC specific? Meaning would I be able to use this code "" for my PIC? The models are very similar but not exact. If not, I would like to do the standard "Blink an LED" as my first project. How would I write my code for this PIC and what materials would I need? Thanks!

Pic Basics

Is there a website to learn about how to use picmicro's really easily? I realize that there are some instructables about it, but to be honest they arn't very helpful. For example, I have no clue what the crystal does, why you need it, how to hook it up, and how much voltage they need because I need to buy some.

Custom PIC

Savage innovations does not offer a small OOPic chip. OOPic is my favorite MCU and I want a small one. Soooo, I decided I want to make one. In theory, The process is simple. The OOPic 2 is a PIC16F77 with custom firmware. I ordered a similar chip (PIC16F876A) to put the firmware on so I basically have a smaller OOPic. Savage innovations does not offer the OOPic firmware as a download so I have to extract it from my OOPic2. Here's my questions. Will a JDM2 programmer be able to extract the firmware? Will WinPic800 work to do this? Will this erase my OOPic's firmware entirely? Is it even possible? I would like some input and if you guys say it will be okay, I am going to do it. (I'll post and ible if it works.

PIC Programming Software

I am just starting to get into PICs, problem is, I can't find a program. All these tutorials on PICs on Instructalbes talk about the hardware, but not very many talk about software. I am pretty fluent in VBasic/Basic so I would like a developer that works in that language or C/C++. I have PIC Prog, but that just downloads it. Anyway here's what I need help finding: -Free devolpment and compiler program -Preferably programs with Basic or C -Works with JDM2 programmers. Yes I have MCU experience, but it's been with an OOPic. I can't use it on everything so I am switching to PICs. Anyway if anyone can help me with software solutions, I'd really appreciate it.

Getting Started with PIC

Hello again, I'm looking for suggestion or first hand accounts on getting started with programmable IC's. I'd say I have enough basic electronics skill to get by, but I'm completely new to programmable chips. So I'm asking where is the best place to start? I'm mostly just looking for hobby stuff at this point. The PICAXE stuff seems simple enough for a starting point, anyone have first hand experience there? I should note I don't have any access to programming though parallel ports, and I'm running Windows Vista, so any set up would need to support usb and my os. Additionally any recommendations on some reading would be nice too. Thanks again Nic

can ATmega and pic microcontrollers communicate with the rx and tx pins?

Hi. i am starting a project that will involve about 4 small boxes that have simple switches and led's connected to them. they will then all be linked to an arduino but maybe later on i will replace the arduino with a pcb that has an ATmega chip on. same as my arduino, which has my custom program on. i would like as least wires as possible. so by using the receive(rx) and transmit(tx) pins i would only need 4 wires. power, ground, rx and tx. BUT. pic microcontroller chips are alot easier to program and are cheaper too. i would not be able to use a pic microcontroller to control them all at the central hub so i would need the arduino and pic chips to be able to communicate without problems. only sending basic commands like: 0001 0011 or LED 1 HIGH. i just thought i'd check it could be done before i buy my parts. if it can't be done is there any way to make it work or any cheap alternatives? thanks, Luke

PIC Programmer Com Port?

Hello, yesterday, I bought a PIC16F877A Microcontroller and This programmer. I also installed PicPro USB. I am using the serial to usb cable that came with it. The programmer has a location of  Port_#0001.Hub_#0009 in device manager. Now when I open PicPro USB and set it to  port 1, It gives me an error saying: There appears to be a problem accessing the COM port. I cant seem to find whats wrong. [Edit] I think that It is connected to port 24 (hence its name: Prolific USB-to-Serial Comm Port (COM24) ) and the problem with PicPro USB is that it can only have 1 digit port numbers, how do I fix that? Thanks.

How can I attach El wire to a PIC using an accelerometer as a switch?

I would like to use a PIC that would turn on the EL wire only when it is dark out via a small photocell. I would also like to incorporate an accelerometer that would detect when the person is walking or running (it is to go on shoes) as well as fade in and out. To turn it off to conserve battery power, I would like to incorporate a small switch so that when the person is home he can turn it off. Most of all, I would like to use 3 volts with a lithium ion cell or two AG13 batteries. I have wanted to use a CMOS 555 but it would make the circuit very complex very quickly which would make the circuit heavy and very uncomfortable to wear.

How accurate do VGA timing signals have to be?

I'm looking to try to drive a VGA monitor using a PIC 16F690, on a 12MHz clock (3,000,000 operations per second) The most accurate the signal from the PIC can be is 1/3 uS, but the timings given are to 1/100 uS for the 640 X 480 @ 60Hz standard. Overall, each frame does come out to a whole number of cycles, so does the exact duration of each line matter? I've seen a PIC output very basic graphics on a 4MHz clock, so I would expect it to be fairly simple to just light up the display on 12MHz. Alternatively, is the display smart enough to fit whatever is fed into it onto the screen? Thanks for the help.

MPLAB and PIC16F628A, basic EEPROM functions wont work

Hello all Ive got a query about the simulator in MPLAB.  I'm using a PIC16F628A-IP and Ive written a couple of subs to run the EEPROM functions, but when I try and run the program in the simulator and observe the registers, I'm noticing that EECON1 is not accepting bit changes, and when reading from the EEPROM, i get as far as getting the correct value into W register (MOVFW EEDATA), then the next step, simply a RETURN command, for no reason wipes the W register back to 0 and hence the routine always returns a 0 Can somebody have a look and see whats going wrong, this is one of the easiest routines to write as there are so many examples on the web, Ive even used code straight from Microchip's Code Library and that didnt work either, its driving me MAD!!!
