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.

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 "http://www.voti.nl/blink/index_1.html#16F630" 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!

Rapid Pulse LED Program

Hi there! I have successfully been making some LED hula-hoops but my ultimate challenge lies before me: I want to program colour-changing LEDs so that they pulse ultra-fast and appear 'white' when at standstill but leave rainbow trails when they move. I believe it to be an optical illusion caused by the pulsing... I assume this requires a PIC program but I have no idea where to start or even if I am on the right track - does anyone out there know how I might achieve this? thanking you in advance, Amelia

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

Problems programming PIC 16F648A with progPIC 2009

I recently bought a PIC programmer kit from www.velleman.be and tried to program a hex file to a PIC 16F648A and it keeps failing. I have a suitable power supply, an RS 232 cable connected directly to a computer (no usb to rs232 convertor) and it is in program mode, and it is inserted the right way round. I tried programming the included PIC with the included demo hex file and it works fine. However, when I import my hex file, it shows the last set of characters as random ones (not letters or numbers) so it looks like there is something wrong with my hex file. Do I have to compile it differently to work with PICs, and how would I convert this?

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

MPLAB and PIC16F628A, basic EEPROM functions wont work

Getting started with PICAXE? Answered

I want to get started using PICAXE microcontrollers after using both PICs and AVRs before, and I have already learned the BASIC language, it's pretty easy, as the name would suggest. My main interests with them are that they can be easily programmed with two resistors and a 3-pin serial cable, they are easy to program and have ADC inputs, and also audio functionality. What would be a good place to get started, I was looking at the 08M, but it looks like it was recently discontinued and replaced by the M2. The reason I don't really want to move on is because I have just learned the pinouts and functions for the 08M, and also a lot of projects here on instructables utilize it. I was looking at building the tic tac tunes.I also noticed that it has the markings "12F683", so does this mean I could just buy a pic 12F683 chip and use it as a picaxe? Are they identical or is there a subtle difference in them. I also noticed that the audio functionality seems to be very limited in that the smaller chips only do polyphonic notes, and the mid sized chips only do mp3 from eeprom, and only the very large 40 pin chips do audio. What is the smallest chip that supports a full range sound file. Memory shouldn't be too much of a problem as the clip is only about a second long, so one with 256k should be fine, as long as it features internal audio. My last question is what should I buy, as in chips (universal and common experimentation chips), and any other accessories I may need. By the looks of things, all I need is the chip, a headphone socket, resistors, and a download cable.

Do I need PIC microcontroller? Answered

My question is simple - imagine device with a single button (touch, whatever), it is either on (sending signal) or off (nothing is happening). This device is connected through usb to a computer. Do I need, in this device, a PIC (or any) microcontroller? Wouldn't just be sufficient to create a driver in my computer that would just recognized the device and received information if it is on or off (sending e.g. el. signal, letting the current through or not...)? I am a complete beginner in this, and this answer would help me understand more how it works. I have a little background in electronics. Thank you. P.S. if you still have a problem to understand what i am talking about, imagine a simple circuit - battery, switch, LED (+resistor), you switch on, LED lights, you switch off, LED doesn't light - now change LED for USB and let some custom program in a computer open a window with "hello world" whenever you switch on now.

Micro controller help

Hi everyone, I'm looking to get into the world of micro controllers but I have no clue how to decide on which one to start with. I have experience programming in VB on almost a daily basis and a class or two a few years ago in Java and C++. I don't anticipate programming being a hurdle. My main goal is to work with using my Android phone to automate certain parts of my life, such as automatically turning off the lights in the house and killing power to devices in "stand by" mode. I see a few books about the ease of combining arduino with android, but the reviews all state that the books assume proficiency in one or the other, meaning it's either targeted to an android programmer who wants to dabble with the arduino or someone who has micro controller knowledge who wants to incorporate the android. I have neither and need something basic for both. Something that starts from the very beginning. How the two connect. How they talk. Are their standard libraries and objects that they use? things like that. This is less a question/answer and more something I'd like to have some discussion on. Feel free to ask any questions if I missed anything. Thanks in advance.

I am lost trying to find out how to wire this thing. Can someone tell me how to connect the L298 Module with the Pic kit and the basics of how to program it (not code just the concept). I already connected the stepper motor to the coil pins of the module. Thanks

What do i need to buy in order to program an 8-pin PIC microcontroller?

I am trying to build/sell mod kits for 360 controllers (to make them rapidfire of course) and i need to know what i need to buy. I have 2 serial ports on my computer, so it doesn't need to be usb. I just want to find the cheapest way to take codes off of and write codes to microchips. I saw this but i was told that i would need to get other items to add to that to be able to program a chip. Also, is this chip similar enough to the ones that they use in the kits/ mods they sell on ebay? Would this chip work? Any answers would help very much.

Does anybody know of a schematic to program an 8 pin picmicro controller such as: 12F675 12F508 Just those specifically because they're 8 pin and I have them. Correct me if I'm wrong, but one of those 2 has 8 I/O ports, which leads to a lot of possiblities for a small area. Also this will be my first real pic project.
