This tutorial is a modular way of adding interfaces one at a time. Though it was designed for PIC16F family of chips it can be easily be ported to hardware and software in assembly are included. Allen
Hi, You will find all you need in this first link, the others might also
Hi, For beginners Assembly look at these
Hi, This site gives Assembly and hardware details of 7 seg displays and IR sensors etc though you will have to build them together or keep searching if you want a ready made solution, though you won't learn much that
Hi, As Niradj rightly says you are asking for a mountain of information. Have a look at these Free Assembly tutorials and work your way though one of them to give yourself a good foundation in Pics and
Hi, Its easy enough to do what you want, you can find a great deal of help in the tutorials listed below. Be aware that many Pic output pins default to Analogue mode so you must set them to Digital for Led use. If you want a led start up code in Pic assembly for the 628A just say. htt
Hi, See a tutorial like this one
Hi, Have a look at these tutorials to see how its done - loads of others out
Check out for Nigel Pic Tutor on LCD modules at This example run on 4 bit mode and connects to any port on a PIC with ASM sample programming for the PIC16 range. Best regards Johann
Hi, Cannot get that code to run either and not going to try and debug it. You can use Nigels LCD code from here - it is you want to fully understand lcds then have a read here
Hi, You need to follow a tutorial, here are 2 good
Hi, If you are using Pic micos then this assembly tutorial is good
Hi, You may find this tutorial helpful doing a pic to pic usart connection, use 1k series resistor in each line, then if you mistakenly connect them the wrong way round you will not damage the chips.
Have a look at this tutorial: The VREF+ and VREF- inputs are used as the voltage reference inputs for the Analog to Digital converter. i have an circuit in which the reference is attach with Vref- ... my question is that why we don't use vref + ??? may you please guide me...
Since you are a computer programmer and familiar with electronic components; I guess you can jump in to micro-controllers. As a propose, select Arduino or PIC; 79065 (For any one who wish to start programming PIC this is a great p
Hi, Have a look at this I2c tutorial
Hi, Agree with sky123 plus even the diagram and code do not match up. If you want a good Assembler / hardware tutorial this is one of the
Hi, Have a read of this tutorial , it might clarify things for
Hi, What language are you programming in ?? There are many good tutorials on the web , here are a couple of popular
Hi, In between reading that big book ,if you want something basic and practical to get you going then try these good online
As hexreader points out, received pulse widths in IR may not be the same as the transmitted ones. Thus there is usually additional coding to account for that. One method is called Manchester coding. Here are links to a series of tutorials by Nigel Goodwin. Link to all tutorials: Link to tut
Hi, You want to follow this simple 2 digit tutorial to understand how driving 7 segment works, then expand it to your needs. You might be able to reduce the chip count by using more i/o ports on the
Hi, You can use his tutorial which should easily adapt to the 84A do not give details of your dev board, but most dev boards have a 5v regulator on board, so 9v input should be ok. If you do not have a regulator onboard then t
Hi , Have a look at these lcd tutorials. Also no need to use the ORG on each subroutine. EPE FAQs & Resources PIC Tutorial* Three - LCD Modules
You are not actually putting anything on to the out pins, you are just changing their status from output to input. Check on this page and try to understand how it works from there, it should help PIC Tutorial One - LED's
Hi, There are loads of lcd tutorials around either on this site or the web. Try this site - PIC Tutorial  Three - LCD Modules

Hi, Yes we haven't heard from you for a while.. You will find full details of the software usart here PIC Tutorial* Seven - RS232 - should work fine on the 84A. If you are communicating with another pic or micro you do not need a Max232 chip if the distance is just a couple of meters.
Hi, You are using the Hardware Usarts of the chip, if you want more Usarts then simply use any standard i/o's with your own custom Software Usart. Thats how they did it before chips had Hardware Usarts built in. Details here of how to do it in Assembler, for other languages just Google. PIC
The infrared encoding I have used was pulse-width modulated. The receiver and transmitter modules did not provide any amplitude information. Here are some more in depth discussions: PIC Tutorial* Five - Infrared Communication Simple infrared d

Hi, Generally when using those RF modules you have to use some method of Addressing and Encoding otherwise your receiver gets flooded by all the other rf signals around, scope the RX output to see for yourself. If you search the forum you will find referece to the Manchester encoding method.
Hi, This tutorial should help you out - see sections 3 and 7 Nigel's PIC Tutorial Page
Rather than having someone else write all the code for you, here are a couple of pointers Delay code for PIC using this you can generate the delays you need. pic_tutorial will help with general programming. This way you will learn m

Why not just post the link Nigel Goodwins tutorial page Because I could not find it when I looked & did not have time to search.
This is a good starting place if you want to use RF Nigel's PIC Tutorial Page Look at Tutorial 12 that is about RF, I know it may be a bigger pic but you could always change it. Why not just use a transistor if your only switching 30mw that way you don't need relays which will cut the cost down
