Give it a try. U ll come and thank me later. If they don't sell the PIC, they will tell u where to buy them.

cogitoErgo:
ur suggestion may work fo transistors, OpAmps, TTLs etc but for microcontrollers and their programmers, I doubt it? But its still a good advice, I will try it!

@Otuabaroku:
I don't understand wot u meant by 'Technological Acceptable'.
Can u expantiate more on that!

@naira.......
This particular project am talking about, I did it as a school project. But am planning to modify it and deploy it for public use.
I ll change the hyperterminal part with a VB application.
And also declare many ports (instead of just single port) to give room for more controls.
And also doing a project on wireless demobilizer and tracker.
It will involve PIC, gsm module and gps module. Though this product is already in the market, I still want to design and market it in east. As there are still many cases of car theft and kidnapping going on there!

@nairaface interfacing micro controller with hyperterminal is a little tricky. It took me several trial and errors before I got.
But u ve to take note of the following
-hyperterminal transmit only characters and can receive a string character.
-the characters are ascii characters,so wot ever u are sending to the micro controller, u ve to look it up in ascii table to determine the actual value u re sending to the micro controller.
-also u ve to make sure the baudrate u set in ur micro controller is same with that of the hyperterminal.
If u take note of these 3 types, u won't ve problem communicating with d ucontroller through the hyperterminal.

Nairaface: Hi there, did you do this for a school project, or a potential business, or on the job?


I have done embedded sys to control: radars, vending machine, security sys, and more, both in school and on the job. I'm currently looking to go solo once I get some logistics in place. I once needed to interface with an hyper terminal and had quiite a number of hiccups, having never done it.

Any casualty or rather how many casualties pls.

The trick is this; meet those road side electronics repairers, ask them where they buy their components. From there, u can get more information on where to get d rest of the components.
Just give it a try!

cogitoErgo:
thanks frend, I had discused somethng like this wit some people here on NL b4, bt d fear fear of sendng mony to some unknown persons and they did not realy said they used PIC!
Im actualy n Jos, but I do ocasionaly come to Ilorin.
culd u posbly help in getng some of materials?

I don't know y u find it difficult to believe in the implementation of this my project. U also argued my projects might not work wen tested against many inputs.
But I find it very difficult to understand y u so much believe that this my project will not work wen tested.
Anybody conversant with micro controllers and c programming will the that the above project am describing is not a big deal.
Now if I may ask, wots a big deal in this project.
Is it the HYPERTERMINAL part or the C Program or the implementation of the WIRELESS.
If u may know, the implementation of the wireless involves using RF module(Rs232 compliance) which is available every where to implement the wireless.
Or is it the control part of it. Ok by connecting a relay to PORTs in micro controller, common sense will tell u that as soon as the port is set(ON) any device connected to the relay is automatically ON, since a relay is an electrical switch.
And also the internet part of it; though a PIC with networking properties is not yet fully available in d naija market. So I now used a REMOTE access to a local computer. The local computer will have my HYPERTERMINAL and serial comm with RF module properly connected. So if I use Router port forwarding and REMOTE DESKTOP technology, I can access the the local computer from the internet with any computer that uses window. And that means I can equally access the hyperterminal program from where I can READ switches and TURN ON or TURN OFF these switches as I may choose.
So wots the big deal in this project!

U mean maulag where they give out degree certificates to runs girls(prostitu.tes) and yahoo boys...................

Embedded system is any system that uses micro controller to perform a specific tasks. And unlike micro processors, most task micro controllers perform are usually CONTROL OPERATIONS.
So the system I was describing is a system that can be used to wireless CONTROL(turn off and turn on) electrical devices(switches).

Wots ur reason. Is it becos everyone is into programming?

Maleeq:
In Nigeria, I would say there is more market for programming than embedded systems.

I was just joking wen I said 'am d king here'. And wot I really meant is that nobody is contributing.
And to what u added, u can't start teaching wot embedded system is all about after graduating from computer engineering after 5 years.
And the pproject I was describing below is a project I ve designed already and its working. I ve done several projects on embedded system and they are all working fine.

Otuabaroku: Hi Dondbuzor, it seems you do not fully understand what is meant by embedded systems. It is a computer system designed to perform one or a few dedicated functions often with real-time computing constraints. If likened it to what you have done, you will find out that you are doing a different thing.
Again, haven categorized your project as one of control systems project. I was expecting a thorough design, implementation and testing.You have not achieved that from your description and explanation so far. Don't you think it will be better you do that before claiming King of Embedded systems.

For spewing this trash, u ve won d most usele.ss poster of the day. Ask seun for ur prize.
@topic this is complete dictatorship at the highest level. Selling people property for disobeying road traffic laws.
The punishment is even worse than that for arm roBbery.
Oga fashola, better watch ur back cos am com'n after u!

zeefa: First thing first! Why must you violet d law in d first place! Fashola Govt are ONLY looking for ways nigerians could get those rules in2 their head n start doing something right when it comes to safety in our road! Please tell me! This actions is suppose to b taken by FRSC boss in d country! But they are just clueless human being who feels changing the plate numbers is the solution to the reckless driving in the country. After driving 4 then years in nigeria, I kw ao much it cost me to get a drivers license in the middle east! Cos their police are working and trying to at least set a gud mind set for every drivers on the road! Ensuring they understand d Do's n don't's ! I commend fashola Govt for a job well done. If auctioning of seized trucks wld make ppu seat tight then so be it. If am caught in the act, I don't mind to forfeit my car cos it wl serve as a lesson which I won't try 2 repeat again! Let who have ears hear! Eko oni baje o! To ba si baje, awa eyan na la wa nibe! Lo ba tan!

But I no see d lappy wee him de use de update him fb wall. Abi him don sellam due to worsening economic situation in naija.
Though oFfice looks nice and simple. Goodluck to naija

Pls I need an answer. Embedded systems and programming which one has more opportunities(profitability) in nigeria.
With reasons plz

@corgitoErgo u can aslo check out dis thread

on programming section to see how provided a detailed analysis on how I constructed one of my design.
https://www.nairaland.com/1048606/embedded-systems

U first have to know and understand d circuit components u need, the sensor type u ll need to measure temp and press. The type of micro controller. Even though u might want PIC, u ll still have to decide the type of PIC u ll need (there are over 50 types of pic). I personally I always choose PIC16f887 bc I ve d materials, examples and compiler for the pic.
And since u ll be using a PIC, u ll also need MikroeC compiler(google it).
And u also want ur device to send information(communicate) with a pc (whether wired or wireless), ur project will also involve serial port communication.
NB all the components u need are available in naija. It depends on where u stay.

I ve done similar project beforen goodluck to u.

cogitoErgo:
I am nt a programer nor an engineer bt I m a scientist! and Im interestd in the PIC for a project Im conceivng currently. Im particulaly happy u have implemented sometng wit PIC and I wuld like to have the details of how u source all ur materials in Niaja (I mean all, PIC module, PIC Programmer, the compiler and the sensors). Im woking on sometng that culd sense atmospheric parameters(temperature, pressure, etc) display and store it for onward transfer into a laptop for further analysis!

Call me on 0803buzor

@op u re a disgrace to computer students. @topic am suggesting writing a project with d topic 'how to sleep late and wake up early'

It seems am d only one here!
It seems members of dis programming forum know very little about embedded systems and that's y they are not contributing.
Hope am not d king here!

@maleeq this is wot am thinking, since most IT gurus are into programming; this simply means that d man power in embedded systems is not enough for d teeming population in naija.
I simply mean that there is less competition in embedded system and thereby making it more profitable.
Wot do u think, embedded systems and programming, which one is more profitable?

Maleeq:
Like the majority, I deviated into full time programming. I've still got the flare for embedded systems but not the time to really pursue it (guess i am a bit lazy).

So madu is no longer coming back to continue his story.
Congrats to d always unbelieving,too hard-to convince nlers. As u guys have successfully pursued that little and innocent girl.


Ooooh ma world, that girl is little but not innocent. She don even sabi pass me!

Wots rapsberry pi?

ositadima1: Guy it was an hypotesis ooo, my interest now is in d raspberry pi, i want this thing but the dont ship to nigeria.

raspberry piraspberry pi

Ve being using 'lion transformer'. It makes ur window look like mac ox. But I ll give dis one a try soon.
Oh I forgot, window 8 tile is hitting d market soon.

@ositadimma ve u found d sensor u re going to use for dis project. So how do u implement ur system to always pump water once the water level is low and there Is power supply

The PC part
The PC will be where the control will be taking place.
I used hyperterminal for the pc but when I ll deploy d project for public use, am gonna use VB application.
Now this is how it works on d pc side.....
The hyper terminal is a window application that allows one to send and receive character(s) in the serial port.
A serial port is a particular port on ur pc used for serial communication. Though not all pc has inbuild serial port but urs don't have, u can get a serial port adapter.
Now on my hyper terminal, I can send those particular characters I defined in d C program in burned into d embedded system.
I used nos 1 to 8 to on, then letter a to g to off etc. And also to know the switches that are on or off, I used r. So any time I type r, d micro controller checks d port(relay is connected to d ports) that is on and off and send the information back to me.
I labelled d ports like this-
Port D.0 = switch 0
Port D.1 = switch 1
......
Port D.7 = switch 7.

So I can have something like this as a response from d micro controller-
Switch 1 is on, switch2 is on, switch3 is off etc to switch7.
In real world application, the switch ll be replaced by d name of electrical device that is connected to d relay. Eg is TV, Fridge, etc.



To be contd.

@ositadimma
If I give u d complete circuit diagram and circuit components, d C program for d controller, can u build it urself?
Kk I les I forgot, u might face challenge in burning d hex file into d micro controller. But if u can see who can do that one for u, then u can get d rest of d components as I ll show u and connect it together then u are good to go!

I ll soon post d design, implementation and testing of ma project in ma next post. Just relax.......

Otuabaroku: ^ @Dondbuzor. You see, that is the biggest challenge we face in this country to develop technologically. Always quick to make money. Have you wondered why most serious organization are not taken us seriously. If you have done your first project professionally. I bet you don't need to embark on the second project in order to make the money you are looking for.

Mind you connecting the materials(used for your project) you have listed and writing a code to carry out action when a particular port of the serial port is set on or off is not good enough. I was expecting you to give brief description of your design, implementation and testing. In that way, your project would be tested for its rigorous technical input and also determine its business prospect.

In terms of marketing, if you convince visitors to this thread a lone about your project, you don't need to worry about marketing to naija banks.

That's my two cent or one dollar.

ositadima1: @Dondbuzor dats dat is true, but are u fully into these projects, or part time? Is there a thriving market for this kind of projects in nija? Where i stay they have this motor dat pumps water into a tank, the wahala is dat u have to switch it on manually when ever there is light, and of when it feels up, a controller can automate this chore

All u need to do dis project is a sensor that can measure water level and a micro controller. Its very simple and straight forward.

I have one other project am working on. When am through, I ll give d 2 projects to a bank to market.
Just discovered dis from a friend. A particular naija bank markets his ICT projects.

@ostadimma how I do my thing is that I first chose a particular compiler that has enough library for a a particular ucontroller. With that, I free my self of studying the architecture and instruction set of that particular micro controller. So with the lib function in a compiler, I can know wot a particular micro controller is capable of.

@maleeq why do u chose to do embedded systems as a hobby. Does it mean u can't see the large market available for embedded systems in naija. Y am saying is because most of computer gurus I know are all into programming, web development, app development etc. But hardly do u meet anyone into embedded systems.

Its not just machine code. C can be used as well. I would ve loved to discuss with ppl who ve done one project or another in embedded systems.

ositadima1: I am intersted, i like hacks, but can u get all this components in nija? When i was in skull people use to code 8051 chips to desplay signs on led dashboar, it was machine code, good if want to understan how controllers work at d lowest level
