i need help on my project/idea for a mcu-based module...here are my desired specs....
1. multiple output port 2. reprogrammable 3. can be used for scheduling, such as switching on/off of multiple appliances at desired (programmed ) time 4. if possible , low-cost...as much as possible.
thanks in advance...for any idea or contribution of any sort....

well, i'm currently flushed-out of ideas...especially on what type of micro should i use......all i have now is the idea of making a module.... >:) "the road to greatness is never easy, as the easy road never lead to greatness"
I suggest you have a look around and see what is available near you, and within your price range.
If you are building the "module" yourself, you'll need either a wire-proto-board (which I discourage the use of), or a prototype PCB with space for soldering components. You'll also need a soldering iron, some solder, a clamp to hold your board, etc...
The processor / microcontroller will be determined on all of the following criteria: 1. Software tools for developing code 2. Availability 3. Price 4. Functionality / Performance
Have a look at software tools, try them out, and find out what you are most comfortable with.

to Dave and jithinra: >i'll be using assembly language for the program coz i'm more familiar with that one.....:D >availability is truly a matter of topic, i'm not quiet sure of what kind of microcon is available within the country >price.as low as possible...;) >Functionaliy/performance: 1. it must have at least 8 outputs 2. it should be re-usable, especially the IC's and softwares.... 3.it must be done or could be done in at least 6-months :D

>i'll be using assembly language for the program coz i'm more familiar with that one.....:D 1.which one? means you are familiar with which architecture 8051, AVR, PIC or Freescale ? 2. Programmer and other developing tools already available to you or ...? 3. Then comes the question of availability >it must have at least 8 outputs 3. Done! but what kind of appliance you want to control ? Small DC or normal AC home appliance or Heavy duty appliances ? 4. By reusable i understand that, this module should able to plug into any appliance and should able to control it , right?

What you have asked for could be done simply and cheaply. (under $20 US).
A starter setup is a simple micro from one the standard families PIC, AVR, ATMEL, 8051 Software is free from various sources.
Choose one that can be programmed with a home made programmer. Build the project on Veroboard or similar. Add a couple of relays to switch appliances.
>4. if possible , low-cost...as much as possible. Should be "as little as possible."
>i'll be using assembly language for the program coz i'm more familiar with that one.....:D 1.which one? means you are familiar with which architecture 8051, AVR, PIC or Freescale ? =i meant that i'm familiar with assembly language and microprocessor programming in general... 2. Programmer and other developing tools already available to you or ...? =i got MASM, C++, VB 3. Then comes the question of availability =i've heard that 8051-2 are available within the country... >it must have at least 8 outputs 3. Done! but what kind of appliance you want to control ? Small DC or normal AC home appliance or Heavy duty appliances ? =small appliances, both DC and AC if possible... 4. By reusable i understand that, this module should able to plug into any appliance and should able to control it , right? =yup, plug-and-play or hot pluggable.... --Afilash "the road to greatness is never easy, as the easy road never lead to greatness"

any suggestion abt the lcd in 4 bit mode written bottom can be mailed to suji.90@gmail.com
lcd in 4 bit mode | 05 Sep : 08:44
i have only 4 bits of p2 available,the upper nibble is already in use.so,how should i write #define lcd_data ------ i can't write like 1/2(p2) or #define lcd_port P2.because this may disturb the application running on p2.4,p2.5,p2.6,p2.7 please anyone give me a suggestion

hi..i want to know whether active and passive rfid have same protocols or what?
Hi everyone. I am doing project interfacing keypad with microcontroler
i am trying with 3x4 matrix keyboard &16*2 lcd. I googled two days gone through many codes but unable to make it. Even gone through tutorial on this ite also, http://www.8051projects.net/keypad-interfacing/8051-programming.php Still i din get proper complete program. I knew its not nice to ask complete code from others. Since i am getting confused to catch the concept, can somebody give me basic assembly code to If u upload the schematic of the code will help me better to mingle with proteus, If does not have i will make it. After all i just need basic code & full information of project.. If u really want myself to design, please guide me some procedures or tips. Because for the past two days i am trying hard but end up with somewhere else.
