Greetings everyone
I have worked on 8051(atmel), processor.
in those processors we need to dump codes using a dumper.
The question is how do we need to dump the code in the raspberry pi.
My project is to control a small bulb or an LED just to switch it on and off,
and if i need to do that wirelessly how do i do that. i mean if i give an input using my mobile(android) i want that light to be switched off.
P.S : i am using WI-FI.
Php?
Android app or web server -> php request -> MySQL -> c or python -> GPIO -> resistor -> transistor ?
That's one way to do it.

No vinodmadhu6, the CPU on the Raspberry Pi is nothing like the Atmel AVR chips, you can program using a range of modern programming languages.
I'd say Python would be a good way to go, especially if AVR has been your main experience of programming up until now, as it is an easier language to learn
An 8 bit 8051 it definitely isn't! It is a full 32 bit ARM processor capable of running various flavours of Linux.
It is possible to pull the voltages high and low on the pins on the header of the main board, referred to as the GPIO.
Have a read of this:-

Hello,
WebIOPi isn't compatible with Raspberry Pi 2.
Is there another way to connect GPIO on RPi2 via web?
Depending on how sophisticated you want that control to be, it's not hard to achieve from scratch. Here's a complete example of toggling a few GPIO pins from the web: https://github.com/pimoroni/Raspberry-Pi-Web-RGB
Or if you're dead set on using WebIOPi there seem to be patches for Pi 2 support here: https://github.com/acrobotic/Ai_Demos_RPi/tree/master/demos/gpio
They look legitimate, since they include the shifted memory address for the Pi 2 GPIO ( https://github.com/acrobotic/Ai_Dem.../webiopi_raspberry_pi_2_cpu_support.patch#L45 ), but I haven't tried applying them.
I was doing my first raspberry pi electronic project. I choosed the adafruits Google docs logging project for a start. The project was a success and I obtained a complete output. My problem is , when I looked into the python program provided by adafruit (got it from github) it is calling other small programs. So I looked one of the called programs and it again calls other program.
I want to write a complete program that includes all the necessary things ie a stand alone version.
I want to write it in python 2. Also use a gpio pin 5. My model of pi is raspberry pi 2 model b.
I don't know whether I can include driver in my program. But if it is possible , I also want to include the driver too, please help me.
Hi,
I want to create a custom keyboard using a Raspberry Pi. I have a very limited knowledge in Hardware and Electronics. But I know how to code in Java/Python/C/C++ very well.
The keyboard should be able to store every text file that I type into it. That is, it should have an internal storage. Additionally, it should be able to connect to any Android/iOS/Windows device like smartphone, tablet etc, so that all text content typed is shown in the required device in real time. All text typed should also provide real time audio feedback. As a trial I have created 2 prototypes where one is running on Raspberry Pi with internal storage with real time audio feedback. And another device which runs on Arduino Leonardo to connect to hand-held devices. But for the final product we need to create a single device with both features in built.
In summary, here are my requirements:
Audio feedback: Recites every word I type in real time through headphone jack.
Internal storage: The keyboard should have an internal storage slot to store what I type.
Portable: It should be easy and light to carry around.
Cost effective: It should use cost effective solutions/materials.
Plug-N-Play: Connect to any Android/iOS/Windows device like smartphone, tablet etc. and act as external keyboard.
Battery Life: The keyboard should have a reasonable battery life.
Questions:
Which model of the Raspberry Pi should I use to create the keyboard. It needs to be an most inexpensive model which can satisfy all the above requirements. Is it possible to use the Raspberry Pi Zero and then add any required modules?
We need a USB HID + Linux version that runs Python or any other distribution with text to speech. Currently, for a prototype, we are using Arduino Leonardo for USB HID and Raspberry Pi (B+ Model) for Text to Speech conversion (we are using Espeak at the moment).
I have a custom design for the keyboard but the ports of the raspberry pi don’t align with the custom design. What options do I have here? Example: Assume, I want the headphone jack to be on the side of the keyboard. But the headphone jack is placed at the bottom in the raspberry pi.
How to create the outer casing for the product? Again, I want to use only cost effective material, yet it should look as professional as possible.
Thanks!!!!!!!!!!!!!

Did u complete it.if yes plz ping me

Plz ping me i want to know about your project
I love raspberry pi and I made many programs in Python. One of them is a cool GPIO robot controlling program. But I want to use my pi without any display and I also want my pi to run that specific program when it is powered.
I mean without booting all that Raspbian os and all that.
Is that possible.
If yes then please let me know
Thanks.
Hi! Yes, you could burn the lite version of raspbian on your sdcard. The lite version just has the basic stuff without "fancy" extras! Once booted up, write or copy your script to your pi, to a location you remember and start it at boot with the correct entry in the rc.local file!
Example line: python /home/pi/example_dir/YOUR_SCRIPT.py
I hope i could help!
