can i reprogram my cromecast 2 with Rockchip batch tools?

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.
Hello everyone, I'm new here . I went from an Arduino raspberry pi greek 2 .
The material and this :
- Raspberry PI 2
- Datalogic Magellan 1100i
- Relay Module
- Form RS 232
What I do and this would affect :
By using the QRCode barcode reader or I should be able
whether a valid ë ( By comparison with the code format string or
Another with qrcode ) . If valid then Ê Activate the relay connected ( Should Be Very Simple ) .
Where do I start ?
Dove Can I find the Instructions That helps me create and this kind of " Activator relay via barcode scanner or qrcode ? ) .
REMAINING are in the old RS232 why are so many years What I use with Arduino and I'd like instead of USB .
Thank you
Cristian
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!
