Hello, i am working on a project to make a wireless ps2 controller and transfer data to atmega2560 board.

I have a wired ps2 controller i want to modify it and add a bluetooth module to it and trasfer data. As ps2 controller uses spi protocol to communicate is it possible to do the communication using bluetooth module hc-05?

What all modifications will be required will be required?

Like by removing the wired communication to which pins should i connect my bluetooth module tx and rx?

And how do i read the data at recieving end that is atmega2560.

I am not using any extra microcontroller only the pins of controller inside ps2 controller are to be used.

Thanks in advance.

Hi,

 

This is not going to work the way you want it to. But don't worry: All you need to make it work is a small micro controller between the PS2 controller's pins and the HC-05's pins.

The reason is that the Bluetooth module "speaks" UART and the controller speaks SPI. The conversion should not be that difficult however,  and this also has the advantage that you can define the protocol for the receiving end or leave it as it is and just pass the bytes through.

 

Maybe have a look at this http://store.curiousinventor.com...

 

Cheers

Thank you for your help but hc-05 has spi pins like miso mosi clk can't we use it for spi communication protocol?

I googled a little and it seems to me that the HC-05's SPI pins can only be used to program the module. It can't even be controlled over SPI, only UART.

The module's hardware however might be capable of doing what you want, but the SDK is not free.

So unless you want to pay a lot and learn how to program a Bluetooth SoC, you better just buy another (small) Arduino and put it into the controller.

What might be an option here is to buy an aftermarket wireless controller for the PS2. It's interface is exactly the same as the wired one, minus the cable: http://www.ebay.com/itm/18238961...

I googled "arduino playstation controller" and found this:

This is for arduino i have atmega2560 and want to code using atmel studio 7.
Is there any code for that?

What do you think an Arduino Mega has for an MPU? 

AS7 has an Arduino script importing tool.

Here is some code for handling a PS2 keyboard (this is the old kind of keyboard with the purple mini-DIN6 connector).  It has two signal pins: CLOCK and DATA.  However the protocol is not exactly either USART or SPI.    Each falling edge on the PS2 clock pin triggers a Pin-Change interrupt.  When the PS2 byte has been completely assembled (after 11 or so interrupts), the byte is parsed into a PS2 keyboard message according to whether the key is pressed or released, or if it is a key with an extended scan code.   The scan codes are then converted into ASCII or a MIDI NOTE ON/OFF message (if the PS2 keyboard is being used as a MIDI piano keyboard).

  
  //  include these lines in setup()
   pinMode(PS2_CLOCK, INPUT_PULLUP);     
   pinMode(PS2_DATA,  INPUT_PULLUP); 
   pinMode(MY_PCINT22, INPUT_PULLUP);
   pinMode(MY_PCINT23, INPUT_PULLUP);
   
   // initialize interrupt vectors for Pin_Change inputs: 
// uses volatile bool isPinChg22Active = false, isPinChg23Active = false;
// 10.2.4 pin-change interrupt control register/
   PCMSK2 = (1<<PCINT23) | (1<<PCINT22); // set to enable IRQ on pin change  [10.2.6 AVR's PD6:PD7
   PCICR  = (1<< PCIE2); // PCIE2> 1=PCI23:16  bank 2, PCIE1=1>PCI15:8 bank 1, PCIE0 1=PCI7:0 Arduino D6:D7

   
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//  Interrupt routine for PS2 clock pin going low
ISR(PCINT2_vect) {  // two active pins: MY_PCINT23=D7  MY_PCINT22=D6
    delay(20);     // pin debounce
    if ( digitalRead( MY_PCINT22) == LOW ) currentPinChg22State  = true;
    else currentPinChg22State  = false;   // PCINT22=Arduino D6::PORTD6
    if ( digitalRead( MY_PCINT23) == LOW ) currentPinChg23State  = true;
    else currentPinChg23State  = false;   // PCINT23=Arduino D7::PORTD7
 } //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have no idea of what this is and why it appeared when I clicked on the button to upload my message with included source code.

I think the 'ps2' in this instance is 'playstation 2'

But i want to code a customised board and not with a arduino Code but with normal C code as we do for other micro controller in AS7.

It is a task assigned to me.

Convert the 'Arduino' code then - most of it is probably normal C code anyways - you do realise all Arduino code is just C/C++ and a handful of standard libraries. For the most part you want to understand the method used rather than the specific code.

So like i should understand the library of arduino for ps2 and write a code for my controller?

That is one method. You could always hook a logic analyser up to a playstation 2 and a controller and reverse engineer the protocol yourself and then write code to do this. How much effort do you want to apply?

I would prefer if there is a library for AS7 for 2560 controller so that ican understand that directly and then write a code including the library.

How does that differ from using Arduino? Its the same thing whatever color you paint it.

There's a lot of PS2 projects also the protocol and the pulse reading in the net.
How hard to google it instead asking for the library here?
From that you can manage to make your own library.
You can use NRF2401 or RFM12B for that. Why chose bluetooth? You don't need very secure connection for the controller right?

By whom? This matters because if this for school or work, you should be cautious not to violate any licenses if you use libraries. If you have enough time you better just do it yourself, it's not that difficult.

I have got this task from my college where i have to connect wired ps2 controller to customised atmega 2560 board(by nex robotics) and on different led depending on data recieved.

Is it possible to convert arduino sketch to project by selecting create project fom arduino sketch option?
Please help me with this also as i have arduino code ready but want to program customised board.

Thank you

Why can't you put the arduino code on your board?

I'd get the hex file generated by the Arduino app and burn it onto your board.

Will that work on a customised board with ps2 library for arduino included and code both. I dont have a idea on that so should i just generate hex file by compiling arduino sketch and then using usb asap programmer and sinaprog app i shpuld burn code onto my board?

One more doubt while i was doing serial communication between arduino mega and my customised board i got a lag of 4 sec. Will i get the lag if burn hex file build on arduino ide on my customised board and communicate with other board?

rather than asking questions, why not actually TRY something and do some independent research. 

There's so much written about the Arduino what you stopped to consider that many other people might have just wanted to do much the same as yourself?

First question - what is the difference between an Arduino mega board and your 'custom' board? Some things to consider might be the crystal and  frequency. If these are different to the mega board, then you can alter the Arduino boards.txt file to correct this difference. Other differences might be pins things are connected to - a bit of research should enable you to figure out how this might be resolved. Arduino has its own pin numbering system, so you'll have to resolve this. All you need to do is compare the two schematics and Google the Arduino pin mapping table. Everything else just involves some thinking and a pen and paper.

 

Also, if you have a look on the forum, there are recent discussions on compiling Arduino projects in Atmel Studio 7.
