Problem when combining TVout library and PS2Keyboard library

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
set up TVout, this step works, I am able to run the examples, and they work fine
2.
Set up PS2keyboard library, this works, I ran teh example and it works fine.
3.
Mix TVout and PS2Keyboard, when I did this, I got problems.
 I went ahead and combined TVout and PS2Keyboard libraries, but they seem to clash with each other, they work,  but weird things happen  on the TV   there is a glitch whenever I press a key, and on the keyboard there is sometimes wrong keystrokes detected... they both work well indivisually here is my combined code http://pastebin.com/caVhZQcT

What is the expected output? What do you see instead?
each key I type on the keyboard should just appear on the screen,  but instead 
sometimes wrong characters appear. and also there is a glitch on the TV 
everytime I press a key.    also, since I am logging everything to the serial 
port, I can see that the PS2Keyboard library is failing to recognize the 
characters when mixed with TVout.

What version of the product are you using? On what operating system?

I am using TVoutBeta1 uploaded to arduino uno  from a windows computer

Please provide any additional information below.

I tried stopping timers when a key is pressed, and enabling them after it was 
released. but still the input is currupted, I wouldnt really care much if there 
is a minor glitch in video temprarily, but I want to be able to get information 
from the keyboard. here is the code I tried in the PS2Keyboard library:

void ps2interrupt(void)
{
    //stop interrupts 
    cli();

    static uint8_t bitcount=0;
    static uint8_t incoming=0;
    static uint32_t prev_ms=0;
    uint32_t now_ms;
    uint8_t n, val;

    val = digitalRead(PollPS2_DataPin);
    now_ms = millis();
    if (now_ms - prev_ms > 250) {
        bitcount = 0;
        incoming = 0;
    }
    prev_ms = now_ms;
    n = bitcount - 1;
    if (n <= 7) {
        incoming |= (val << n);
    }
    bitcount++;
    if (bitcount == 11) {
        uint8_t i = head + 1;
        if (i >= BUFFER_SIZE) i = 0;
        if (i != tail) {
            buffer[i] = incoming;
            head = i;
        }
        bitcount = 0;
        incoming = 0;
    }
    //start interrupts
    sei();
}

Hello, 

I am using both the libraries and my sketch seams to work correctly.

The only issue I found is the glitch when pressing a key.
I've also observed than pressing continuously a key, the glitching phenomenon 
disappears.

I don't know if it's your case, but few days ago in one of mine sketches, the 
PS2 Keyboard library didn't recognize correctly a key due to the too high 
memory allocation (using a matrix)...
I hope this could be helpful... 

Now I will try to solve the glitching issue...

I have already found a fix to the problem.  It was to use pollserial to get 
data from the keyboard. It works perfectly.  I can send you the libraries and 
sketch if you want

Ok! If you send me libraries and sketch I will appreciate!

Ok, here is the library on the attached files

alos, I thought you might be interested in the BASIC interpreter for
arduino I made
https://github.com/amigojapan/Interactive-Arduino-Basic-Interpreter
 I will eventually figure out a way to do something to get enbough ram to
run both the BASIC intepreter AND all TV out at the same time to make a
retro computer, I think I may store the programs in progmem

also you might want to add as an example of TV out my video of this True
Serial Terminal I made that actually connects to a linux computer and can
control it thru a serial port. it is the latest video of my channel

Thank you! I am just trying your Basic Interpreter!

I'm sorry but I can't see your attachment... :(

Ok, later when I get time I will upload it to github and send you the link or 
something

Received! 

I will try it later and let you know!

Thank you!

Hi, I have another question. The ore Beta 1.0 version of TV out seemed to have 
a pause() function which "returns full CPU power". Is there an equivalent in 
the new versions?

does anyone have the attachment since the op was kind enough to place it on a 
crap server which no longer has the file?

Thanks

I have it on my home computer but I won't have access to it for a week or so

Thats fine if you can repost it when you get back

Thanks

OK, I have heard some people on the mailing list asking about the library to 
use PS2keyboard together with TVout, here is a link to it
