The first test failed :(
I do not know yet, what I'm doing wrong.
The mouse pointer "escapes" to the top-left corner of the screen.

In the Arduino source I seen that are not sent the delta values, only after each mouse reading is summed delta and send the sum.
I was a little confused.

I can say you about the problems I had adapting the Arduino project to the Enterprise.

It uses an input-output register for the seven signals(four directions+two physical buttons+strobe). Then, after every host reading the MCU must mask the output lines. If not, the mouse pointer goes up-left because the host reads data of the last reading.

But congratulations, it means that the Enterprise is reading something. The pointer goes to the opposite when no mouse connected...

The Arduino script is very well made(even if the author says otherwise). Don't mess up with delta or other variables. Your problem has to be the reading phase.

At the end I 've only changed the polarity of the signals on the script and all begin to work.

I think, I know. All the data bits are negated!
But it's I'll check tomorrow.

If further tests come out better than today, and I counted correctly, it should EnterMice in the current configuration to work correctly even with the EP CPU clocked at 10 MHz. Measurements and calculations came out to me that reading occurs after 26 us, and interrupt service until set the data I managed to fit in 23 us (MCU clocked at 12MHz).
Code: ASM

  2.                                         ; tacts limit 56 @12MHz (112 @24MHz)

I stare at the code, and I just found a stupid mistake in the 11th line :)

On the Arduino script I modified that lines:


void sendMSX(char c)
// Optimized for Atmel328
// NOTE: Fixed pins!
{
while (digitalRead(JoyPin8)==LOW) {if (millis()>time) return;};
DDRD = ((DDRD & 195)|((~ (c>>2)) & 60));
while (digitalRead(JoyPin8)==HIGH) {if (millis()>time) return;};
DDRD = ((DDRD & 195)|((~ (c<<2)) & 60));
}

To:


void sendMSX(char c)
// Optimized for Atmel328
// NOTE: Fixed pins!
{
while (digitalRead(JoyPin8)==HIGH) {if (millis()>time) return;};
DDRD = ((DDRD & 195)|((~ (c>>2)) & 60));
while (digitalRead(JoyPin8)==LOW) {if (millis()>time) return;};
DDRD = ((DDRD & 195)|((~ (c<<2)) & 60));
}


And:

void JoyHigh()
// Optimized for Atmel328
// NOTE: Fixed pins!
{
     DDRD=(DDRD | 195);
}

To:

void JoyHigh()
// Optimized for Atmel328
// NOTE: Fixed pins!
{
     DDRD=(DDRD | 0xC3);
}

And it started to work properly.

Today was much better :)
Tested with the original driver MOUSE.XR (not yet modified) in BoxSoft compatible mode.
Data bits are not inverted. There was only one mistake in the interrupt service :)
There are a few trinkets to refine.

The mouse can be disconnected during operation without shutting down the computer.
After reconnecting is ready for operation within approx. 2 seconds :)
You can also connect another mouse, and its type will be identified  (with the wheel or not).

Remained also to do a joystick mode. I still have to think about how he will exactly work, but compared to what already I did this little thing :)

All the PCBs already assembled. I have yet to mount edge connectors.
I also found and corrected a minor error in the PLD logic.

I like too. I've been talking two years about mice and interfaces without a "video-proof". I should have done long ago one about my works....

Is a good trick that the Entermice can rearm the mouse like USB does. I remember resetting the PC as, if the PS/2 connector was moved,  you had to shut-off  and re-start the computer to have again a working mouse.

To watch the pointer moving on a different Enterprise than mine shakes something inside me....

It is too nice to be true ... :)

I made a joystick emulation mode service on the model of Arduino code.
On the emulator it looks good.
Resolution (actually sensitivity) is set on dipswitch.
Today, I no longer have time to check the code on the target device.

Some tips for sensitivy testing:
-Simcity, it is with the original Neos joy mode litle slow, need higher sensitivy setting
-Krakout, it is great with the original Neos. More better playing than the real joy!

I think, better put him the links as he may not know where to look for the games.

His time is precious for us...

I have a better idea. I'll send to Zozo ready EnterMice for test and checks itself :)
I have the second tester. Do you agree Zozo ?
