The Xillinx chip was able to be programmed, but the interface still did not work properly.
CPLD is completely damaged. After replacing it, everything returned to normal.
I don't know why CPLD could have been damaged.
Power supply is correct, all other elements are functional.
Curiosity.

Pear, did your Genius mouse arrived? I am very exciting, if it works at you :-)

Finally it arrived yesterday.
I've got a big luck to shopping :( Two weeks of waiting :evil:
Testing at the weekend.

I can confirm. The Genius DX-110 mouse does not work with EnterMice. For now ;)
Sometimes only one button can be read. Nothing more.
I wonder what is the inaccuracy in the protocol used in this mouse.

After a few days of use, the error repeated itself. Exactly the same.
The LDO stabilizer is probably defective.
Although it provides the correct voltage during normal operation, it can cause a overvoltage pulse when switching on the power.
I will change it and check again if it will be good this time.

Not yet.
Too much work.

One puzzle solved.
Poor contact on the supply from the edge connector.
The power supply is taken from two contacts from two connectors.
Both had a weak contact :shock:
Minimal chance of such a fault.
And yet it hit.

Now I know that the control 1 (joystick) port has 5 strobe and 3 read signal, which gives 15 bits input.
Long time ago I tested the Entermice only in basic with the JOY(1) command. That time it gave me the info of the direction, not the distance.

 The question is, does the Entermice use the other input signals as well to tell a distance? I am curious because after 15 min searching I did not find any information of the protocoll it uses.

EnterMice is downward compatible to the BoxSoft protocol.

And the Boxsoft protocol comes from the MSX mouse protocol.

If you want information, first of all read the EnterMice wiki.

Once read, you can follow with how the Boxsoft mouse interface was studied and cloned.

Then, you can end with how Pear created the EnterMice .

Once done, if you still have any question, I can answer all your remaining doubts.

Ok, ok, but if you only want to know strictly that.... the data received is a relative movement from the last reading on 8bit two's complements, first X coordinate, then Y, then software buttons, then the wheel.

So the program needs to maintain the actual coordinates of the pointer and add the received relative movement, usually every 1/50 sec.

A Basic program is very slow to read the Mouse every 1/50 sec.... so the Boxoft driver can be used.

It maintains a pointer driven by interrupts, so your Basic program only needs to ask some system variables to know the coordinates, the buttons pressed and the wheel status. All is explaineded on the EnterMice wiki.
