arduino-ps2-mouse's Issues

Works on PS2 ball mouse but not optical PS2 mouse

Have you run across the issue where a ps2 ball mouse works great, but a ps2 optical mouse does not work. It gets stuck on the line that is check for the clock to go low [waitForClockState(LOW);]. Any ideas? Thanks

Small fix for non-AVR boards

I am running this library on an ESP32-S3. My mouse seems to work fine with operating at only 3.3V instead of 5V, so I don't need level shifters. However, it is important to activate the internal pull-up resistor in the MCU using the more modern way to get this library working. To do so, change this

void PS2Mouse::high(int pin) {
    pinMode(pin, INPUT);
    digitalWrite(pin, HIGH);
}

to

void PS2Mouse::high(int pin) {
    pinMode(pin, INPUT_PULLUP);
    digitalWrite(pin, HIGH);
}

This should be also backward-compatible to AVR boards, but needs a more recent Arduino version.

Library hanging waiting for clock to go low

I've found that the library is hanging at waitForClockState(LOW) (similar to issue #1) - the application here is for a rollerball being used as an input device (through a Teensy 3.2), it seems that the code is not initialising correctly and is just blocking forever, which is reflected in monitors - attempted to put the PS2Mouse::waitForClockState into a conditional loop and that unfreezes the rest of the .ino but then kills the PS/2 parts. Any thoughts?

Odd side effect is that the library works in its original form if the Teensy is programmed and then left plugged in - dis/reconnecting the USB seems to cause the issue to present. Thanks!
