現状Beta版という位置付けです。
This is a converter to convert PS/2 mouse to pc-9801 bus mouse using Arduino compatible board (AE-ATMEGA328-MINI) sold in Akizukidenshi, Japan.
Now it is beta version.
- Receiving PS/2 signal after sending a code to enable data reporting.
- Switching Hi-Z and zero output for XA/XB/YA/YB pulses and LR buttons. (it seems to have distortion issue of the pulse)
- Limiter for the movement. (the maximum movement is limited to 20 per 10ms due to the slow output pulse)
- Watchdog timer for checking irregular PS/2 signal.
- LED for PS/2 signal receiving. (duplicated to the serial port, so always lights up if DEBUG is defined)
- Checking for acknowledge of enabling data reporting.
- Parity checking.
