I've just started playing with Android Things and noticed that I could not find anything about PS/2 support in its library. I am trying to hook up a TPM754 trackpoint module to my RPI3 so that I can possibly write a drive so I can use it.

As far as I am aware, the TPM uses PS/2 to communicate. Is there a way to do that in Android Things? I am not so experienced in programming a hardware so I do not see the overall steps I need to take to achieve what I want to do. So, I am learning as I go and would really appreciate if someone could give me a big picture.

Can someone give me pointers?

Seems easiest way is to use hardware adapters PS/2 to USB (like that), or if TPM754 didn't works via USB - pair of connectors PS/2 to RS-232 (like that) and RS-232 to UART (like that) (also PS/2 to UART adapters exists, but seems they more expensive), or more exotic converters (e.g. PS/2 to I2C).

  • Almost none of these paths are likely to work, unless the peripheral itself is dual-mode PS2/USB. Otherwise an *active* translating adapter is required. The suggestions to go by way of RS232 are utterly unworkable nonsense - as in the original, your are confusing connector types with electrical and application protocols, when they are actually completely distinct subjects. – Chris Stratton Oct 16 '19 at 23:40
