How do I read Mickeys?

[CarnMeynen]

Hi Folks

I am developing a serial port encoder for our telescope here in Swansea. It uses the two wheels of mouse, one connected to the declination axis and the other connected to the right ascension axis. The mechanism is connected to the serial port.

The encoder is a plug in for Cartes de Ciel, written in Delphi. I would like to know how to read the encoder Mickeys. That is, ths single units of movement of each wheel coming in through the serial port. Remember this is Windows, not DOS so reading the hardware is frowned upon but documentation on this matter is pretty sparse.

Thanks in advance.

you should be able to grab yourself a comms vcl and capture the info comming from the mouse.

I can recommend asyncpro from turbopower or cportlib.

here's the link for asyncpro (it's opensource)

http://sourceforge.net/projects/tpapro

and for cportlib:

http://sourceforge.net/projects/comport/

Hi

I don't know what I'm supposed to do with Asyncpro, and the comport component is fine but it is designed to read data from a serial device like a modem.

How can I use it to read a mouse?

Cport will allow you to capture whatever data stream appears on the COM port, not just a modem.
You need to know the protocol (data structure) the comm speed and the handshaking rules for whatever device it is that you are trying to 'read'.
