Serial Mouse Converter
|
||||
======================
|
||||
This makes old serial mouse into modern USB one.
|
||||
|
||||
Tested by:
|
||||
- Microsoft green-eyed mouse
|
||||
- DELL mouse can work with DTR only.
|
||||
|
||||
|
||||
Pinout
|
||||
------
|
||||
|
||||
DE-9 DB-25 DTE DCE Description
|
||||
----------------------------------------------------------------
|
||||
2 3 RXD TXD data from mouse
|
||||
3 2 TXD RXD used by mouse as power source?
|
||||
4 20 DTR DSR used by mouse as power source
|
||||
5 7 GND GND
|
||||
7 4 RTS CTS used by mouse as power source
|
||||
*DTE=Converter, DCE=Mouse
|
||||
|
||||
|
||||
|
||||
## RS-232 Driver
|
||||
Microsoft mouse seems to need higher voltage for power source.
|
||||
SP3232E outputs only +-6V at charge pump output and didn't work.
|
||||
ADM232A works for both Microsoft and DELL.
|
||||
|
||||
Microsoft green-eyed mouse requires both while DELL mouse can work with DTR only.
|
||||
|
||||
|
||||
## Wiring
|
||||
Mouse RXD, TXD, DTR and RTS should be wired to RS-232 driver.
|
||||
Wire up RS-232 driver charge pump output V+ to DTR and RTS for power source purpose.
|
||||
|
||||
Connect Mouse TXD to AVR PD2(RXD) *through* RS-232 driver for mouse data.
|
||||
|
||||
|
||||
|
||||
UART Setting
|
||||
------------
|
||||
defined in config.h.
|
||||
|
||||
### Microsoft serial mouse
|
||||
1200 baud, 7-bit data, no parity, 1-bit stop, lsb-first
|
||||
|
||||
### MouseSystems
|
||||
1200 baud, 8-bit data, no parity, 1-bit stop, lsb-first(Not tested)
