IR Transmitter/Receiver function
- USE ALL
FEATURES OF THE GKOS ON QWERTY PC DRIVER VIA THE IR LINK TOO
New principle of operation:
Chord Value Packets (values 0 to 63)
at 10 ms intervals on the IR link indicating the GKOS keyboard status.
(No update of PIC code is needed)
GKOS IR Receiver
adds 192 to
the Chord values received and passes
them (192 to 255) on to the PC COM port at the same 10 ms intervals.
Value 192 is used for detecting this mode of operation (<192 turns
(PIC code needs to be updated, see below)
The PC Driver
software (GKOS on
QWERTY) converts the keyboard
status information (Chord values) to key presses and mouse operations
using the same routines as for QWERTY SDF/JKL entry.
(Version 0.61 up of gkosw.exe needed, see below)
All the many new features of the PC Driver software designed for
the QWERTY using SDF/JKL keys will be available on the IR link
The chord interpretation intelligence is moved to the PC Driver
Development of the concept is simpler on the PC than on the PIC
Compatibilty with the previous PIC devices is maintained.
The necessary timing used in the driver is dependent on the PC
system limitations and possible load of other software running
The PIC IR Receiver software must be upgraded. So must the PC Driver.
Software that also includes the new operation above is availble now:
- PIC hex file version gpcr102
of PIC code for the Universal
Serial GKOS PC interface
- PC Driver
version 0.63 of GKOS on
QWERTY (gkosw.exe version 0.61 up required)
The PC Driver is compatible with earlier PIC software, i.e. capable of
final KeyCodes (<>192) that have already been processed by the
PIC from Chords.
