Opthalmic
Laser Control Software
Rodenstock Instrumente GmbH, Ottobrunn, Germany
 Gyrosystem
was given the task to develop software controlling the beam-delivery
section of an ophthalmic laser instrument.
PL/M
was the main language used with 8051 Assembler running on
a Siemens 80535 single chip micro controller. The system
was debugged and tested using an Intel ICE-51 emulator (with
Siemens 80535 adaptor), a Hitex-51 ICE, and Avocet and Keil
debuggers.
We
liaised with the Bavarian TÜV Safety Standards authorities
to produce a set of Standards relating to ophthalmic lasers,
which made part of the system requirements.
Conceived
and undertook a further project to improve modularity and
simplify the software creation process for generic ophthalmic
lasers. Designed using methods based on Yourdon methodology
with Intels' DCX-51 real time operating system being used
to manage tasking and events.
