Quozl's Open Source Work
Technical Aid to the Disabled Projects
Quozl works as a technical volunteer for Custom Designed Aids (CDA)
within Technical Aid to the Disabled (TAD). TAD constructs devices for people
with disabilities to make their life easier. TAD is a registered charity
(CFN 10944) and voluntary organisation. Quozl's membership ID is P5497.
Quozl was involved in several projects, often with the aid of other
volunteers. PIC Microcontrollers were used in many of the projects to
reduce cost and complexity of the design. Documentation and
many pictures for some of the projects are here.

The Linux operating system was used during development of these
projects. xcircuit was used for schematic diagrams, emacs was used
for source code editing, CVS was used for revision control, gpasm for
assembly of the PIC code, gpsim for simulation testing, and picprg for
programming the chips. Some of the photographs here have been
processed with GIMP.
Quozl has contributed changes to gpasm for the PIC 12C509 processor, and these
have been integrated into the gpasm source code.
Quozl has adjusted the GNU Emacs asm-mode.el
to provide syntax colour highlighting for PIC assembly source.
