Commercial software projects

Michael started his working life as a software engineer working on major projects with million+ LOC. As his career has moved into test and leadership, software development reduced considerably but never quite disappeared.

Through Compute Thing Ltd the balance of work has shifted back to more hands-on development.

'Connected Care' monitoring and alarm system for the home

Although engaged with the client to lead the acceptance of a 3rd party product, difficulties in the project required a much more proactive and hands-on approach.

Michael made a number of significant interventions in the software development that included

  • Establishing a method to retrieve debug information from devices that had locked up.
  • Challenging developer understanding of boot-loader operation
  • Proposing solutions for key software architecture issues
  • Leading bug reviews and providing expert knowledge to management team.

Motorola mobile radio software development

CQM6000

CQM6000

I maintained and enhanced firmware for 20+ variants of the CQM6000 product range. This included major features and bug fixes in MCS51 assembler

As described on the Storno site the CQM6000 was undoubtably the most versatile radio Storno produced.

MX3000 & GP300

I developed customer specific software for the MX3000 and GP300 radio models in 68HC11 assembler from requirements trhough to code and test. The MX3000 was particularly interesting to work on with a second processor managing the UI. The UI was implemented as interpreted virtual machine programmed with its own byte-codes or assembly language (an advanced approach in its day). Customer solutions often required coding for the 2 real processors, the VM and PC based service software.

Mandown/deadman module

I developed all firmware from reset vector upwards for an additional processor module that fitted into an extended version of the MX3000. This module contained mercury switches which triggered the radio to make an emergency call if there was no movement or the radio was tilted.

The Crypto Museum has a good description of the module and further photos.
