Real-time embedded systems
ATC, Acoustic Transducer Company, is a specialist British manufacturer of loudspeaker drive units and complete sound reproduction systems, including pre-amplifiers, power amplifiers and a high performance CD player.
The latest addition to their range was a CD player with integrated pre-amp and power amplifier. Shortly before launch some last minute changes were required and although ATC had all the source code, the original software design engineer was no longer available to do the work.
Having worked with M4 Electronics previously on another project, ATC asked them to take on this job as a matter of urgency so that the unit could go into production. The changes involved adding some new icons to the display, changing the way information was shown and fixing a problem with the CD player that occurred when the unit went into standby.
These changes were all completed within a day and the updated programming file sent back for in-depth testing. Having confirmed that everything now worked as it should the software could be signed off for production.
