STM CircleOS forum / CircleOS Version 3.7

Francis · 2009-03-31 15:13:10

CircleOS version 3.7 has been posted today because we are at the deadline to identify the 'reference version' for the 2009 Design Contest.
The main evolution concerns the audio capabilities that are now handled in DMA mode (much more efficient!).
A first project 'PlayWav' that demonstrate the playback functions has been also posted.

The current version is referenced as 3.7a. A second version 3.7b will be posted in the next days to fix minor bugs (some are already known). But the API (circle_api.h) will NOT be modified anymore, and your projects for the contest could used any of the 3.7x.

Version 3.7a has the following known bugs:
1. The player enters sometimes -not so frequently- an infinite loop (like a scratched record). In this situation, you have to reset your Primer by removing the battery jumper!
2. The RecWav application (to be publish in the next days too) has a poor quality sound.

Anyway, CircleOS 3.7 opens the door for future MP3 codec applications (that will be very welcome).

Please report here any bug concerning version 3.7x in order to reach a stable version as soon as possible.

New features are now reserved for version 3.8 that will not be published before the end of the 2009 Contest (July 2009).

2. The RecWav application (to be publish in the next days too) has a poor quality sound.

Probably because of gain - both amplifiers are set to maximum (20 + 22.5dB) at default. After reducing gain of second amplifier by some decibels (CR4 register) there should be no distortion of recorded sound.

Version 3.7 has been released today, and it replaces the version 3.7a.
It must be used with the new Dictaphone application that has been also posted today.
The problems with the record and play functions have been fixed. The dictaphone seems to work not too bad...

Nevertheless, any bug report would be welcome : if any major bug is discovered on this version, it will be fixed. By now, it is the official version to be used for the contest.
