MP3 Trigger V2 Adds Support for FAT32 SDHC microSD Cards
by robertsonics
Just posted MP3 Trigger V2 firmware version 2.50 on the support page. This latest version supports MP3 playback from FAT32 formatted SDHC microSD cards as well as the older FAT16 formatted SDSC cards. Also, code optimization allows for 192kbps stereo MP3 playback over a wider range of cards than before.
All the new features of version 2.40 beta are included. Please read important info about these features here.
Please note that if you’re updating an existing MP3 Trigger V2 with this new firmware, you’ll need to do so, now and in the future, with a FAT16 SDHC microSD card. This is because the resident bootloader does not support FAT32 SDHC cards, and updating the firmware does not update the bootloader. Newly manufactured MP3 Triggers will eventually come with a FAT32 capable bootloader, but your existing units don’t. So hang on to at least one FAT16 card for future updates.

Hi Jamie,
just bought an mp3 Trigger to use in an interactive artworky my wife is creating. I notice that 2.50 firmware is available but following the link on the support page leads to a ’404 error page not found’. the link to the v2.40 file works fine. Problem your end or mine?
Thanks in advance for your help,
best regards,
Nigel

Hey Jamie,
Is there any way that a hardware pin can be programmed to indicate that the player is playing a track? I would love to be able to use an interrupt to let a microcontroller know when the device has finished playing the current track instead of needing to loop looking for the serial message.
