How to update Lilypad MP3 with VS1053B firmware ?

Post by ecocat » Sun Jan 20, 2019 6:58 am

Hello,

I need to update this chipset incluided in the Lilypad MP3 of Sparkfun

I have an .ino, but how I can apply the update?

http://www.vlsi.fi/en/support/software/ ... tches.html

Sparkfun's technical service has not wanted me or knows how to tell me how to do it and the manufacturer has responded. But, given my limited knowledge, I still do not know how to apply this firmware that has very important improvements

I hit here the answer given by the manufacturer:


"There is no programmable non-volatile memory in vs1053b. There is only ROM and RAM.

Patch code is thus loaded (through the serial control interface) after each power-up or reset. If the Lilypad already supports loading patches, there is probably a file vs1053b-patches.plg (or vs1053b-patches.c) somewhere in its firmware project. You should only need to replace the file with a newer version.

(If not, then see the upload routine in the file itself (e.g. vs1053b-patches.plg). It only needs an external SCI register write function. Also see the microcontroller examples elsewhere in the forum.)"


Thanks!
