I have built a mp3 player that uses a micro SD card for the storage media. The sd card is connected to the Teensy 4.0, audio adapter and a TFT display, ILI9488. I have included 2 files: MP3PLAYER1.ino and MP3PLAYER1.h Most of the time the SD card is recognized and everything works as expected...

I located the “software” issue. See the time in the lower left of the picture. I was blanking the old time by filling a square with the background color (black) and then writing the new time. tft.fillRect(0, 420, 250, 22, ILI9488_BLACK); Now I write the old time in black, over the displayed...

‘It’s always the last place you look!” I improved the power filtering, grounding, different SD cards, changed the buffer size to 4096 and 8192. No improvement. I removed the last software feature I added - displaying the run time of the song - FIXED! My first thought was that because I was...

The mp3 player is working very nicely - thanks to all your ideas. I do have a new problem - There is a very low / short ticking sound. It is on both the headphone and line out. On "high" volume songs - it is extremely hard to hear the tick. On soft songs it is obvious. The ticking is so soft -...

Thanks for the quick responses 1 - I will try a new SD card 3 - I have too many albums / songs to create and maintain a table - so I will forgo that feature 2 - I was just writing an explanation of the slider code and found a bug!!! I forgot to add an "else" in the code. Thank You Again for your...

Everything seems to be coming together nicely now that I have a better WMA to MP3 conversion program. Follow up questions 1 - rarely, a song will seem to "studder" for a few seconds 2 - changing the volume has an issue - using sgtl5000_1.volume() - increasing the volume works very smoothly but...

Thank you for all your suggestions I took the easy way out and downloaded another file conversion program, VLC media player. First try - it worked - so now I can begin converting all my WMAs to MP3s - again. Both my CD players have "passed on" so I am attempting to build an MP3 player for all my...

Thank You for the quick reply. I believe I have set the sample rate to 44100 and the bit rate to 192k. Still no success. It appears that I get this error from the software "ERR_MP3_FREE_BITRATE_SYNC" It comes from the file "mp2dec.h" What conversion software are you using? Thank You

I am using the Teensy 4.0 with the audio shield and FrankBs Arduino-Teensy-Codec-lib. I successfully compiled and ran the example program Mp3FilePlayer. It plays the sample mp3 files from the library and mp3 files I download, but it will not play mp3 files I create from my CDs. I am using NCH...
