Engineering Introduction:
1. Important Notes
(1) Before testing This example, be sure to copy and paste the two folders in the folder "two test folders stored in the SD card root directory" into the SD root directory.
(2) first click on the song list, the song name will be recorded in the ListView control, and then can be arbitrary operation. If the song in the foldermore, first hit
meetings are slightly slower, mainly because you want to get the playback time for each song. It's quicker to open in the future, mainly to the song list dialogbox did hide and show processing,
instead of repeating the creation and deletion.
2. Function Description
(1) Support the previous, next, fast forward and rewind, common sampling rate and bitrate are supported, mono and stereo are also supported.
(2) for the audio spectrum, the amplitude spectrum and logarithmic spectral switching are supported.
(3) The Emwin task is a low priority task, the music decoding task is a high-priority task, and the two tasks communicate through task message queues and event flags.
(4) The song list dialog is modal, so the user can open this dialog box only to manipulate the dialog box, but not the main interface.
Effect:
Emwin-based Wav,mp3 soft-solution software player with a similar listening spectrum with two versions of UCOS-III and FreeRTOS
