/**
* @fn playSpecFile
* @brief Play file of the specific path
* @return Boolean type, the result of operation
* @retval true The setting succeeded
* @retval false Setting failed
*/
bool playSpecFile(String str);
what is the specific path?
please explain in detail.
I changed the name of the music file . like 1, 2, 3, 4, 5…
playSpecFile("1"); → play 1.mp3
playSpecFile("2"); → play 1.mp3
playSpecFile("3"); → play 1.mp3
but it played only one song.
Q2.
/**
* @fn playFileNum
* @brief Play the file of specific number, the numbers are arranged according to the sequences the files copied into the U-disk
* @param num file number, can be obtained by getCurFileNumber()
* @return Boolean type, the result of operation
* @retval true The setting succeeded
* @retval false Setting failed
*/
bool playFileNum(int16_t num);
The numbers are arranged according to the sequences the files copied into the U-disk
I copied the file in order 1,2,3,4,5,6,7…
but the file number is different 1,2,5,7,9,11,12…
how it happened?
Q3.
I just want to play the music that I want in order
what is the best way to do it?
Hi
Could you please rename your song like this?
The function playSpecFile means The designated path, like D:\mp3\0001.mp3
About the file number, it can be influenced by the property of the file itself.
I have asked the product manager for more detial and will come back to you soon.
