Did you ever wonder is there a way that you can develop a cool and sophisticated Soundwave MP3, where the idea is coming from the Transformer cartoons?
In this project, you’ll learn how to exercise the ATA interface and access files using the FAT, and the proper ways to access the PCF8574 and MAS3587F through the I2C bus! This means, after the accomplishment of this project, you’ll have a very good understanding of ATA, I2C, FAT and MP3 files.
During the development of this project, you might found out that the sometimes, the cables can be unreliable, where you could be facing the problem with the LCD all day long, but it ended up being a cable where adjacent pins had shorted together!
One more thing, if you still an amateur in the FAT field, then you should know something about it! Remember that the location of the root directory is NOT to be stored in the data portion pointed to by the FAT table, and the root directory is comes directly AFTER the FAT, and not BEFORE the data segment!
Lastly, hope you’re able to learn and enjoys the fun moment of this interesting project!
