MP3 Development Board

sku: DEV-08603

Description: Have you ever wanted to create your own MP3 player? The MP3 Development Board combines a thick set of technologies to give you the most options available. It's got a color screen, accelerometer for menu navigation, 1gig of storage (user upgradable), USB mass storage, as well as a built-in FM transmitter (for your car!). We give you the basic software functions, you make the player your own. Headphones not included.

The MP3 Development Board uses the SparkFun USB bootloader. This bootloader allows you to compile firmware on your local workstation, then copy that firmware file onto the unit like it was a removable flash drive. When the unit resets, the firmware is automatically copied from the micro-SD card to the internal flash of the ARM7. This system greatly increases the speed at which the firmware can be flashed to the unit.

Features:

LPC2148 ARM7 from NXP
MMA7260 Triple Axis Accelerometer
microSD Socket
1gig microSD card included
Tri-color Status LED
Standard 3.5mm audio jack (no headphones included)
miniUSB connection
3-way Navigation Switch
128x128 pixel Color Graphic LCD
NS73M FM Transmitter
Lithium Polymer battery (1000mAh)
Built in LiPo charger via USB

After compiling the example firmware, the display doesn't show anything, stays blueish. I'me using winarm as recommended. Got no errors during compile. How to get the display working? As anyone tryed this?

What is the DAC like? What is the audio quality like?

I am having the same issue as LVicente is having where I updated to the zip file version of FW.SFE and the display stops working however it still plays MP3's. I also noticed the the PCB is slightly different from the User Manual Figure 1. The most notable difference is the programming header moved and the debug header has been removed. I was hoping there would be a firmware update on this site.

Can you run the LPC2148 at higher than 12MHz and still get USB?

I have mine working and the gcc-arm toolchain is set up under Ubuntu and is working in Netbeans (I don't like Eclipse).

I had the same screen not working issue; I had to mess with the connector a bit to get it to work.

Audio quality isn't bad at all. With the default software it reset on me a couple times and it glitches every now and again, providing more stimulus to mess with the code.

I've got a tumblr site up with my progress on the project at http://sfe-mp3.tumblr.com/, caveats are that I just started messing with it and the blog is subject to a lack of updates at any time :D.
