Description: This is the Olimex prototyping board for the LPC2148 processor pre-loaded with the powerful ALFATxp firmware from GHI electronics. The ALFATxp firmware is basically a FAT16 IC that is controlled with a serial based command set. But there are many more perks lurking beneath the surface! The ALFATxp firmware runs fast, clean, and supports many interfaces (SPI, I2C, and UART) and many formats (FAT12, FAT16, FAT32). On top of all of that, the LPC2148 enumerates as a USB mass storage device and can even run Java code internally!

Here is how one might setup a system : Your micro talks to the LPC2148 (loaded with ALFATxp firmware) telling it to log certain temperature information to an SD card. The ALFAT firmware takes care of all the directory structure and FAT updating. When the LPC2148 is attached to a computer, the USB kicks in and you see a new drive on your computer (Windows, Linux, and Mac supported!). On this new drive you will be able to access the files that your micro created - downloading the data to your computer by dragging and dropping!

The ALFATxp firmware also incorporates Java Virtual Machine (JVM). This means that you can load java code directly onto the mass storage device through your computer, and that java code will run on the LPC2148. There is no need for an external microcontroller!
