Do you want gigabytes of storage for your microcontroller? Would you like a simple way to tranfer files from your PC to your picaxe or arduino or other micro project?
This little projects demonstrates the uDrive that can be set up as an extra drive on a PC. Copy files to and from the SD card, then put it in the uDrive and talk to it with 5 simple commands:
Read - Read a file off the drive
Write - Write a file to the drive
Dir - get the directory listing of files on the drive
Erase - erase a file
Initialise - send 1 byte at your preferred baud rate
Step 1: Connecting to your microcontroller
Connection uses 5 wires: Gnd, Power, Tx, Rx and an optional reset line. The reset line can be left unconnected if no reset is needed.
The uDrive works from 3 to 5V so can interface to a wide range of controllers.
