Reading Xilinx Serial EEPROM with Arduino

2) Send it to the PC

3) Goto #1 as many times as needed -1
By including the serial communications and SPI libraries, it’s extremely easy to do this with Arduino and the code looks almost like the silly pseudocode above.   There is a little setup, of course, but it’s straightforward enough that even a novice could take our code and start stealing bitstreams.   But that would be in very poor taste so please refrain.Here is the source code for the project.   SerialEE.zip

To use it, simply upload it to Arduino.   Then close the Arduino IDE and open hyperterminal or some other terminal program to receive the data.   Configure to 115.2k.   Reset the Arduino and off it will go.
