Here's my biggest CKT file... if you expected me to tell you how it works in this little page, you MUST have a mental disease, Please download the Zip File that includes a Word Document that explains the circuit and theory, sample aplications for it, instruction set for Ktulu Assembler, a kewl application that creates a ckt file with your program already loaded, hardware description, and much more. The documentation is in spanish, so you can start learning.
